Precision resistance alloys refer to alloys with low absolute values of resistance temperature coefficient and copper thermal electromotive force, and good stability, mainly characterized by resistance value characteristics. These types of alloys are mostly nickel based alloys. These types of alloys have specific electrical resistance characteristics. For example, 6J20 alloy has a high resistivity and a low resistance temperature coefficient, making it suitable for making various measuring instruments, meters, and other resistance components; 6J22 alloy has a low resistance temperature coefficient and small thermoelectric electromotive force on copper, making it suitable for making precision resistance components in various measuring instruments and meters. These types of alloys are mostly supplied in fine wire form. The main requirements are to inspect the resistance value per meter, average resistance temperature coefficient, coaxial resistance change per meter, average thermoelectric electromotive force on copper, paint film performance, etc
Function of testing report:
