Dongguan Ming Rui Ceramic Technology Co., Ltd
Alumina ceramics due to its different alumina content is divided into a variety of such as 75 alumina, 85 alumina, 95 alumina.99 alumina is a kind of high purity, its mechanical properties will be stronger.
Alumina ceramic materials are often used in chemical and physical grinding environments, especially high purity alumina is a very good material for producing wear-resistant components.
These components include shafts, pistons, bearings and mating end seals, which are used primarily in chemical and physical conditions and are good corrosive media.These components can be used to manufacture circulating pumps, reciprocating pumps and resonator supported products.
Ceramic injection molding and precision grinding can usually be used to produce a variety of surface finish and flatness requirements of complex components.These components are frequently used in water management, medical, automotive, telecommunications and home appliance applications.
Properties of 99% alumina:
Alumina has a high melting point, high hardness and high mechanical strength, although the mechanical strength temperature drops to over 1000°C.
Due to the relatively large thermal expansion coefficient increases, the thermal shock stability decreases.
Alumina is an electrical insulating material with high resistivity.It also has a good chemical stability of alumina, so good corrosion resistance.
Alumina is insoluble in water, only slightly soluble in strong acid and alkaline aqueous solutions.
Alumina is the most mature engineering ceramics, which provides excellent electrical insulation, high hardness and wear resistance but relatively low strength and fracture toughness.
