Hard Magnetic alloys: Part One

The process and material selection for permanent magnetization of magnetically hard materials has progressed over the years. Magnets steels, which are now largely obsolete, have been replaced in the most part by ternary alloys of iron, cobalt, and molybdenum, or tungsten.
According to international classification it is possible to see a break down on the hard magnetic materials according to the three main categories.
