I believe that many friends are very familiar with magnets, magnets have a lot of work, is a mutual repulsion and mutual attraction of the object. The magnet is composed of iron, nickel nie, cobalt gu, which has its own magnetic distance, and the internal structure is arranged in the same direction, one end of the North Pole and one end of the South Pole. So there are a lot of objects in nature, so why aren't they magnetic?

1. Ndfeb magnets are modern permanent magnets with strong magnetic properties and are widely used. It is mainly used in electroacoustic, permanent magnet motor, communication, automotive electronics, magnetic machinery, aerospace, computer, household appliances, medical equipment, office automation, toys, packaging boxes, leather products, magnetic jewelry and other fields.

According to the different production process, aluminum nickel cobalt magnets can be divided into castings and sintering, the mechanical strength of the sintering is higher than the casting, the processed products are relatively simple, and it is easier to produce small and irregular products.

Shaped magnet itself is not a whole from the main components of neodymium, iron, boron and other raw materials after grinding mixed sintering, shaped magnet is called shaped is its product shape is not very conventional.

Aluminum nickel cobalt magnet is an alloy made of aluminum, nickel, cobalt, copper, iron and other materials. According to the different processing technology, it is divided into cast aluminum nickel cobalt and sintered aluminum nickel cobalt two kinds.
