Alumina ceramics are industrial ceramics with high hardness and can only be processed by diamond grinding. It is made from bauxite and can be processed using methods such as injection molding, pressing, isostatic pressing, slip casting, etc. Products made from alumina, among others, its resistance to wear, chemical, corrosion, corrosion and high temperature and bioerosion, making them suitable for use in medical implants. Alumina ceramics are classified based on their alumina content, which can vary from 70% to 99.9%. The higher the purity of alumina, the higher its wear and corrosion resistance.
With the application of alumina ceramics in more and more places, many people will consider using alumina ceramics when purchasing mechanical equipment parts. Parts in different parts require different materials because of their different functions. The environment in which some parts operate is very harsh. They may face high destructive and lethal threats such as high temperature, strong acid and alkali, high voltage, and strong current. Therefore, only parts processed with high-performance materials can be used in these environments. normal operation. At this time, the appearance of alumina ceramics has made people's eyes shine. It has the properties of high temperature resistance, wear resistance, chemical resistance and high density.

Some of the key benefits of alumina include: High temperature capability – alumina can be used in oxidizing and reducing atmospheres up to 1650°C (2900°F) and in vacuum environments up to 2000°C (3600°F).

Wear Resistant - Alumina is a very hard ceramic with excellent wear resistance. It is ideal for wear resistant inserts or products.

Electrical Insulator – Alumina is commonly used as a high temperature electrical insulator, especially higher purity grades that offer better resistivity.

Chemical Resistance - Alumina has good resistance to strong acids and bases at elevated temperatures and is ideal for applications requiring resistance to corrosive substances.
