Advantages of Alnico Magnets

1. Cast Alnico offers a near net shape. Cast alnico can be produced to complex shapes with complex magnetic patterns.
2. Alnico Br as high as NdFeB at room temperature.
3. Can be used up to 450-550 degrees C.
4. Least variation in magnetic output with temperature change of any magnetic material.
5. Can be cast in very large sizes.
