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.

Nanoperm Alloys
Although a relatively recent discovery, nanocrystalline materials are a well studied group of materials which have some specific magnetic applications whilst exhibiting some useful property characteristics also.
Due to a very fine distribution of crystalline grains within the amorphous matrix nanocrystalline alloys display excellent soft magnetic properties.
