Ni is the basis.
According to GOST 19241-80 the sum of the mass fractions of nickel and cobalt is ≥ 99.70%. In the alloy NMg0.1, the mass fraction of magnesium is allowed up to 0.15%, silicon - up to 0.020%, sulfur - up to 0.0050%. In the alloy obtained by vacuum melting, the mass fraction of zinc should be ≤ 0.0020%, the mass fraction of tin, lead, cadmium, arsenic, antimony, bismuth and phosphorus ≤ 0.0010% of each element (in this case the alloy is designated as HM0, 1c). In the alloy of vacuum smelting, the mass fraction of zinc is allowed to not exceed 0.0040%.
