We can provide a variety of high-performance engineering ceramics.

Silicon Nitride Ceramics (Si3N4)

Silicon nitride exceeds other ceramics in thermal shock resistance. Its strength does not deteriorate at elevated temperatures, hence it is most appropriate for engine and gas turbine parts, including turbo charger rotors, diesel engine glow plugs and hot plugs.

Alumina Ceramics (Al2O3)

Alumina is the most widely used type of ceramic. Its high dielectric properties are beneficial in electrical products, Alumina offers corrosion and wear resistance and high strength. It is widely used for industrial machine parts.

Silicon Carbide Ceramic (SiC)

Silicon carbide retains its strength at elevated temperatures as high as 1400℃. It has the highest corrosion resistance of all fine ceramic materials. Applications include mechanical seals and pump parts.

Zirconia Ceramics (ZrO2)

Zirconia ceramic has the highest strength and toughness at room temperature of all engineering ceramics. Before zirconia, ceramics were considered impractical for scissor or knife applications. With its excellent surface smoothness, zirconia is also used for pump parts.

Aluminum Nitride Ceramics(AIN)

Aluminum nitride ceramics are usually gray or off-white. It has a low thermal expansion coefficient, excellent insulation performance, heat resistance, and a thermal conductivity of more than 180W/(m.k). It is an ideal package heat dissipation material for large integrated circuits.

Machinable Glass Ceramic

Machinable glass ceramics are fluorophlogopite mica glass ceramics with synthetic mica as the main crystal phase. The main components are fluorophlogopite and glass with silica as the main component. Contains 55% fluorophlogopite and 45% borosilicate glass matrix.

Microporous Ceramic Plate

Microporous ceramics refer to ceramic bodies containing a large number of open or closed tiny pores. The material is mainly alumina or carbonized. The surface is firm, the pores are uniform, the porosity is 35-40%, and the pore size ranges from 1 to 100 microns.

Boron Nitride(h-BN)

Boron nitride material has the characteristics of resistance to high temperature and heat cycle. It will not react with many metals, ceramic rare earths and other materials, nor will it contaminate the product. Will not break in hot and cold environments.

Other Ceramics

Our company can process a variety of ceramic materials and cemented carbide. We are currently processing experimental splines for many research institutes and schools. You can provide materials and we can process them according to drawings.

We can provide products according to your drawings or samples and performance requirements.
