How much copper is in an old-style refrigerator: accurate calculation + methods of extraction without risks

Old Soviet refrigerators are a real treasure trove for those who sell non-ferrous scrap metal. Unlike modern models, where copper is almost completely replaced by aluminum and plastic, devices ZIL-63, Minsk-16 or Biryusa-3 contain kilograms of this valuable metal. But exactly how much copper can be extracted from a 30-50 year old refrigerator? And how to do this without breaking the law and without putting yourself in danger?

In this article we will examine exact composition of copper components old-style refrigerators, We will provide weight data for popular models, and also tell you which parts contain the maximum amount of copper. You will learn how to properly dismantle the compressor and pipes so as not to lose precious grams, and where to sell scrap at a good price. And also why some “craftsmen” lose up to 30% of copper during disassembly and how to avoid this.

Which refrigerator parts contain copper: complete list

In Soviet refrigerators, copper is concentrated in three key components: compressor, capillary tubes (rear lattice) and capillary tubes. However, not all parts are equally valuable - for example, the winding of a compressor electric motor can contain up to 1.2-1.5 kg of pure copper, while thin tubes will give only 200-300 grams.

Here is a complete list of copper components:

  • 🔧 Compressor winding —the “heaviest” part (0.8-1.5 kg of copper). It is located inside a sealed housing and requires careful opening.
  • 🌀 Condenser (rear grille) —aluminum plates + copper tubes (150-400 g of copper). Often confused with purely aluminum radiators.
  • 🧵 Capillary tube —a thin copper tube (50-150 g) running from the condenser to the evaporator.
  • Start relay —contains copper contacts (20-50 g), but disassembling it is unprofitable.
  • 🔌 Power cable - stranded copper wire (30-100 g), but usually it is cut off during disposal.

Important: in refrigerators late Soviet period (1980s), copper was already partially replaced by aluminum. For example, in Biryusa-18 the capacitor could be completely aluminum, and in ZIL-63 (1970s) - with copper tubes. To avoid mistakes, check with a magnet: copper does not magnet, aluminum too, but it is given out by its silvery color and lightness.

In order not to guess from the coffee grounds, we collected data on the real weight of copper components in the most common models. The numbers are approximate, since the weight depends on the year of manufacture and modification. For example, Minsk-16 1975 contained 200-300 grams of copper more than the 1985 version.

Refrigerator model Years of manufacture Copper in the compressor (kg) Copper in the condenser (g) Copper in tubes (g) Total (kg)
ZIL-63 (Moscow) 1965–1980 1.2–1.4 300–400 100–150 1.6–1.9
Minsk-16 1970–1985 0.9–1.1 250–350 80–120 1.2–1.5
Biryusa-3 1973–1990 1.0–1.2 200–300 70–100 1.3–1.6
Oka-6 1980–1995 0.7–0.9 150–250 50–80 0.9–1.2
Saratov-2 1968–1982 1.3–1.5 350–450 120–180 1.8–2.1

Please note: the table indicates net weight of copper, excluding insulation, solder and other impurities. At scrap metal collection points you will only be paid for cleaned copper, so plastic, rubber and oxides must be removed before delivery. More details about this in the section on dismantling.

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

Disassembling a refrigerator for copper is a labor-intensive and potentially dangerous process. The main risks: cut on sharp metal edges, freon leakage (older models used harmful R-12) and electric shock (capacitors can store charge for years). Below is a safe algorithm of actions.

Disconnect the refrigerator from the network for at least 24 hours

Put on rubber gloves and safety glasses

Prepare tools: grinder, wire cutters, screwdrivers

Take the refrigerator outside or into a well-ventilated area

Put a film under it (oil leaks are possible)-->

Step 1. Removing the compressor

The compressor is located at the bottom of the refrigerator, usually covered with a casing. Your task is to carefully cut off the tubes connecting it to the condenser and evaporator. Use grinder with a thin disk or pipe cutter. Do not try to bite off the tubes with wire cutters - this way you will deform the copper and lose some of the metal.

  • ⚠️ Attention: Do not turn on the compressor after cutting the tubes! Freon may remain under pressure in the system.
  • 🔧 After disconnecting the tubes, unscrew the compressor mounting bolts (usually 3-4 pieces).
  • 🔨 Open the compressor housing by cutting off the top cover with a grinder. Inside you you will find a copper winding.

