Customized high temperature wear resistant 99 alumina ceramic seal ring mechanical structure parts

Alumina ceramics are precision ceramic materials that are widely used in various industries. Alumina ceramics is a ceramic material with a-Al2O3 as the main crystal phase. It is widely used in various fields such as dry ceramics, electronics, textiles, chemicals, construction and aerospace.Alumina ceramics have high mechanical strength, high insulation resistance, high hardness, wear resistance, corrosion resistance, high temperature resistance, low thermal expansion, andA series of excellent properties such as high conductivity, high mechanical strength and good wear resistance. It is resistant to the erosion of gold and slag, and can also be usedIt is used as special refractory materials, wear-resistant parts and tool materials in the machinery industry, and used as insulators in the electronics industry and other industries.
