CAST ALNICO
Cast alnico is melted and poured into a mould. Once solidified, the material is rough ground and then heat - treated and cooled, sometimes in a magnetic field.
When treated in the presence of a magnetic field, the magnet is called anisotropic. This orients the material to take on a maximum magnetization and allows a higher gauss level.

SINTERED ALNICO
Sintered Alnico is made from a powered mixture of ingredients that are pressed into a die under a tons of pressure, sintered in a hydrogen atmosphere and then cooled either within a magnetic field or without.
