99% alumina ceramic shell

99% alumina ceramic shell is a high-purity alumina ceramic material with many excellent properties and is widely used in many fields.

performance parameter
High purity: Alumina content reaches 99%.
High hardness: very high hardness, reaching Mohs hardness level 9, second only to diamond.
High melting point: Melting point up to 2075 ° C, much higher than most metals and alloys.
High mechanical strength: It has high mechanical strength, although the mechanical strength decreases with temperature.
Excellent electrical insulation properties: with high resistivity, suitable for the manufacture of high-frequency, microwave and other electronic devices.
Good chemical stability: good corrosion resistance to most acids, alkalis, salts and other chemicals.
High temperature resistance: The maximum operating temperature can reach 1800 ° C.
Low density: The density is 3.9g/cm ³, much lower than that of metal materials.
Wear resistance: It has high wear resistance and is suitable for high-precision machining fields such as high-speed cutting and grinding.

Application field
Electronic and electrical appliances: used for IC packaging, substrates, spark plugs, vacuum switch housings, magnetron stem, etc.
Medical equipment: because of its non-toxic, tasteless, non-irritating, suitable for medical apparatus and biological materials.
Chemical equipment: used in the manufacture of circulating pumps, reciprocating pumps and resonator support products, is a good corrosion medium.
Aerospace: Due to its low density and high hardness, it has broad application prospects in the aviation and aerospace fields.
High temperature environment: used to manufacture high temperature structural parts such as crucibles, furnace tubes, and furnaces.
Machinery manufacturing: used for cutting tools, molds, watch bearings, grinding wheels, grinding balls, etc.

99% alumina ceramic shells play an important role in several high-tech fields due to their excellent physical and chemical properties.
