General provisions of GOST 859−2014
GOST 859−2014 sets requirements for the chemical composition of high-purity cathode copper. The data are given in the table:
|Group index||Elements in the group||The limiting percentage of impurities,|
|Cu = 99.99%||Cu = 99.97%||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|
|5||Tin, nickel, iron, silicon, zinc, cobalt||0,0020||0,0020||0,0030|
The content of bound oxygen in the M00k grade is not allowed, and for copper grades M0k and M1k is limited by a limit of 0.015 and 0.020%, respectively. The composition and content of impurities in cast and deformed brands M0, M1, M2 and M3 is determined in a similar way. Supplier Evek GmbH offers to buy copper rental of domestic and foreign production at an affordable price in a wide range. We will ensure the delivery of products to any point of the continent.

Correspondence of Russian and foreign brands of copper
According to the technical standards ISO 1190−1: 1982 the following list of analogues is established:
The percentage of bound oxygen of tellurium and selenium is limited in M00b copper. Copper grades M1 and M1p, intended for use in the electrical industry, is indexed by the letter E, which is shown at the end of the main designation of the metal. In brands M2 and M3, by agreement with the customer’s representatives, the percentage of bound oxygen is allowed to exceed. In grades M2 and M3, the percentage of silver and zinc is not standardized.
