Product Description

99% Alumina Ceramic customized spare parts factory

Reputation depends on quality, quality comes from Hard!

Alumina Ceramic:

The main components of ruby and sapphire are alumina, which have different colors due to other impurities. Ruby contains red chrome oxide and red sapphire contains iron oxide and titanium dioxide.Alumina is the reason why metal aluminum is not easily corroded in the air. Pure metal aluminum reacts easily with oxygen in the air, creating a thin layer of aluminum oxide film that covers the aluminum surface exposed to air. This layer of aluminum oxide film prevents aluminum from being oxidized. The thickness and properties of this oxide film can be enhanced by a process known as anodizing (anode anti-corrosion).Aluminum is a good conductor of electricity and heat, while alumina is an electrical and thermal insulator. The crystal form of alumina is high in hardness and suitable for use as an abrasive material and cutting tool.


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

  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 .
