Product Description

1. Alnico permanent magnets were developed in the ***0s and were the first Real performance permanent magnets. They are made primarily from aluminum, nickel, cobalt, copper, iron and sometimes titanium.

2. They can be either cast or sintered.

3. Cast Alnico

Cast alnico is melted and poured into a mold. 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 maximum magnetization and allows a higher gauss level. A cast magnet that is not heat-treated in a magnetic field is called isotropic. After heat treatment and cooling, the material can be ground to specific tolerances and then magnetized.

5. Sintered Alnico

Sintered alnico is made from a powdered mixture of ingredients that are pressed into a die under tons of pressure, sintered in a hydrogen atmosphere and then cooled either within a magnetic field or without (anisotropic vs. isotropic).
