Alumina Ceramics
AL₂O₃

Alumina is a well-known and commonly used precision ceramic material. It has the same sintered crystal as sapphire and ruby. For decades, it has been used in electrical components because of its high electrical insulation. Because of its high strength, high corrosion resistance and high wear resistance, it is widely used in mechanical parts.

Alumina is an excellent high temperature ceramic material due to its high temperature stability. It is the most commonly used type of advanced ceramic and is available in purities ranging from 95 – 99.5%. China Ceramics Parts has access to many different types of Alumina including: injection molded, die pressed, isosostatically pressed, slip cast, and extruded.

Feature

High Temperature Ability – Alumina can be used in both oxidizing and reducing atmospheres up to 1650°C (2900°F) and in vacuum environments up to
2000°C (3600°F). Abrasion Resistant – Alumina is a very hard ceramic and is excellent at resisting abrasion. It is ideal for wear-resistant inserts or products.
Electrical Insulator – Alumina is commonly used as a high temperature electrical insulator, particularly the higher purity grades which offer better resistivity.
Chemical Resistance – Alumina offers good resistance to strong acids and alkalis at elevated temperatures and is ideal for applications where resistance to corrosive substances is required.
