The question of how much ferrous metal is contained in the refrigerator often arises among those who plan to get rid of old household appliances or want to assess the potential profit from delivering the equipment to scrap metal collection points. At first glance, the bulky body of the refrigerator seems entirely made of steel, but the real picture is much more complex and interesting from the point of view of materials science and the economics of recyclable materials. The weight of ferrous metal makes up the bulk of the unit, but is far from 100%.
The average two-chamber refrigerator weighs from 50 to 80 kilograms, but it contains approximately 60-70% pure iron (steel). The rest of the weight is distributed between copper, aluminum, plastic, insulating materials and refrigerants. Understanding the exact composition necessary not only for the correct assessment of the value of scrap, but also for safe disposal, since some components require a special approach.
In this article we will analyze in detail what they are made of consists of the “hardware” of your refrigerator, how the dimensions and year of manufacture affect the weight of the metal, and we will also consider the economic feasibility of dismantling it yourself before delivery. You will learn why an empty case costs less than a properly disassembled unit, and what hidden resources can be extracted from old equipment.
⚠️ Attention: Before starting any disassembly work, make sure that the refrigerator is completely unplugged for at least 24 hours. There may be residual pressure in the circulation system, and in older models there may be potentially dangerous refrigerants.
Total weight and composition of metal scrap
To answer the question, how many kg of ferrous metal is in the refrigerator, it is necessary to consider the average indicators for various types of equipment. Weight directly depends on the volume of the chambers, the number of compressors and the year of production. Old Soviet models, such as ZIL or Saratov, were distinguished by thicker case walls and heavier compressors, which increased the share of metal in the total mass of the product.
Modern refrigerators are striving for lightweight construction, using thinner steel and composite materials, but the basic principle remains the same: the body, doors and rear grille are predominantly ferrous metal. Ferromagnetic properties allow steel to be easily separated from plastic and insulation using a conventional magnet, which simplifies primary sorting.
It is important to note that the weight of “dirty” scrap (a whole refrigerator) and “clean” (disassembled case) at collection points is estimated differently. Purchasing points often apply a reduction factor for the presence of non-metallic inclusions, plastic and insulation. Therefore, knowing the exact weight of the useful metal yield is critical for calculating profitability.
What the body is made of: ferrous versus non-ferrous metal
The main mass of the refrigerator, about 40-50 kg in a standard two-chamber model, is cold-rolled steel. The outer casing, internal walls (in some models), doors and shelves are made of it. It is this material that is classified as black scrap (category 3A) and is sold at the basic price of scrap metal.
However, more valuable components are hidden inside. The evaporator and condenser grill are often made of steel with an anti-corrosion coating, but the heat exchanger tubes can be copper or aluminum. Copper It costs several times more than ferrous metal, so its removal is economically justified if you have access to suitable cutting equipment.
The back of the refrigerator, often called the “grill,” is a steel coil painted with black enamel. In older models, the tubes could be made of steel, while in new ones, aluminum or steel is more common. The distinction between these metals is important: steel is magnetic, aluminum is not, and copper has a characteristic reddish tint when broken.
Compressor: where copper and steel are hidden
The heart of the refrigerator - the compressor - is the heaviest and most complex unit, containing a significant amount of both ferrous and non-ferrous metal. When disassembled, one compressor can yield from 1 to 2 kg of pure copper (motor windings) and about 5-7 kg of high-quality steel (housing, valves, plates).
The compressor housing is made of durable steel, often with an enamel coating, which makes it an excellent source of ferrous scrap. However, the main value is hidden inside: the electric motor is wound copper wirewhich, after stripping and burning (which is strictly prohibited by environmental regulations) or mechanical stripping, brings maximum profit.
Independent disassembly of the compressor requires special tools, such as an angle grinder (grinder) or a powerful hacksaw for metal, since the body is welded hermetically. At collection points, whole compressors are often accepted at the price of ferrous scrap with a premium, but not at the price of copper, so the decision on deep processing depends on your capabilities.
⚠️ Attention: Inside the compressor there is technical oil, which is a hazardous waste. When opening the unit, it is necessary to provide a container to collect the oil and dispose of it in accordance with environmental standards, without pouring it into the ground or sewer.
