Product Description
Alnico round magnets for Precision balance

Alnico permanent magnets were developed in the 1930's and were the first "Real" performance permanent magnets. They are made primarily from aluminum, nickel, cobalt, copper, iron and sometimes titanium. They can be either cast or sintered.

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.

Common Characteristics of Alnico magnets

1. Very temperature stable, great for high heat applications 
2. Wide range of working temperatures, up to 550ºC
3. May be ground to size 
4. Does not lend itself to conventional machining (hard and brittle) 
5. High residual induction and energy product compared to ceramic material 
6. Low coercive force compared to ceramic and rare earth materials (more subject to demagnetization)
