Description
Silicon carbide is a very hard ceramic material with the following properties and product advantages:
1. High hardness: silicon carbide hardness is second only to diamond and cubic boron nitride, can be used to manufacture high wear resistance, high strength parts.
2. High temperature resistance: silicon carbide has extremely high temperature resistance, can be used for a long time above 1200℃. Therefore, it is widely used in high temperature process.
3 corrosion resistance: silicon carbide has good corrosion resistance to acid, alkali and other chemicals, and can replace stainless steel and other materials in some special environments.
4 low density: the density of silicon carbide is low, the proportion is only about one third of iron, so that it has been widely used in aerospace, automotive and other fields.
5 Excellent thermal conductivity: silicon carbide has excellent thermal conductivity, in the manufacture of radiators, electronic components and other aspects of a wide range of applications.
6. High bending strength: silicon carbide still maintains good bending strength at high temperature, which can be used to manufacture high-load and high-precision mechanical parts.