Step 2. Removing copper from the condenser

The rear grille of the refrigerator (condenser) consists of aluminum plates and copper tubes. To separate the copper:

  1. Cut the tubes at the base (where they enter the compressor and evaporator).
  2. Carefully straighten the aluminum plates with pliers.
  3. Pull the copper tubes out of the plates. If they are soldered, heat them with a soldering iron.

Step 3. Cleaning copper from impurities

Reception points accept only pure copper without insulation, solder or paint. For cleaning:

  • 🔥 Burn the wires over an open fire (for example, with a gas torch) to remove the insulation.
  • 🧴 Soak the parts in vinegar or citric acid for 1-2 hours to remove oxides.
  • 🧼 Wipe the copper with a metal brush or sandpaper.

How much can you earn on copper from the refrigerator?

The price of copper at collection points varies depending on the region and the purity of the metal. As of 2026, the average prices are as follows:

  • 💰 Pure copper (wires, tubes) — 600–800 rub/kg
  • 💰 Copper with impurities (compressor winding) — 400–600 rub/kg
  • 💰 Brass (an alloy of copper with zinc) — 300–450 rub/kg

Let's calculate income using an example ZIL-63:

  • Compressor: 1.3 kg × 600 rubles = 780 rubles
  • Condenser: 0.35 kg × 700 rubles = 245 rubles
  • Tubes: 0.12 kg × 700 rub = 84 rubles
  • Total: ~1100 rubles for one refrigerator.

It would seem that the amount is small. But if you consider that:

  • 📦 One refrigerator weighs 50-80 kg, and copper - only 1.5-2 kg. The rest of the scrap metal (aluminium, steel) can also be handed over.
  • 🚛 For a truckload of Soviet refrigerators (10-15 pieces) you can get 15-20 thousand rubles.
  • 🔄 Copper prices are rising every year (in 2020 a kg cost 300-400 rubles).
Where to sell copper is more expensive?

In small towns, collection points often lower prices. It is better to transport copper to regional centers or look for private buyers through Avito/Yula. For example, in Moscow and St. Petersburg the difference in price can reach 100-150 rubles/kg. It is also more profitable to rent in large quantities (from 10 kg) - many points give a bonus of 5-10%.

From a legal point of view, disassembling own a refrigerator for spare parts is not prohibited. However, there are several pitfalls:

  1. Freon disposal. Old refrigerators use freon-12, which destroys the ozone layer. Its leak is punishable by a fine under Art. 8.2 Code of Administrative Offenses (up to 2 thousand rubles for individuals). To avoid problems, before disassembling, call a recycling specialist (costs ~500-1000 rubles). R-12 (Freon-12), which destroys the ozone layer. Its leak is punishable by a fine under Art. 8.2 Code of Administrative Offenses (up to 2 thousand rubles for individuals). To avoid problems, call a disposal specialist before disassembling (costs ~500-1000 rubles).
  2. Transportation of scrap metal. If you are bringing a large quantity of copper for delivery (from 50 kg), the police may have questions. It is better to have a receipt or a contract for the purchase and sale of a refrigerator with you.
  3. Taxes. If you sell copper regularly (for example, dismantle 10+ refrigerators per month), this may be considered a business activity. In this case, you need to register an individual entrepreneur.

If the refrigerator was picked up from a landfill or purchased from unknown persons, it is better to have documents confirming its origin. Otherwise, the collection point may refuse to accept copper, suspecting it to be stolen.

Top 5 mistakes when removing copper from the refrigerator

Many beginners lose up to 30% of copper due to improper disassembly. Here are the most common mistakes and how to avoid them:

  • Use wire cutters instead of a grinder. When biting off the tubes with wire cutters, the copper is flattened, and some of the metal remains in the “bitten” edges. That's right - cut with a grinder at an angle of 45°.
  • Incomplete removal of the winding from the compressor. Copper wires remain inside, which are difficult to get out without special tools. Solution: cut the compressor housing into two halves.
  • Ignoring small details. Many people forget about the copper contacts in the relay, the terminals on the compressor and the power wires. Their total weight can reach 200-300 g.
  • Crude copper. Reception points reduce the price for dirty metal. For example, a winding with varnish insulation can be rated as “copper with impurities” (400 rubles/kg instead of 700 rubles/kg).
  • Working without protection. Sharp metal edges, freon and dust from insulation can cause serious harm to health. Minimum set: gloves, goggles, respirator.

