Copper is characterized by high conductivity of electric current.
This parameter determines the main area of its use: the production of pipes and cables, as well as high-vacuum equipment. For this reason, the cost of copper is significantly higher than the prices of other non-ferrous metals. In addition, the advantage is the environmental safety of raw materials. Copper products are entirely recyclable, and technical characteristics are not lost. The actual processing procedure is designed to save energy along with natural resources, since during smelting the consumption is less than 90% than when producing products, say, from ore. According to the latest statistics, a high proportion of industrial use of recycled copper products is known, namely 34% of the total. This amounts to about 25 million tons of raw materials. Products containing copper are characterized by a long life span - 2-100 years. Consequently, the share of scrap metal is quite high, and today the cost of 1 kilogram of copper scrap varies between 250-330 rubles.
Where can you find copper?
It is copper that is used in the manufacture of entire devices, in particular parts or their components, relevant in the following areas:
- Electrical engineering, mechanical engineering - motor windings, sets of subassemblies (bearings), conductive cables, various parts.
- Instrumentation - small elements of power supplies.
- Construction – tiles, gas and water supply and other engineering systems.
- Production of household appliances - refrigeration equipment, televisions, etc.
- Manufacturing of medical supplies – medical containers, device handles, surfaces.
- Shipbuilding - copper plating of ship components makes it possible to withstand the aggressive effects of sea water.
In addition, after recycling, scrap metal is used in art in the manufacture of forged figures, as well as household items (kitchen paraphernalia).
In a decent amount, it is just right to detect scrap containing copper in:
- products used in plumbing (angles, sockets, couplings, etc.);
- gas burners;
- faulty electrical appliances (copper hoses of heat exchangers of hoods, air conditioners, printed circuit boards);
- industrial recyclables (shavings, copper dust, scrap metal in the remains of pipes).
In turn, the pure alloy is used in the form of solder, as well as consumable raw materials for welding and cutting work with other metals, for example, cast iron. In the soldering action, copper is used to coat raw materials that are difficult to solder. In turn, copper plating leads to increased corrosion resistance.

What influences pricing: factors
In addition to the brand of secondary raw materials, the following factors influence the price of a kilogram of copper scrap:
- Scrap collection company. Large factories that purchase/process raw materials give a higher price, but do not accept scrap less than 1 ton.
- Valuation on the stock exchange. Quotes change daily, so companies adapt to national/international price criteria for metal purchases.
- Like any product, the cost per kilogram of copper directly depends on fluctuations in exchange rates. A rising dollar provokes an increase in the cost of raw materials.
Those wishing to sell copper at a profit should study the price list at the collection point. Preference should be given to a reputable dealer, even if he is a little less expensive. Often, small dealers, in order to attract a client, set a high tariff, although in reality they reduce it during the transaction, citing the poor quality of the metal. Thus, on official services, data on the price of a kilogram of copper is updated daily.
The price for copper scrap is higher with non-cash payment
Cash payments for metal cause a lot of trouble for suppliers. It is easier to buy copper scrap by bank transfer.
Nowadays, many large and honest producers of copper scrap suggest that regular scrap dealers should have a special bank card. They transfer money to this card for purchased copper scrap. There are special applications for smartphones that allow you to immediately check the receipt of money.
Are there any benefits to buying scrap metal?
As in any business, the goal is to generate income, and the area of recyclable materials is no exception. Receiving copper scrap can be a profitable business that does not require special investments. The organization's model is reduced to the purchase of metal, starting from a kilogram of copper. So, private individuals are asking a little less than the price at which they will rent it to a processing factory. The difference, after deducting transportation costs, will be income.
Before starting an activity, you need to select a suitable site so that there are no identical metal receiving points nearby. It is worth choosing a processing plant in advance where you will subsequently deliver your scrap.
The price may be higher when there is a significant volume of metal, since wholesale prices apply from 1 ton. Meanwhile, when paying by bank transfer, it is possible to get a high price, winning 10-15 rubles. from every kilogram. Buyers often remove the metal themselves, which is convenient and also saves on transportation costs. Thus, to answer the question of interest: “How much will they give per kilogram of copper?” It will be possible only taking into account all the above factors.
I tell you the secret of making money on nickel and copper
Inflation in Russia and the World has hit every person's budget in the gut. The suffering of the Russian people results in the profits of alcohol companies. But then a good-natured person appears who will share with you an idea on how to make money from metal.
While I was writing a post about Norilsk Nickel yesterday, a hitherto unknown insight came into my bright, bald head, which I will now share with you, my dears.
