Technical characteristics

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.

Relevance

High electrical and thermal conductivity is particularly valuable in the electrical industry. M3 copper 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.
