Alloy MNC18-27
Designation
Description
Alloy MNC18−27 used: for the manufacture of semi-finished products (sheets, strips, tapes, long steel and structural shapes, pipe and wire); gorjacheotsinkovannyj parts; cases for watches.
Note
According to GOST 28873−90 alloy MNC18−27 should be removed from the production
The alloy has good spring properties.
Standards
Chemical composition
Cu is the basis.
According to GOST 492-2006, the total mass fraction of impurities is ≤ 0.60%. 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.
