Samarium Cobalt permanent magnet is widely used second generation high energy material. Using Samarium and Cobalt as its rare earth element, it exhibits high magnetic performance characteristics in energy product and coercive force. There are two compositions of magnets in this family: Sm1Co5 and Sm2Co17. The highest commercially available energy products of Sm2Co 17 are in the 30MGOe range. Al2O3 ceramics: high alumina content, compact structure, special properties, it is called special ceramics. The Al2O3. ceramic material is a close-packed hexagonal structure composed of oxygen ions, and the aluminum ions are filled in two-thirds of the octahedral gap, which is the same stable α-Al2O3 structure as natural corundum, so the ceramic has a high melting point and high Hardness and excellent wear resistance. Ceramic patch hardness ≥ HRA85, second only to the hardness of diamond, and the surface smooth friction coefficient is small, the wear resistance is very good, especially in high temperature oxidizing medium or corrosive medium, the performance of ceramic patch material compared with other metal materials More superior.
