Is alnico magnet strong magnetic?

The picture above shows the picture of alnico magnet. Because of its good antirust property, electroplating is not required. Aluminum nickel cobalt can be produced in cylindrical shape, ring shape, cuboid shape, flat shape, tile shape and horseshoe shape.
At present, among the magnet materials used in the market, the strongest one is NdFeB magnet, which can withstand about 220 ° at most, followed by samarium cobalt, which can withstand 350 ° at most. Aluminum nickel cobalt and ferrite are very weak in magnetism, not strong in magnetism, but have good temperature resistance. This is also a rule of magnets. Magnetic force is inversely proportional to temperature resistance.
