Copper after silver is the best conductor of electricity. Copper M2 durable, ductile and malleable. It is resistant to corrosion in most atmospheres including marine and industrial environments. However, it is susceptible to corrosion in the active inorganic acids, solutions of Halogens, sulphides and ammonia.
High electrical and thermal conductivity is particularly valuable in the electrical industry. Copper M2 is characterized by high ductility and impact strength. The main areas of practical use: General engineering, electronics, manufacture of bus bars, automotive industry and household appliances.
The chemical composition of the mark M2 is governed by the technical requirements of GOST 859−2001. In addition to copper, allowed such impurities as iron, Nickel, sulfur, arsenic, lead, zinc, silver, bismuth, tin and antimony. Also allowed a minor content of the linked oxygen. The total percentage of impurities may not exceed 0.3%.
