Alumina ceramic special-shaped parts
Alumina is a high hardness industrial ceramic that can only be processed by diamond grinding, by injection molding, pressing, isostatic pressing, sliding casting, etc. The higher the purity of alumina, the more abrasive and corrosive it is.

Alumina is a high hardness industrial ceramic that can only be processed by diamond grinding, by injection molding, pressing, isostatic pressing, sliding casting, etc. The higher the purity of alumina, the more abrasive and corrosive it is. Alumina ceramics are made from a white granular material that resembles salt or a very fine thick powder. The three general types of alumina are hydrated, calcined and chimeric. It has good insulation and high temperature resistance, very high mechanical strength, very good conductivity, and very light weight. The density of alumina ceramics is very small, its density is 3.5 grams per cubic centimeter, and its density is only half of that of steel. Usually, in the case of the same volume, the quality of alumina ceramics is only half of that of steel. Alumina ceramic protective cover has very good wear resistance. The wear resistance of alumina ceramic fittings is more than 200 times that of manganese steel. Alumina ceramics have excellent mechanical strength, high temperature resistance, wear resistance, wear resistance, good insulation performance and durability. Long life, energy saving, environmental protection, safety, control points and other advantages. Therefore, the characteristics of alumina ceramics have been widely used in various industries such as military ceramics and petrochemical ceramics, including but not limited to coal transportation and material delivery in steel, machinery, port logistics and other companies. For some damaged industrial equipment such as system software, milling system software, ash conveying, dust removal equipment, etc., different types of products can be selected according to different requirements. Alumina ceramics have excellent dielectric strength, high-frequency loss is relatively small but high-frequency dielectric strength is good, followed by alumina ceramic raw materials with temperature resistance, small linear expansion coefficient, high impact toughness and heat conduction In addition, alumina ceramics have the characteristics of chemical corrosion resistance and molten metal resistance, but it is not known that alumina ceramics are flame-retardant, and stainless steel is strong and not easy to be destroyed, which have good characteristics that other materials and metal composite materials cannot compare.
