alumina ceramic parts support customization 95% AL2O3 high accuracy various electronic accessories

product name:Alumina ceramic accessories

Alumina ceramics have excellent high temperature properties and high mechanical strength, and are widely used in many industrial fields such as metallurgy, machinery, chemical industry, electronics, aviation and national defense. Its main purposes are as follows :
1. Alumina ceramic has high temperature resistance, corrosion resistance, high strength and other properties, so it is used as a sliding nozzle to smelt rare and precious metals, special alloys, high-purity metals, glass drawing crucibles and vessels. Various high-temperature furnaces, such as refractory materials, ceramics, iron-making blast furnace lining ( walls and tubes ) ; physicochemical vessels, spark plugs, heat-resistant and anti-oxidation coatings. The low silicon sintered corundum brick with SiO2 less than 0.5 % is the special lining for carbon black, boron chemical industry, chemical fertilizer, ammonia synthesis reaction furnace and gasification furnace.
2. At the same time, the alumina ceramic has the characteristics of high hardness, good wear resistance and high strength. It is used as a variety of reaction vessels and pipes, chemical pump components in the chemical system. For mechanical parts, a variety of molds, such as wire drawing die, extrusion pencil die mouth, etc. ; for cutting tools, abrasives, bulletproof materials, human joints, sealed grinding rings, etc. ;
3, and there is high temperature insulation, so it is used as a thermocouple sleeve tube and protection tube, the insulation used in the atomic reactor is still excellent, coupled with the loss is not large, the dielectric constant is not large, in the electronics industry is widely used in solid integrated electric furnace substrate tube seat, shell, porcelain frame, thin window, missile radar antenna protective cover, etc. ;
