Description

Alloy MNC15−20 used: for the manufacture of semi-finished products (strips, sheets, strips, pipes, rods, wire and profile rolling); relay springs; parts for electrical engineering; parts, get a deep hood; Cutlery; art products; drawn (6−15 mm) and rolled (32−40 mm) bars for tank construction.

Note

The alloy has good spring properties.

Cu is the basis.
According to TU 48-21-84-72, GOST 492-2006, the total mass fraction of impurities is ≤ 0.90%. 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 tin.
