Ceramic Injection Molding Materials

Ceramic materials have the characteristics of high temperature resistance, corrosion resistance, high strength, high hardness and so on, and are widely used in various fields of industrial production

Metal Injection Molding Of Ceramics

95 alumina ceramics, porcelain refers to ceramic materials containing 95% alumina. 95 alumina ceramics have the characteristics of high temperature resistance, corrosion resistance, wear resistance, high mechanical strength, and high thermal conductivity.

95 alumina porcelain is one of the most commonly used ceramics in structural ceramics. Because alumina ceramics have excellent electrical properties at high frequencies, they have low dielectric loss, high volume resistivity, high strength, high hardness, small linear expansion coefficient, and particularly good wear resistance and heat resistance.

95% alumina porcelain, widely used in radio, electronic components, textile ceramics, ball mill lining, ball stone base sandblasting nozzle and argon arc welding torch nozzle, etc.

99 alumina ceramics, porcelain refers to ceramic materials containing 99% alumina widely used in environments with high-cleanliness, high-temperature, and high-wear-resistant environments. They are used to make high-temperature crucibles, refractory furnace tubes, and special wear-resistant materials, such as ceramic bearings, ceramic seals, and water valves.
