Alloy MN25
Designation
Description
MN25 alloy used: for the manufacture of semi-finished products (strips, sheets, strips, rods, pipes); coins; decorative items and consumer goods.
Standards
Chemical composition
Cu is the basis.
According to GOST 492-2006, the total mass fraction of impurities is ≤ 1.30%. In the alloy, the mass fraction of cobalt ≤ 0.50% is allowed due to the mass fraction of Ni + Co, which is not taken into account in the total amount of impurities. The mass fraction of cobalt exceeding 0.50% is taken into account in the total amount of impurities. In the alloy, in agreement with the consumer, it is possible to determine the mass fraction of silicon, magnesium, arsenic, bismuth, phosphorus, tin, antimony.
