company specializes in the production of alumina industrial ceramic accessories, customized according to size, with an alumina content of 99%. It includes mechanical components, electronic insulation accessories, and ceramic products
Advantages of alumina ceramics:
1. Aluminum oxide ceramics have excellent insulation properties, with relatively low high-frequency losses but good high-frequency insulation properties;
2. Aluminum oxide ceramics have the characteristics of heat resistance, low coefficient of thermal expansion, high mechanical strength, and good thermal conductivity;
3. Aluminum oxide ceramics have characteristics such as chemical corrosion resistance and molten metal properties.
4. Aluminum oxide ceramics have excellent properties that are non combustible, rust resistant, sturdy, and not easily damaged, which are incomparable to other organic and metal materials;
5. Aluminum oxide ceramics have wear resistance, but their hardness is the same as that of corundum, and they can achieve Mohs hardness. The wear resistance is comparable to that of superhard alloys.
