Alumina features high hardness and wear resistance, low erosion levels, high temperature and corrosion resistance and bio-inertness. Its high temperature stability and thermal conductivity make it particularly suitable for high temperature applications such as thermocouple protection in high temperature measurement.

• Excellent electrical insulation properties
• High compressive and dielectric strength
• High hardness and mechanical strength
• High thermal conductivity and thermal shock resistance
• Low density
• Resistant to strong acid and alkali attack at high temperatures
• Transparent to microwave radio frequencies
• Very specific thermal conductive and thermal expansion rates
• Wear and abrasion resistant

Alumina is available is multiple grades including 95%-99.9% high purity Alumina, high purity re-crystalized Alumina, and Zirconia toughened Alumina (ZTA). The following are the properties for 99.7% grade alumina.
