Sex energy: forming alloys with refractory materials. Cobalt has ferromagnetism and ductility, and its mechanical properties are better than that of iron.
Metal cobalt is mainly used to make alloys. It is an important raw material for the manufacture of heat-resistant alloys, hard alloys, antiseptic alloys, magnetic alloys and various cobalt salts. It is widely used in the aviation, aerospace, electrical, mechanical manufacturing, chemical and ceramic industries.
Path: Gaochun is an important material for the preparation of magnetic recording media, magnetic recording heads, photoelectric devices and magnetic sensors and integrated circuits. It can also be used as a semiconductor thin film material.
