Precision alloys are alloys of metals that are characterized by certain physical properties (elasticity, magnetization, thermal conductivity, heat transfer). Each such property of the metal is determined by the chemical composition of the alloy, its structure and the presence or absence of any harmful impurities. The composition of precision alloys, as the main elements may include nickel, cobalt, iron, niobium and others.
