Corrosion Resistant Magnetic Alloys for Alternate Fuels and Other Applications

Automotive technologies such as fuel injection, anti-lock braking systems and automatically adjusting suspension systems have created a need for soft magnetic alloys having good corrosion resistance and fabrication characteristics, but with higher saturation flux density (B_s) and more consistent magnetic performance than ferritic stainless steels.

This paper will describe the development of a family of controlled chemistry Chrome Core™ * alloys specifically designed for use in magnetic components where corrosion resistance substantially superior to that of pure iron, low carbon steel and silicon-iron alloys is required without the substantial decrease in saturation flux density and inconsistent magnetic response associated with conventional ferritic stainless steel.
