Description

Customized durable 95% 96% 99% al2o3 alumina ceramic solid rod

What is alumina ceramics?

Alumina ceramics are industrial ceramics with high hardness that can only be processed by diamond grinding. It is made of bauxite and can be processed using injection molding, pressing, isostatic pressing, sliding casting.

The advantages of al2o3 alumina ceramic solid rod:

1.Corrosion resistance

High alumina ceramics are inorganic oxides with extremely stable molecular structure and no chemical corrosion, thus they can resist erosion of acid, alkali, salt solutions and organic solvents.

2.Thermonstability

Working temperature can be as high as 1400 degree.

3.Good self-lubricity

High alumina ceramic solid rod have the properties of self-lubricity, the roughness is only 1/6 that of steel pipes thus less flow resistance.In which it is abrasion, chemical, corrosive, corrosive and resistant to high temperatures and biological erosion, make them suitable for medical implants. The classification is based on their alumina content, which can vary from 70% to 99.9%. The higher the purity of alumina, the higher its wear and corrosion resistance. Welcome to contact us.

Surface roughness:

The surface processing of ceramic plates and tubes can achieve very high precision: the inner hole surface can reach 0.005mm, the outer hole surface can reach 0.001mm, and the mirror polishing can reach Ra0.1.
