How much copper is contained in a Soviet refrigerator: analysis by model and scrap price in 2026 year

Soviet refrigerators are real “copper treasures” for those who collect and sell non-ferrous scrap metal. Unlike modern models, where manufacturers save on materials, in devices from the times of the USSR, copper was used everywhere: in compressor windings, capillary tubes, heat exchangers and even in some parts of the thermostat. But how much of this valuable metal can be extracted from the old ZIL-63, Biryusy-3 or Minsk-16? And is it even worth spending time on disassembling?

Many people mistakenly think that the main source of copper is compressor, but in fact the lion's share falls on thin tubes of the cooling system, which braid the back wall of the refrigerator. Moreover, the weight of copper varies not only from the model, but also from the year of manufacture: for example, in the early Saratov-2 (1960s) copper could be up to 1.8–2 kg, while in the later Oke-6 (1980s) this figure dropped to 1–1.2 kg. The difference is significant, especially if you sell scrap wholesale.

In this article we will figure out exactly where copper is hidden in Soviet refrigerators, we will provide accurate data on popular models (including rare specimens like Donbass-7), we will tell you how to properly extract the metal without risk to health, and we will calculate how much you can earn by selling scrap to 2026. We’ll also warn you about the pitfalls that metal collection points are silent about.

Where copper is hidden in a Soviet refrigerator: key components

If you decide to disassemble old refrigerator for spare parts, the first thing you need to understand is which parts contain copper. The main “locations” of this metal:

• 🔧 Compressor windings — here copper is used in its pure form (wire with a diameter of 0.5–1 mm). The weight of the windings depends on the power of the motor: in low-power ZIL-62 - up to 300–400 g, in large Minsk-126 - up to 600–800 g.
• 🌀 Capillary tubes and heat exchanger —thin copper tubes (diameter 2–6 mm) braiding the back wall. Their total weight can reach 1–1.5 kg depending on the model.
• ⚙️ Start relay and thermostat — here copper is present in contacts and coils, but its amount is minimal (up to 50–100 g).
• 🔌 Connecting wires —in Soviet refrigerators, stranded copper wires (cross-section 0.75–1.5 mm²) were often used. Their total weight rarely exceeds 200 g.

It is important to understand that not all copper is equally valuable for the receiving point. For example, compressor windings usually accepted at a higher price than pipes with residual freon or oil - they will have to be cleaned, but thin capillary tubes often go into the “copper in varnish” category (due to the varnish). coating), which reduces their cost by 10–15%.

Another nuance: in some models (for example, Oka-6 or Polyus-10), some of the tubes could be replaced with aluminum or steel - this can be seen by the color (aluminum is silver, copper is reddish-brown). Before disassembling, be sure to check the metal with a magnet: copper does not magnetize, unlike steel.

Table. copper content in popular models of Soviet refrigerators

In order not to guess from the tea leaves, we collected data for the most common models. The figures are indicated for refrigerators in initial state (without preliminary disassembly or loss of parts) The weight of copper is given taking into account all components, including the compressor, pipes and wires.

An important point: the table shows the weight pure copper, but in practice you will get 10–20% less due to losses during disassembly, cutting tubes and cleaning windings. For example, if Biryusa-3 according to your passport there is 1.3 kg of copper, in reality you will hand over about 1–1.1 kg after separating plastic, rubber and other impurities.

It is also worth considering that in some refrigerators (especially those produced after 1980), some of the copper parts could have been replaced with cheaper analogues. For example, in Oke-6 sometimes there are aluminum heat exchangers - their weight is 3 times less than that of copper ones.

How to remove copper from the refrigerator: step-by-step instructions

Disassembly Soviet refrigerator on copper is not an easy task. There are three key points:

1. Safety - freon may remain in the system (even after 30–40 years!), and the compressor is under pressure.
2. Tools - you will need a grinder, wire cutters, screwdrivers and protective equipment (respirator, gloves).
3. Economic feasibility - if copper weighs less than 1 kg, perhaps the game is not worth the candle.

Algorithm of actions:

Unplug the refrigerator (even if it is not working)|

Take it outside or into a well-ventilated area|

Wear a respirator and gloves (dust and oil are toxic)|

Prepare containers for sorting metals (copper, aluminum, steel)-->

Step 1. Dismantling the compressor

The compressor is located at the bottom of the refrigerator (usually hidden under the casing). It must be carefully disconnected by cutting the tubes with wire cutters. Do not try to cut the compressor with a grinder —there may be oil or freon inside, which can ignite! manually:

1. Remove the start relay (3 screws).
2. Unscrew the compressor cover (a hexagon may be required).
3. Remove the windings (copper wire on coils).

