Product Description
Precision Alloys:

Precision Alloys have special physical and mechanical properties, and are extensively applied in the key elements and devices of precision motor, electric appliance, instruments and meters, telecommunication equipments, and precision machines.

According to the application and specialties, precision alloys are split into magnetically hard alloy, magnetically soft alloy, elastic alloy, expansion alloy, thermo bimetal, resistance alloy, thermocouple alloy, electric conduction alloy, electric contact alloy, shape memory alloy, superconducting alloy and so on.

Soft Magnetic Alloy
1. Description
Soft Magnetic Alloy is one kind of alloy with high permeability  and low coercivity in weak magnetic field. This kind of alloy is widely used in radio electronics industry, precision instruments, remote control and automatic control system, generally, it is mainly used in energy conversion and information processing.
