Good magnetic reach out for capture of contaminants
- Can be used effectively up to 1000° F
- Separation capabilities are similar to ceramic
Composition and Manufacturing Process:
Two types of Alnico are available. One is cast and the other is sintered. Cast is poured in a molten form into a mold. Sintered is a powdered mixture that is dry pressed. Alnico consists of aluminum, nickel, cobalt, copper, iron, and sometimes titanium. While being cast or sintered sometimes a magnetic field is applied. When subjected to the magnetic field this magnet is called anisotropic. When no magnetic field is applied this is called isotropic. After cooling, the magnets are ground to the desired dimension and magnetized.
