Alnico material can be sorted into Cast and Sintered type. Cast Alnico has a high magnetic capability and sintered is easy to machine into various shape. Alnico can work at 400degrees C and has a high rust-resistance, no need coating. This kind of magnet is mainly used in instruments and products that operate at high temperatures condition.

Main features:
1.Produce by casting or powder metallurgical techniques  
2. An alloy composed of matrix of Al-Ni-Fe-Co 
3.Very hard & brittle  
4. Poor resistance to demagnetization  
5. Produce good flux density at an reasonable cost  
6. Excellent stability over a wide temperature range
