Alumina ceramic rack : 1. Alumina ceramic has high hardness; 2. Alumina ceramic has very good wear resistance. 3. Alumina ceramics are light in weight. 
Advantages of alumina ceramics: alumina ceramics can produce more low-cost and higher-quality products for customers, because alumina ceramics are second only to diamond in strength, and because their wear resistance far exceeds that of alloy steel, in the same Under the same conditions, the service life is also more than ten times. In addition, the net weight of alumina ceramics is only half that of steel, which greatly reduces the load and loss of machinery and equipment. And the production cost of alumina ceramic raw materials is relatively low, which is an important new type of ceramic at present. As far as products are concerned, alumina ceramics have excellent dielectric strength, low high-frequency loss but good high-frequency dielectric strength, and secondly, alumina ceramic raw materials have temperature resistance, small linear expansion coefficient, and shock resistance. High toughness and good thermal conductivity. In addition, alumina ceramics have the characteristics of chemical corrosion resistance and molten metal resistance. It is not known that alumina ceramics are flame-retardant and stainless steel is strong and not easy to be destroyed. There are other materials and metal composite materials that cannot be compared. good features. Generally speaking, as people's understanding of this material continues to deepen, its application becomes wider and wider, and its price naturally becomes lower and lower. Due to its excellent electrical performance at high frequencies, it has low dielectric loss, high volume resistivity, high strength, high hardness, small linear expansion coefficient, and good wear resistance and heat resistance. It is more economical and practical to use 95% alumina ceramics in general occasions. 99% to 99.9% alumina porcelain is only used for occasions with particularly high performance requirements.
Alumina ceramics have the advantages of low thermal expansion, high thermal conductivity, high mechanical strength and good wear resistance. The use of alumina ceramics is to resist the erosion of gold and slag, and can also be used as special refractory materials, wear-resistant parts and tool materials in the machinery industry, and insulators in the electronics industry and other industries.