First of all, I would like to draw your attention to the quotes of metals: nickel and copper. Nickel price today:
$22,395 per ton of nickel. For ease of calculation, I convert it into the price of rubles per kilogram, assuming 1 $ = 75 rubles:
- 22395*75/1000 = 1680 r/kg (rounded up a bit)
Now let’s turn our attention to the copper quote today:
$9991 per ton of copper. To simplify the calculations, I will also display the price of 1 kg of copper in rubles, assuming 1 $ = 75 rubles:
- 9991*75/1000 = 750 RUR/kg (rounded up a bit)
And now that we, with great grief, have found out the price in rubles for 1 kilogram of nickel and copper, we can get to the point.
Yesterday, after processing this idea, I shared it with a well-known conspiracy theorist. I don’t see the point in mentioning his name, since everyone knows him. In general, he did not approve, rejecting the idea at the stage “there must be some nuance that ruins the whole idea,” but he did not leave any counterarguments.
I suggest you take a look at the subject of our study:
In front of you is 1 ruble from the Bank of Russia. Stamped since 1997. Coin weight 3.25 g. Material: copper-nickel alloy.
By now you should already be able to guess what we're going to talk about.
Let's assume for a moment that this coin was stamped not from cupro-nickel alloy, but from copper. In 1 kg of ruble coins there should be, taking into account the weight of one 3.25 grams:
- 1000/3.25 = 308 pcs. (rounded up a bit)
It turns out that we can exchange 308 rubles for 308 pieces of ruble coins, with a total weight of 1 kg of “copper”.
Now we return to the price of copper, it is equal to 750 rubles/kg, and we just “exchanged” this kilogram for 308 rubles. Are you smart?
Now you need to pay attention that ruble coins are made not from pure copper, but from a copper-nickel alloy. And nickel will be more than 2 times more expensive than copper. However, as a rule, the amount of nickel in such an alloy does not exceed 20%. But I don’t know the exact amount of it in the alloy of ruble coins. Therefore, it is convenient to take the price of pure copper as a standard.
The nuances of making money
But of course, not all coins fit the above scheme. The fact is that although previously rubles were stamped from a copper-nickel alloy, now this alloy has been replaced by steel with nickel galvanization. Those. of no particular value.
How to determine the right metal
I present to you a table of stamping of Russian coins since 1997
I made a slight truncation of the table, since other years are not interesting.
Yellow arrows point to coins of interest to us. The only thing I’ll add is that coins marked in red cost much more than their metal and face value, but that’s not what the post is about.
How can we get the rubles we need out of circulation? We need a magnet that will select coins that we don’t like from a heap, or rather those that are magnetic because they are made of steel.
The picture shows: a magnetic ruble (left) and a non-magnetic one (right). Those. from 1997 to 2005 they were made of copper-nickel alloy, and from 2007 to today they were made of steel. in 2006, coins of both types were minted.
All that remains is to get (buy, exchange) money for coins and, using a magnet, weed out the ones you need, and put the rest back into circulation.
What other coins can you turn into money?
The same can be done with coins of 2 and 5 rubles, but their weight (5.1g and 6.45g, respectively) will not be a multiple of that of a ruble coin, so the exhaust will be less. And in the case of 5-ruble ones, without it at all. (155 coins per kilogram = 775 nominal rubles, with a copper price of 750 rubles/kg).
There are also kopeck coins. We may not be interested in 1 and 5 kopecks, since they have always been made of steel, but 10 and 50 kopecks will be very interesting. They were stamped from brass. Now let’s calculate the amount per 1 kg a little:
- 10 kopecks weigh 1.95 grams -> in 1 kg there will be 513 pieces (rounded up a little)
- 50 kopecks weigh 2.9 grams -> 1 kg will be 345 pieces (rounded up a little)
the price will be:
- 10-kopeck coins in 1 kg = 51.3 rubles
- 50-kopeck coins in 1 kg = 173 rubles
On the black market of any scrap metal acceptor, the price of brass varies depending on the amount of weight handed over at the same time and starts somewhere from 325 rubles and creeps up.
This all means that you can buy 1 ton of 10-kopeck coins for 51,300 rubles, and sell them as scrap brass for at least 325,000 rubles.
Why didn't I do this myself? Because I'm a lazy ass.
What is copper "mix"?
This raw material consists of a mixture of copper products, uninsulated production residues, clogging and ferrous scrap. Most often it is supplied in the form of household scrap, or a mixture of raw materials from retail collection points. Traces of tinning, traces of soldering, a small percentage of insulation, construction waste, paintwork (varnishes, paints, chrome plating) are allowed. The total percentage of blockage should not be more than 3-5%. If raw materials are supplied of insufficient quality, the receiving point reserves the right to apply a clogging factor or refuse to accept the metal.
