Hot Sale Sintered Alnico Magnet With High Resistance
Demagnetization
General Description:
Alnico magnets, composed of primarily aluminum (Al), nickel (Ni),
and cobalt (Co), were developed in the 1940's. This class of magnet
remains a preferred material because of its excellent temperature
stability, high magnetic flux density, and resistance to corrosion.
Alnico magnets are manufactured through a casting or sintering
process. The casting process allows for the magnet to be
manufactured into intricate and complex shapes. Sintered Alnico is
made from a powdered mixture of ingredients that are pressed into a
die under tons of pressure. The Sintering process allows for the
magnets to be manufactured to tighter tolerances and higher
mechanical strength.
Possessing the following characteristics:
1. High residual induction
2. Excellent temperature stability
3. Good corrosion resistance
4. Wide range of complex shapes and sizes available
5. Can be plated or coated
6. Easy of magnetization
7. High field strengths at medium prices
8. Lower initial tooling cost
9. Alnico magnets are widely used in motor, sensor,meter,telephone
and speaker, teaching, detector, MRI, holding system,etc.
