Precision alloy
Precision alloys are metal alloy materials with special physical properties, widely used in electrical and electronic, consumer electronics, precision instrumentation, information communication, metal sealing. automatic control, automobile, aviation, nuclear power and many other fields, is the core key materials.
These alloys have the properties of magnetism, electricity, expansion, resistance, etc., and are divided into seven categories according to their different physical properties, including soft magnetic alloys, permanent magnetic alloys, elastic alloys, expansion alloys, resistance alloys and so on. The classification of precision alloys also includes thermal bimetallic alloys, electrical alloys, hydrogen storage alloys, shape memory alloys, magnetostrictive alloys and so on.
In practical application, some new alloys are also classified into the category of precision alloys, such as damping and vibration damping alloys, stealth alloys, magnetic recording alloys, superconducting alloys, microcrystalline Amorphous alloys, etc. The vast majority of precision alloys are based on ferrous metals, and a few are based on non-ferrous metals, which require a strict range of chemical compositions and special melting and heat treatment processes to ensure that they have certain physical properties and physical and mechanical properties.
