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.

Product  Description

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 magnet is made by casting or sintering process, so it can be made into horseshoe and other complex shapes, which other magnetic materials can not do.

Alnico Magnet Properties

The advantages of aluminum nickel cobalt magnets are high remanence (up to 1.35T) and low temperature coefficient. When the temperature coefficient is -0.02%/℃, the maximum operating temperature can reach around 520 ℃. The disadvantage is that the coercive force is very low (usually less than 160kA/m) and the demagnetization curve is nonlinear. Therefore, although aluminum nickel cobalt magnets are easily magnetized, they are also easily demagnetized.
