The steel housing provides a safe place for the magnets embedded in it. Most pot magnets can be heated to temperatures up to 80°C without losing their magnetization
Aluminum nickel cobalt (AlNiCo) is the earliest developed permanent magnet material, which is an alloy composed of aluminum, nickel, cobalt, iron, and other trace metal elements. It has the best magnetic properties and a small temperature coefficient, making it the most widely and widely used in permanent magnet motors.
AlNiCo magnets provide high magnetic strength, energy, but low coercivity. They are more fragile than rare earth magnets, have excellent temperature stability. AlNiCo magnets usually do not require protective coatings or coatings because of their excellent corrosion resistance.
Samarium cobalt magnet is mainly made of Cobalt,Samarium and other rare earth elements.Its advantage is the maximum operating temperature up to 350 ° C and its good corrosion and oxidation resistance.Samarium cobalt magnets, therefore do not need to be coated.lt is widely used in motors, meters,sensors,detectors, engine, radar and other high-tech fields.
