Technical characteristics

The chemical composition of the primary (cathode) of copper, characterized by high chemical purity, is governed by the technical requirements of GOST 859−2014:

Group of copper Elements contained as impurities The greatest percentage concentration of impurities, % in the finished product by brand copper
M00k M0k M1K
Cu = 99,99% Cu = 99.97% of Cu = 99,95%
1 Bismuth, selenium, tellurium 0,0003 0,0005 0,001
2 Chromium, manganese, antimony, cadmium, arsenic, phosphorus 0,0015 0,003 0,006
3 Lead 0,0005 0,001 0,003
4 Sulfur 0,0015 0,002 0,003
5 Tin, Nickel, iron, silicon, zinc, cobalt 0,0020 0,0020 0,0030
6 Silver 0,0020 0,0020 0,0030

Similar requirements on chemical composition are applied to the deformed copper grades M1, M2 and M3. The relevant requirements are contained in GOST 15527−90.

Copper alloys

Copper alloys — bronze and brass are widely used for the manufacture of products which, when their applications require high performance of its electric conductivity, thermal conductivity and resistance to corrosion phenomena.

Brass

Brass are an alloy of copper and zinc. The presence of zinc increases the mechanical strength of the alloy also increases the hardness and elongation. Various grades of brass are manufactured with the purpose of giving the alloy good properties of formability or machinability. Depending on the production method and heat treatment of brass is divided into soft, semi-solid and solid. Marks and determines the chemical composition of brass GOST 15527−2004 (deformable) and GOST 17711−93 (foundries).

Bronze

Bronze is an alloy of copper with any other metal except zinc. The bronze used for the production of corrosion-resistant parts exposed to abrasive or corrosive-mechanical wear. The composition and properties of bronze are regulated by GOST 613−79 and GOST 493−79 (cast bronze), GOST 18175−78 and GOST 5017−74 (wrought bronze).
