Alumina Ceramics:

Advantages of alumina ceramics:
1, good wear resistance
Ceramic composite pipe is made of corundum ceramic (a-AL2O3), Mohs hardness up to 9.0 is equivalent to HRC90 or above. Therefore, it has high wear resistance for grinding media conveyed by metallurgy, electric power, mining, coal and other industries. Sex. It has been confirmed by industrial operation that its wear life is ten times or even several times that of hardened steel.


2, the running resistance is small
Because the inner surface of SHS ceramic composite pipe is smooth and never rusted, it does not have the convex spiral line on the inner surface of the seamless steel pipe. The inner surface roughness and the water resistance resistance test are tested by the relevant testing unit, and the inner surface smoothness is excellent. In any metal pipe, the coefficient of clearing resistance is 0.0193, which is slightly lower than that of the seamless pipe. Therefore, the pipe has the characteristics of small running resistance and can reduce the running cost.

3, corrosion resistance, anti-fouling
Because the steel ceramic layer is (a-AL2O3), it is a neutral trait. Therefore, it has acid and alkali resistance and seawater corrosion resistance, and at the same time has anti-scaling and other characteristics.

4, temperature resistance and heat resistance
Because the corundum ceramic (a-AL2O3) is a single stable crystalline structure, the composite tube can operate normally for a long time in the temperature range of -50--700 ° C. The linear expansion coefficient of the material is 6-8*10-6/0C. About 1/2 of the steel pipe. The material has good thermal stability.
alumina disk

properties:

High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.

SHENZHEN HARD PRECISION CERAMIC CO.,LTD

  Shenzhen Hard precision ceramics Co., LTD. has been committed to design, development and manufacture of industrial ceramic products since 2007. Compared with metal, advanced ceramic has the following excellent performance: high hardness, high strength, high temperature (fire), and can wear resistance, corrosion resistance, acid and alkali resistance, oxidation resistance, insulation, non-magnetic and good chemical stability . So it is often used in the environment where the metal material cannot endure. With its promising application , advanced ceramics are widely used in aerospace, aviation, military industry, nuclear power, machinery, textile, chemical, electronics, food, medical and other industries. Our advanced ceramic products made by zirconia (ZrO2), alumina (Al2O3), silicon nitride (Si3N4), etc. Our products can divide into two parts: one part is ceramic ball, rods, tubes, ceramic materials such as plate, block, strip and so on, and the other part is the precision ceramic parts which are for industrial use and civilian products. Our company has advanced one-stop equipment and technology of ceramic forming, sintering and processing. Hope we can establish excellent cooperation with customers from at home and abroad for a wide range .