Step 2. Removing the heat exchanger

The back wall of the refrigerator is usually covered with a metal sheet. Underneath it you will find a labyrinth of tubes - this is the heat exchanger. To remove it:

• Unscrew the fastening bolts (WD-40 may be needed - rust often “sticks”).
• Carefully bend the tubes away from the grille (they are fragile!).
• Cut the tubes with wire cutters, leaving the maximum length.

Step 3. Cleaning and sorting

Before delivery, copper must be cleared of:

• The varnish coating (on the windings) - can be burned or mechanically cleaned.
• Freon/oil residues - rinse with gasoline or acetone.
• Solder (at the joints of the tubes) - it contains tin and lead, which reduce the price of copper.

What to do if the tubes are clogged with dirt?

If dirt or oxides have accumulated inside the tubes, they can be cleaned with a steel cable (as for sewerage) or Rinse under pressure with water and citric acid. This will increase the weight of “pure” copper by 5–10%.

How much can you earn on copper from a Soviet refrigerator in 2026

The price of scrap copper fluctuates depending on the region, the purity of the metal and the dollar exchange rate. At the time of writing (2026), the current prices in Russia are as follows:

• 🟤 Pure copper (wire, uncoated tubes) — 700–900 rub/kg.
• 🟡 Copper in varnish (compressor windings) — 500–700 rub/kg.
• 🔴 Copper scrap with impurities (tubes with solder, oxides) — 300–500 rub/kg.

Let's calculate using an example Biryusy-3 with 1.3 kg of copper:

• Suppose you extracted 1 kg of clean tubes and 300 g of windings in varnish.
• Clean tubes: 1 kg × 800 rubles = 800 rubles.
• Windings: 0.3 kg × 600 rubles = 180 rubles.
• Total: 980 rub for one refrigerator.

Is it worth it? If the refrigerator is lying around idle, then yes. But if you have to take it to the reception point (and it weighs 50–80 kg), consider the cost of transport. In addition, many points only accept copper in bulk (from 5–10 kg), so you can’t get away with just one refrigerator.

Another nuance: they are valid in some regions seasonal coefficients. For example, in winter the price of copper can fall by 10-15% due to low demand, and in summer it can rise. Before going to the collection point, check the current prices by phone.

⚠️ Attention! Some scrap metal collection points refuse to accept copper from refrigerators if it is not cleared of freon or oil. This is due to environmental regulations. Check the requirements in advance so as not to carry scrap in vain.

Pitfalls: what 90% of copper sellers do not know

At first glance, disassembling a refrigerator for copper seems like a simple task: take an angle grinder, cut it, hand it over - you get the money. But in practice, there are a lot of nuances that even experienced scrap collectors are silent about.

Problem No. 1: Freon in the system

Even if the refrigerator has not worked for 20 years, freon may remain in the pipes and compressor (especially in models before the 1980s, where it was used R-12). When heated (for example, when cutting with a grinder), it releases phosgene poisonous gas, which was used in the First World War as a chemical weapon. Symptoms of poisoning: cough, dizziness, vomiting.

How to avoid: disassemble the refrigerator outside, wearing a respirator, and do not cut pipes under pressure.

Problem No. 2: "Dirty" copper

Reception points often lower the price, citing the "contamination" of copper. For example:

• Tubes with solder residues (tin + lead) can be equated to "brass" - the price is 30% lower.
• Windings with varnish weigh more due to the varnish, but are paid as "copper insulation."
• If copper is mixed with aluminum (for example, in a heat exchanger), it can be accepted at the price of “mixed scrap.”

Problem No. 3: Legal risks

Since 2021, the rules for the delivery of scrap metal have become more stringent in Russia. Now collection points are required to:

• Fix the passport details of the deliverer (if the transaction amount exceeds 15,000 rubles).
• Check the origin of scrap (if you are carrying 5 refrigerators, they may ask for documents for them).
• Refuse acceptance if the copper is “suspiciously pure” (they may suspect theft from enterprises).

⚠️ Attention! If you are selling copper from several refrigerators, keep receipts or sales contracts (if you bought used equipment). Otherwise, questions may arise from law enforcement agencies.

Alternative ways to use copper from the refrigerator

It is not necessary to scrap copper. If its quantity is small (up to 1 kg), you can find a more profitable use:

• 🔌 Homemade electrical appliances - thick copper tubes make excellent heatsinks for soldering irons or housings for homemade induction furnaces.
• 🌿 Decorative items - copper tubes are used to create LED chandeliers, hot stands or even steampunk style furniture.
• 🔋 Batteries and batteries —pure copper can be melted into anodes for galvanic baths (for example, for copper plating of parts).
• 💰 Sale on Avito/Yula - some handicraft craftsmen buy copper tubes from refrigerators for their projects (the price may be higher than at the collection point).

If you have soldering skills, from compressor windings can be made:

• Powerful electromagnets (for lifting metal objects).
• Tesla coils (for experiments with high voltage).
• Homemade transformers (for example, for welding machine).

