99 alumina
Your current location is: Website home page " Ceramic material " alumina " 99 alumina

99 alumina ceramics Materials are often used in chemical and physical grinding environments, especially high purity alumina, which is a very good material for producing wear-resistant components. These components include shaft, piston, bearing and mating end seal. They are mainly used in chemical and physical conditions, and are excellent corrosion media. These components can be used to manufacture circulating pumps, reciprocating pumps, and vibrator supported products.

Fly by ceramic injection molding and precision grinding process can produce various kinds of complex components with surface finish and smoothness. At the same time, the manufacturing process of flying can also meet the requirements of small quantity and mass production. These components are frequently used in environmental engineering, medical food, automotive industry, telecommunications and household appliances. If you are interested in our 99% alumina component, we will very much welcome you to use high purity alumina. The high purity alumina we provide to you will once again show the extremely high hardness and abrasion resistance of alumina ceramics.

99% alumina properties  
Alumina has high melting point, high hardness and high mechanical strength, although the mechanical strength temperature decreases to more than 1000 degrees C. Because of the relatively large thermal expansion coefficient, the thermal shock stability is reduced.  
Alumina is an electrical insulating material with high electrical resistivity. It also has good chemical stability of alumina, so it has good corrosion resistance. Alumina is insoluble in water and only slightly soluble in strong acids and alkaline solutions.  

99% alumina application  
Alumina is the most mature engineering ceramics, it provides excellent electrical insulation properties, high hardness and wear resistance, but relatively low strength and fracture toughness.  
Different types of alumina alumina are usually white, but sometimes they are pink (88% alumina) or brown (96% alumina). Color comes from impurities in additives or raw materials.
