Description
M2 copper is used : for the production of high-quality semi-finished products and copper-based alloys processed by pressure; for the manufacture of cryogenic equipment products; round drawn thin-walled pipes; drawn rectangular pipes intended for the manufacture of waveguides; drawn capillary tubes used in apparatus and instrument making and refrigeration engineering; cold-rolled foil and strip, cold-rolled and hot-rolled sheets and plates for general purposes; radiator tapes intended for the manufacture of cooling tubes and radiator plates.
Note
M2 copper is obtained by fire refining and melting of copper waste and scrap.
What GOST standards for copper scrap exist?
Pure copper is not used for the manufacture of products. It is used as ready-made alloys, the compositions of which are regulated by generally accepted standards. In Russia, the main regulation is GOST 859-2001. He describes in detail the grades and compositions of copper alloys, as well as the permissible areas of their use.
Since copper is a non-ferrous metal with unique physical and chemical properties, it is actively used in industry, production, construction and domestic conditions. There is also a separate classification of copper scrap, which is purchased on the secondary market. Our company accepts copper at a price of 340 rubles per kg.
Details about the conditions and costs of specific types of copper alloys are presented on the website.

Copper grades - characteristics and markings with explanation
The designation of metal alloys based on the use of copper begins with the letter “M”. This is followed by a number characterizing the mass fraction of copper in the composition (alloy class).
So, when the metal is designated “M3”, the amount of the main element reaches 99.5%, and “M00” - 99.96%. Also, the marking usually indicates additional letters informing about the method of producing the alloy.
Methods for creating copper alloys are divided into:
- cathode (denoted by the letter “k”);
- deoxidation with low phosphorus content (“p”);
- without deoxidizing additives – oxygen-free (“b”);
- deoxidation with a large amount of phosphorus (“f”).
The general marking of alloys looks like “M1r”. However, the production method is not always indicated or is not used at all if the processes of hydrolysis, pyrometallurgy or hydrometallurgy were used. In such cases, the designation is limited to the mass fraction. Without taking into account alloy modifications, copper is classified into four main grades:
- M0. The highest class of copper alloys, containing about 99.93-99.99% copper. Sometimes, to improve the physicochemical properties, silver is added to the composition and the percentage of the main element is indicated as copper + silver as a single main component. M0 is the purest copper alloy, which is used for the manufacture of conductive products (power cables, conductors in electronics, household wires, and so on).
- M1. An alloy more common in modern conditions. It is also used to make electrical products with less stringent quality requirements. M1 is also used for the production of rolled metal products, welding electrodes, wire, and so on. The percentage of copper content in M1 is 99.9%.
- M2. This brand is widely used in the production of products requiring high pressure processing. M2 is a less ductile metal, since it contains 99.7% copper. The alloy is often used for the manufacture of cryogenic equipment parts.
- M3. The grade belongs to alloys with the lowest copper content (99.5%). Such metals contain large amounts of impurities and are often obtained from the recycling of copper products. M3 alloy is used to manufacture parts by rolling.
Individual modifications characterize the type and number of additional elements. Detailed information about brands is specified in GOST 859-2001.
Impurities in copper alloys
Since copper practically does not exist in its pure form, the metal already contains other substances. During the manufacturing process, other elements are added to enhance the physical and chemical properties of the alloy and give it unique characteristics. The composition usually contains:
- bismuth (0.0005-0.003%);
- iron (0.001-0.05%);
- nickel (up to 0.2%);
- zinc (0.001-0.005%);
- tin and antimony (up to 0.05%);
- arsenic (no more than 0.01%);
- lead (up to 0.05%);
- sulfur (0.002-0.01%);
- oxygen (0.001-0.08%) and others.
If silver is separately indicated in the composition to increase electrical conductivity, the percentage of content does not exceed 0.002.
Standards for Copper Alloys
In our country, there are a large number of regulations used as basic standards that are mandatory when working with copper. The main regulations include:
- GOST 859-2014 “Copper. Stamps."
- GOST 193-2015 “Copper ingots. Technical conditions".
There are specific regulations for certain types of alloys (bronze, brass). The standards are updated periodically.
GOST 859-2001
Previously, this regulation was the main one for copper and copper alloys. However, in 2014 it was replaced by GOST 859-2014. It spells out the main brands, taking into account modern innovations and additional requirements for production processes, production methods, and so on.

What associations do you have with the word metal? People with a narrow worldview will say that there is nothing special about this word, but most associate it primarily with reliability and, for some reason, with a hard blow) Now it’s even difficult to imagine how humanity used to get by with such a hardy and almost indestructible substance . But since now all industries are closely connected with metal, namely products made from it, we need a company that will sell rolled metal at affordable prices. One of such useful and responsible companies is Metal rolling in St. Petersburg.
Copper sheets are made from copper grades M1, M1R, M2, M2R, M3, M3R in accordance with GOST 495-92, the chemical composition of which corresponds to GOST 859.
Among the huge assortment of varieties of products, you can choose the most suitable one for yourself (copper sheet, reinforcing strands, corners, etc.) for you and by purchasing you can be confident in its strength, because it is strength that determines 100% of the quality of any metal.
Technical characteristics of copper sheet
Each metal alloy has its own individual characteristics, which determine their use and service life. Having decided on the purpose, you can safely choose the one that suits you, taking into account all the features. For example, a copper sheet is very easy to use, but titanium sheets are distinguished by good strength and require good skill in using it.
Copper sheet weight
Almost every product leaving the factory has a standard weight for easy transportation and packaging. Just imagine what would happen if every metal was produced in any size. It would make your life very difficult.

Copper m1 m2 m3 difference
Due to their properties, various grades of copper are very popular in the industrial environment. This metal is good because it is flexible and, regardless of the operating environment, with the exception of exposure to sulfur dioxide and ammonia, it is resistant to corrosion.
The external distinctive feature of copper is its pink-red color. Depending on the purity, copper is divided into types with the technical designations M1, M2, M3. This metal comes into production in the form of wire, sheets, pipes, and rods.
This is due to different application situations.
Schedule
Based on its composition, copper is divided into oxygen-free and deoxidized; the symbol is M0 and M1, respectively. Oxygen-free is used in the manufacture of parts for electrical, electronic, and electrovacuum industrial products. O2 in oxygen-free brands is no more than 0.001%, and in deoxidized ones - 0.01%.
The breakdown of copper grades is presented in the table:
