Abstract
The magnetic metal composition of a Co-based alloy includes additives to produce an amorphous condition in the alloy and also includes amounts of Rh to increase the corrosion resistance of the alloy. By adding the amorphous-producing materials and selected amounts of Rh, the corrosion resistance of the resulting Co-based alloys has been found to be considerably improved over that of the base amorphous Co alloy without rhodium.
