Precision alloys are metal materials with special physical properties (such as magnetic, electrical, thermal and other properties). The vast majority of precision alloys are based on ferrous metals, and only a few are based on non-ferrous metals. Usually include magnetic alloys (see magnetic materials), elastic alloys, expansion alloys, thermal bimetals, electrical alloys, hydrogen storage alloys (see hydrogen storage materials), shape memory alloys, magnetostrictive alloys (see magnetostrictive materials), etc.
Soft magnetic alloys are a class of alloys with high permeability and low coercivity in weak magnetic fields. According to the different elements that make up the alloy, it can be divided into electromagnetic pure iron (industrial pure iron), iron-silicon alloy, iron-nickel alloy, iron-aluminum alloy, iron-silicon-aluminum alloy and iron-cobalt alloy, etc.1J06,1J12,1J17,1J18,1J22,1J30,1J36,1J38,1J46,1J50,1J51,1J54,1J76,1J77,1J79,1J80,1J85,1J87

Permanent magnet alloy not only has high hardness and mechanical properties, but also has strong anti-demagnetization ability, high coercivity value (greater than 20kA/m), magnetic "hard" and other characteristics, so it is also called hard magnetic alloy.2J04,2J07,2J09,2J10,2J31,2J53,2J84,2J85
Elastic alloys include high elastic alloys and constant elastic alloys. It is used to make elastic elements such as elastic sensitive elements, energy storage elements and frequency elements in precision instruments.3J01,3J21,3J53
Expansion alloys(Invar Alloy) are divided into Kovar alloys, ceramic sealing alloys, low expansion alloys, and constant expansion alloys. Widely used in electronic industry, precision measuring tools, precision instruments and low temperature engineering and other fields.4J28,4J29,4J32,4J33,4J36,4J40,4J42,4J50

Precision alloys with nickel, chromium, aluminum and iron as the main components, the resistivity is about three times higher than that of manganese copper, and has a lower temperature coefficient of resistance and low thermal potential to copper, with good long-term resistance stability and resistance. Oxidation properties.
It is suitable for making precision resistance elements in various measuring instruments and meters, making precision micro-resistance elements and strain gauges.6J10,6J15,6J20,6J22,6J23,6J24