Calculation example: if you sell 1 kg of copper tubes from ZIL-63 not for scrap, but to a handmade craftsman, you can help out 1,200–1,500 rubles (30–50% more than at the reception point). The main thing is to present the product correctly: clean the copper, take a photograph and indicate in the ad that it is "pure copper without impurities, ideal for creative projects".

Models Soviet refrigerators, which contain the most copper

If your goal is maximum profit from selling copper, pay attention to these models. They either had powerful compressors or a complex cooling system with a large number of tubes:

• 🥇 Saratov-2/Saratov-3 (1960–1972) - up to 2 kg of copper. One of the most "copper" refrigerators in the USSR. The compressor weighs about 20 kg, and the windings in it contain up to 700 g of pure copper.
• 🥈 ZIL-62 / ZIL-63 (1950–1965) — 1.5–1.8 kg. heat exchanger and heavy compressor.
• 🥉 Donbass-7 (1970–1980) — 1.3–1.6 kg. A rare model, but very rich in copper.
• 4️⃣ Biryusa-3 (1963–1975) — 1.2–1.4 kg. A classic that is easy to find on the secondary market.
• 5️⃣ Minsk-126 (1980–1985) — 1.0–1.3 kgLess copper than in older models, but easier to use. disassembly.

If you come across a refrigerator Oka-6 or Polyus-10 (1980–1990s), do not expect a large amount of copper - there is no more here 0.8–1 kg. In these models, the USSR has already begun to save on materials, replacing copper with aluminum.

Interesting fact: in industrial refrigerators (for example Kharkov-240 or Leningrad-280) copper could be up to 3–4 kgBut such specimens are extremely rare and are usually expensive as a rarity.

⚠️ Attention! In refrigerators produced after 1985, copper was often combined with aluminum. For example, the heat exchanger could be half aluminum. Check the metal with a magnet or by using a magnet. blossom! Oke-7 the heat exchanger could be half aluminum. Check the metal with a magnet or by color!

FAQ: Frequently asked questions about copper in Soviet refrigerators

Is it possible to remove copper from the refrigerator without a grinder?

Yes, but this will take more time. Instead of a grinder, use:

• A hacksaw (for tubes).
• Pliers or side cutters (for compressor windings).
• A blowtorch (for melting solder at the joints).

The main thing is to take your time so as not to hurt your hands on the sharp edges of the tubes.

How to distinguish copper from brass in refrigerator tubes?

Copper and brass are similar in appearance, but there are key differences:

• Color: copper is reddish-brown, brass is yellowish.
• Weight: brass is heavier (density 8.4–8.7 g/cm³ versus 8.9 g/cm³ for copper).
• Sound: if you hit a copper tube with a hammer, the sound will be louder.
• Magnet: neither copper nor brass are magnetic, but brass may be slightly attracted due to iron impurities.

If in doubt, take the sample to the receiving point - they will determine the composition using acid or a spectrometer.

How much does it cost to disassemble a refrigerator for copper in a workshop?

If you do not want to disassemble the refrigerator yourself, you can contact the receiving workshop scrap metal Cost of the service:

• Independent delivery of the refrigerator: 500–1,000 rubles (depending on the model).
• Departure of the technician to your home: 1,500–3,000 rubles (plus the cost of garbage removal).

Usually workshops take 30–50% of the cost of the extracted copper. For example, if there is 1.5 kg of copper in the refrigerator, you will be paid 700–900 rubles for it, and 300–500 rubles will be charged for disassembly. As a result, the net profit will be 200–600 rubles.

Is it possible to sell the entire refrigerator as scrap?

Yes, but it is less profitable. Reception points evaluate the refrigerator as “mixed scrap” by weight:

• Steel case: 10–15 rubles/kg.
• Aluminum (if yes): 80–120 rubles/kg.
• Copper: 500–700 rub/kg (but its weight is taken into account at minimum prices).

Example: refrigerator Biryusa-3 weighs 60 kg, of which:

• Steel - 40 kg × 12 rubles = 480 rubles.
• Aluminum - 5 kg × 100 rubles = 500 rubles.
• Copper - 1.2 kg × 600 rubles = 720 rubles.
• Total: 1,700 rubles (versus 900–1,200 rubles for self-disassembly).

Conclusion: it is more profitable to hand over the whole thing, but only if you do not have time for disassembly.

What documents are needed to hand over copper from the refrigerator?

Since 2021, the rules have become stricter. To hand over copper you will need:

• Passport (if the transaction amount exceeds 15,000 rubles).
• A purchase and sale agreement for a refrigerator (if it is not yours).
• A check or invoice (if you are handing over as a legal entity).

Some reception points ask you to show a certificate from the Housing Office that the refrigerator was your property. Check the requirements in advance by phone.
