ALNiCo Block Magnet

ALNICO Block MAGNET

The composition of the metal ingredients, magnetic can also different, so use is also different. Aluminum nickel and cobalt permanent magnet there are three kinds of different production process: casting, sintering, binding [1]. The casting process can be processed into different sizes and shapes, compared with casting process, the size of the sintered products is limited to small, its blank product dimension tolerance is small, casting machinability is good. In the permanent magnetic material, casting aluminum nickel and cobalt permanent magnet has the lowest temperature coefficient is reversible, working temperature can be as high as 500 degrees Celsius above

Alnico is one of the first permanent magnetic materials developed. It is an alloy composed of aluminum, nickel, cobalt, iron and other trace metal elements.

The aluminum-nickel-cobalt permanent magnet was developed in the 1930s.

AlNiCo was the first permanent magnet to be developed. It is an alloy of aluminum, nickel, cobalt, iron and other trace metal elements.

The aluminum-nickel-cobalt permanent magnet was developed in the 1930s.

At that time, it had the best magnetic property and low temperature coefficient, so it was most widely used in permanent magnet motor.

After the 1960s, with the advent of ferrite permanent magnet and rare earth permanent magnet, the application of al-Ni-Co permanent magnet in motors was gradually replaced, with a decreasing proportion.