Table: Approximate yield of metal from refrigerators of different types
For clarity, we present data on the average content of metals depending on the type of refrigeration equipment. These figures are averages, since manufacturers are constantly changing designs, but they give a good idea of the proportions.
| Refrigerator type | Total weight (kg) | Ferrous metal (kg) | Non-ferrous metal (kg) | Other (plastic, insulation) |
|---|---|---|---|---|
| Small (single-chamber) | 35-45 | 20-25 | 1.5-2.5 | 10-15 |
| Medium (two-chamber) | 60-75 | 40-50 | 3-4.5 | 15-20 |
| Large (Side-by-Side) | 90-120 | 65-80 | 5-7 | 25-35 |
| Soviet (300l+) | 80-100 | 60-75 | 4-6 | 15-20 |
As can be seen from the table, the share of ferrous metal remains dominant in all categories. However, in absolute numbers, large models contain significantly more useful raw materials. Soviet refrigerators they are often heavier than modern analogues of the same volume due to the use of thicker metal and the absence of foam composites in some components.
Why may the weight differ from the table?
Weight depends on the thickness of the walls, the presence of ice inside (if not defrosted), the number of glass shelves and attachments. Also, modern models may contain more plastic in the interior, which reduces the percentage of metal.
Economic feasibility of disassembly
Is it worth spending time on disassembling the refrigerator yourself? The answer depends on current scrap prices and your labor costs. By handing over the entire refrigerator, you receive money only for black scrap, often with a deduction of 20-30% for “non-metallic inclusions”. By disassembling the unit, you can sell copper and aluminum separately at higher prices.
However, the disassembly process is labor-intensive and requires tools: grinders, wire cutters, screwdrivers, possibly welding or a powerful vice. If you rent out 1-2 refrigerators, the difference in price may not cover the cost of your time and tool depreciation. It’s a different matter if we are talking about regular disposal or a batch of equipment.
In addition, it is important to consider logistics. A disassembled refrigerator takes up less space during transportation, but requires packaging of different fractions of metal. Compressed case at the collection point they can be accepted more readily than a bulky whole box, as this facilitates their further processing.

Environmental aspects and disposal of insulation
When disassembling a refrigerator, a significant amount of waste is generated that is not metal. The internal space between the walls is filled with polyurethane foam, which in older models could contain freon, which destroys the ozone layer. Modern insulators are safer, but still require proper disposal.
Plastic elements, rubber seals and glass shelves should also not be thrown into a common container. Glass is recyclable, and some types of plastic can be taken to special points. Ignoring these rules negates the environmental sense of scrapping equipment.
Refrigerantsremaining in the system must be pumped out by specialists. Release of freon into the atmosphere is illegal and harmful. Professional recycling centers have equipment to safely collect gases, so handing over an entire refrigerator to a specialized organization is often a more environmentally friendly choice than makeshift dismantling in the garage.
⚠️ Attention: Burning insulation (polyurethane foam) to release metal is strictly prohibited. When burned, toxic substances are released that are hazardous to health and the environment. Use mechanical cleaning methods.
FAQ: Frequently asked questions
Is it possible to return a refrigerator for free?
In many cities there are programs for recycling household appliances that allow you to return a refrigerator for free, especially when buying a new model in a store (trade-in service). Also, some metal collection points can pick up the refrigerator themselves if its weight exceeds a certain norm, but in this case you will most likely not be paid anything.
Does the brand of the refrigerator affect the amount of ferrous metal?
Yes, it does indirectly. European and American brands (Liebherr, Bosch, Whirlpool) often use thicker metal for their cases compared to some budget Asian models. Soviet refrigerators are traditionally heavier due to the design and materials popular in the era of their production.
What to do with tubes if you don’t know whether they are copper or aluminum?
Perform a simple test: aluminum is not magnetic and is very light; when struck, it makes a dull sound. Copper is also not magnetic, but it is much heavier and has a reddish color when cut. Steel is magnetic. If the tube is coated with paint, scrape a small area to check the color and use a magnet.
Approximately how much can you earn on one refrigerator?
The amount depends on prices in your area. For black scrap (hull) you can get a nominal 300-500 rubles. For separated copper (from the compressor and pipes) - another 500-1000 rubles. The total amount rarely exceeds 1500-2000 rubles per unit of equipment, if you do not take into account the cost of time and labor.
