Electromagnetic Induction High Resistivity Anticorrosion Soft Magnetic FeCr Alloy

Anticorrosion Soft Magnetic Alloy(GB/T14986-1994)

Usage: Electromagnetic components used in oxidation environment and hydrazine environment.

1. This material is anticorrosion soft magnetic FeCr alloy. 

2. With its high magnetic induction, low coercive force as well as high resistivity, it is mainly used as megnetic material in all kinds of electromagnetically operated valves in contact with corrosive medium as well as in the electro-hydraulic valve of aeroengine.
