Soft Magnetic Alloy for Shielding and permalloy core

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.
