Soft Magnetic Alloy : is a type of alloy with high permeability and low coercivity in a weak magnetic field. This type of alloy is widely used in the radio electronics industry, precision instrumentation, remote control and automatic control systems. Together, it is mainly used in two aspects: energy conversion and information processing. It is an important material in the national economy.
Grade: 1J50 (Permalloy), 1J79(Mumetal,HY-MU80), 1J85(Supermalloy),1J46
Standard: GBn 198-1988
Application: Most of the small transformers, pulse transformers, relays, transformers, magnetic amplifiers, electromagnetic clutches, chokes that are used for weak or medium magnetic fields Flow ring core and magnetic shield.
