The question of how many kilograms of copper is in the refrigerator often arises those who plan to recycle household appliances or are engaged in professional dismantling. It’s worth noting right away that pure precious metal cannot be found here, but non-ferrous metals make up a significant part of the cost of scrap. The weight of copper depends on the dimensions of the unit, year of manufacture and type of compressor.
The average household refrigerator contains from 0.5 to 1.5 kg of copper components. However, this figure may vary. In old Soviet models, the content of non-ferrous metals was higher due to massive heat exchangers. Modern “no-frost” systems use thinner tubes, but have complex electronic filling.
To accurately understand the value of the device, you need to understand its internal structure. Simply weighing the entire refrigerator is not enough, since the bulk of the weight is made up of steel and plastic. To get the maximum profit upon delivery, dismantling and sorting of materials is often required.
Where exactly is copper located in the refrigerator
The main accumulation of valuable metal is concentrated in the cooling system. It is here that the circuits through which the refrigerant circulates pass. Condenser tubes and the evaporator is most often made of copper or aluminum, but in expensive and older models it is Cuprum that predominates. You can find them on the back wall or inside the freezer.
The second important unit is the compressor. Inside this sealed unit is the motor winding. It is used for winding coils copper varnished wire. Depending on the power of the motor, the weight of this winding can be a significant part of the total amount of non-ferrous metal in the product. However, it is almost impossible to remove it without damaging the housing.
⚠️ Attention: The internal unit of the compressor is under pressure and contains oil. Opening it using makeshift methods (sawing, punching) is dangerous and prohibited by disposal rules.
The third source is electrical wiring and control boards. The cables running from the outlet to the compressor, thermostat and lamps have copper conductors. Modern models with electronic control also contain precious and non-ferrous metals on the circuit boards, but their extraction requires chemical processing.
Why is there less copper in new refrigerators?
Manufacturers are trying to reduce the cost and weight of the product. Aluminum is cheaper and lighter, so the tubes become thinner, and composite materials or coated aluminum are sometimes used in motor windings.
Table: Approximate copper yield by model
The weight of the extracted metal directly depends on the type of refrigerator. Single-chamber models are inferior to two-chamber giants. Below are averaged data that will help you navigate the volume of potential scrap.
| Refrigerator type | Years of manufacture | Total weight (kg) | Copper (approximately, kg) |
|---|---|---|---|
| Small (single-chamber) | 1990-2010 | 35-45 | 0.4 - 0.6 |
| Standard (two compartments) | 2000-2015 | 55-70 | 0.7 - 1.1 |
| Side-by-Side (American) | 2010-2026 | 90-120 | 1.2 - 1.8 |
| Soviet (ZIL, Biryusa) | 1970-1990 | 60-80 | 1.0 - 1.5 |
As can be seen from the table, old Soviet units often turn out to be richer in non-ferrous metals than some modern Chinese analogues. This is due to the use of thicker tube walls and a lack of material savings in the past. However, they also weigh significantly more, which affects logistics during delivery.
It is worth considering that the data in the table is given for a completely disassembled device. If you hand over the entire refrigerator, the receiver will evaluate it as “refrigerator scrap” or “black scrap,” which costs several times less. The difference in price can reach 300-400%.
Factors influencing the amount of metal
You should not expect that each device will contain exactly one kilogram of copper. There are many variables that change the final figure. Manufacturers are constantly optimizing designs, replacing expensive materials with more affordable analogues.
The first factor is the design of the heat exchanger. Systems using freon R600a (isobutane) use thinner tubes because this gas is more efficient. Therefore, they contain less copper. Old freon systems (R12, R134a) required more powerful equipment and thick pipes. refrigerant type and heat exchanger design. Systems using freon R600a (isobutane) use thinner tubes because this gas is more efficient. Therefore, they contain less copper. Older freon systems (R12, R134a) required more powerful equipment and thicker tubes.
- 🔹 Energy efficiency class: models of class A++ and higher often have more complex cooling systems with additional circuits, which can increase metal consumption.
- 🔹 The presence of a No Frost system: such refrigerators are equipped with additional fans and heating elements, which also contain copper, but the main evaporator circuit is often made of aluminum for better heat transfer.
- 🔹 Manufacturer brand: European brands (Liebherr, Bosch) traditionally use higher quality materials compared to budget segments of the market.
The age of the equipment is also important. If the refrigerator is more than 15 years old, there is a 90% chance that its radiator is made of pure copper. In equipment younger than 5-7 years old, manufacturers are massively switching to aluminum or steel with copper coating, which significantly reduces the value of scrap.
The process of dismantling and extraction
In order to get clean scrap, the refrigerator will have to be disassembled. This is a labor-intensive process that requires tools and safety precautions. Simply unplugging the power cord is not enough.
You should start by dismantling the plastic elements and internal filling. Shelves, drawers and compactors are of no value to metallurgy. Then the back panel where the capacitor is located is removed. This is where the bulk of the tubular metal is located.
Sequence of actions:1. Disconnect from the network (pull out the plug).
2. Remove the plastic cover from the compressor.
3. Cut through the compressor tubes (be careful, gas may escape).
4. Disconnect the capacitor grid from the housing.
5. Remove the compressor (fastening bolts).
Separating the tubes from the steel body is the most difficult stage. They are often glued or welded. The use of open fire for annealing paint is prohibited, since the combustion of insulation and plastic releases toxic substances, and copper can oxidize, losing its value.
⚠️ Attention: When the cooling system is depressurized, gas enters the atmosphere. Although modern freons are not toxic in small doses, they destroy the ozone layer. On an industrial scale, gas utilization is mandatory.
☑️ Tools for disassembly
The difference between copper and brass
When sorting scrap, it is important not to confuse copper with brass or bronze. These alloys are cheaper, and you won’t be able to sell them at the price of pure copper. Receivers can easily determine the substitution by spectral analysis or even visually.
Pure copper has a characteristic reddish-pink tint. If the metal is yellow, golden or has a greenish coating (patina), it is most likely brass. In refrigerators, brass inserts can be found in connecting fittings, shut-off valves or compressor bushings.
It is also worth paying attention to the wires. The veins in them should be bright orange. If the conductor is silver, it is aluminum. Aluminum wiring is valued much lower. In some older models, the motor winding could be made of aluminum, which immediately makes the compressor less valuable for non-ferrous metal mining.
Oxidation is a natural process. The surface of copper darkens over time, becoming covered with a patina. This does not reduce the value of the metal when melted down, but may make visual identification difficult. To check the material, you can make a small cut: the inside color should be fresh and red.
Economic feasibility and prices
Is the game worth the candle? To answer this question, you need to compare the time and effort required with the market value of the scrap. The price of copper (Mix) fluctuates, but is usually a significant amount per kilogram. However, one refrigerator is not a fortune.
If you hand over the entire refrigerator, you will receive approximately 500-1000 rubles (depending on the region and collection point). If you disassemble it yourself, sort copper, aluminum and steel, revenue can grow to 2000-3000 rubles or more per unit of equipment.
However, you must take into account:
- 📉 Time: It takes from 40 minutes to 1.5 hours to qualitatively cut one unit.
- 🚚 Logistics: Transportation of a heavy case and waste removal (plastic, glass) can cost money.
- ⚖️ Reception: Not all points accept scrap from individuals in small volumes or require passport data.
For the business of recycling equipment, disassembly makes sense only on an industrial scale (hundreds of units per month). For a private individual, it is most profitable to find a refrigerator that has already been disassembled, or to have access to free equipment in large quantities.
Is it possible to hand over a refrigerator with freon?
Officially, collection points are required to have a license to work with ozone-depleting substances. Many “gray” receivers accept equipment with gas, but make a discount for the risk. Large plants require preliminary removal of freon.
Where is copper located in the compressor?
Copper is located in the form of the stator winding of an electric motor. It is wound on a metal core. To get to it, you need to cut the compressor housing, which is difficult to do without special equipment.
Does the brand of the refrigerator affect the amount of copper?
Yes, it does. European brands (Liebherr, Siemens) and old Soviet models (ZIL, Saratov) traditionally contain more non-ferrous metals in radiators and wiring than budget Chinese or Turkish assemblies.
Which is more expensive: copper tubes or windings?
Their price per kilogram is the same (if it is pure copper M1/M2). However, the tubes are easier to clean and hand over, since they already have the appearance of salable scrap, while the winding is often accepted with a coefficient of blockage (varnish, iron).
