Barium ferrite ferrite has better packing properties. BaFe can be reduced to a smaller size and higher packing density because of its circular structure and can be stacked better. Barium ferrite Barium ferrite, abbreviated BaFe, BaM, is the chemical compound with the formula BaFeO. This and related ferrite materials are components in magnetic stripe cards and loudspeaker magnets. BaFe is described as Ba(Fe)(O). The Fe centers are ferromagnetically coupled. This area of technology is usually considered to be an application of the related fields of materials science and solid state chemistry. Barium ferrite is a highly magnetic material, has a high packing
Silver steel the annealed state it has a hardness of 27 HRC. It can be hardened to 64 HRC. The European/Werkstoff equivalent is 1.2210 / 115CrV3, which also includes some vanadium. Silver steel Silver steel is common tool steel that is supplied as a centerless ground round bar (with tolerances similar to that of drill bit). The name comes from the highly polished appearance of the rods; there is no silver in the alloy. Amongst other applications, it has been widely used to make such things as punches, engravers, screwdrivers. Sheffield silver steel is used in France as a blade steel for
