Copper ingots could be different grades for different usage:

• М0 - conductor of heat and electricity and further manufacturing of high quality alloys

• М1 – current-carrying conductor, mill products, high quality bronze without tin content, for cryogenic technique manufacturing

• М2 - for cryogenic technique manufacturing, manufacturing of alloys that are based on copper content, semi finished products manufacturing

• М3 – for the further pressure treatment, getting casting alloy, cryogenic technique manufacturing