Another typical mistake is disassembling the refrigerator in a residential area. Freon and compressor oils have a strong odor and are toxic. It is better to do this outside or in a garage with good ventilation.

Alternative ways to make money on an old refrigerator

If disassembling for copper seems too labor-intensive, there are other ways to monetize an old refrigerator:

  • 🔄 Entire sale. On Avito or in the “Used Equipment” groups, Soviet refrigerators are bought for 1-3 thousand rubles. Buyers: summer residents, collectors of retro equipment, repairmen.
  • ♻️ Release for recycling. Some companies remove old equipment for free, and sometimes even pay a symbolic amount (200-500 rubles). For example, the “Ecotechnics” or “Clean City” programs.
  • 🛠️ Repair and resale. If the refrigerator is generally working, but requires minor repairs (replacing the seal, refilling freon), it can be restored and sold for 3-5 thousand rubles.
  • 🎨 Handmade and art objects. Original things are made from old refrigerators: bar counters, tool cabinets, even mini-saunas. On Etsy or the Crafts Fair, such products are sold for 5-15 thousand rubles.

If the refrigerator is in poor condition, but the compressor works, it can be sold separately. Craftsmen use old compressors for:

  • 🔧 Homemade spray guns.
  • 💨 Air compressors for the garage.
  • 🚜 Pumps for watering the garden.

Price for used compressor from a Soviet refrigerator - 500-1500 rubles, depending on the model and condition.

FAQ: Frequently asked questions about copper in refrigerators

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

Yes, but it will take longer. Instead of a grinder, you can use:

  • 🔨 A hacksaw for metal (for tubes and the compressor housing).
  • 🗡️ Wire cutters with long handles (for thin tubes).
  • 🔥 A blowtorch (for melting solder on capacitor).

However, without a grinder, you risk losing some of the copper due to sloppy cuts.

How to distinguish copper from brass in the refrigerator?

Brass (an alloy of copper and zinc) is similar in appearance to copper, but has a lighter, yellowish tint. It's easy to check:

  1. 🔍 Color: copper is red-brown, brass is yellow.
  2. 🧲 Magnet: neither copper nor brass are magnetic, but brass is often coated with nickel, which is weakly attracted.
  3. 🔨 Sound: if you knock with a metal object, copper makes a duller sound.
  4. 💧 Vinegar: drop a drop of vinegar - copper will turn green in 5-10 minutes, brass will not.

Brass is rarely found in refrigerators - usually in faucet valves or decorative elements.

Is it worth disassembling the refrigerator for copper if it is still working?

No, if the refrigerator is working. Even taking into account the rise in copper prices, you will receive 1-1.5 thousand rubles for metal, while a working Soviet refrigerator can be sold for 2-5 thousand rubles. An exception is if repairs will cost more (for example, a compressor has failed, and a new one costs 4-6 thousand rubles).

Also consider ecological aspect: a working refrigerator, even if old, less harmful to nature than disassembled for spare parts.

Which refrigerators contain the maximum amount of copper?

The leaders in copper content are:

  1. ZIL-63 (1965–1980) - up to 2.1 kg.
  2. Saratov-2 (1968–1982) - up to 2 kg.
  3. Minsk-12 (1960s) - up to 1.8 kg.
  4. Biryusa-2 (1970s) - up to 1.6 kg.

The older the model, the more copper it contains. Refrigerators of the 1990s (for example Atlant or Orsk) already contain 0.5-0.8 kg, while modern ones contain less than 0.1 kg.

What to do if there is freon left in the refrigerator?

Freon R-12 (used until the 2000s) is dangerous for the ozone layer, but is not toxic to humans in small doses. To release it safely:

  1. Take the refrigerator outside.
  2. Wear a respirator and gloves.
  3. Puncture the tube with a thin nail or awl in a place where it does not come into contact with other parts.
  4. Move away 2-3 meters and wait 10-15 minutes.

⚠️ Attention: Do not do this indoors! Freon is heavier than air and can accumulate near the floor.
