Alumina ceramic air knife

Alumina Ceramic Air Knife and Tin-Coated Ceramic Air Knife Product Introduction:

Alumina Ceramic Air Knife

1. Material Characteristics:

• High Hardness: Rockwell hardness reaches HRA80-90, second only to diamond, and its wear resistance is equivalent to 266 times that of manganese steel.

• High Temperature Resistance: Can work stably in high-temperature environments above 1000℃.

• Corrosion Resistance: Does not react with many chemical substances and is suitable for strong acid and strong alkali environments.

• Lightweight: Density is approximately 3.6 g/cm³, only half that of steel.

• Insulation Performance: Volume resistivity > 10¹² Ω·cm, dielectric strength 15 kV/mm

Industrial Applications

• Wafer trays in chip manufacturing.
