Chrome Core® 12-FM

Chrome Core® 12-FM is in a family of controlled chemistry, chromium-iron alloys which are candidates for use in magnetic components where corrosion resistance superior to pure iron, low carbon steel, and silicon-iron alloys is desired without the substantial decrease in saturation induction associated with 18% Cr ferritic stainless steels. Each chrome level is available in both a standard and a free-machining grade. Ideal for applications of electro-mechanical devices requiring some degree of corrosion resistance, either in service or for extended shelf life without the need for protective coatings.
