Edgetech offers a wide range of custom alumina fasteners, including ceramic screws, threaded rods/bolts, and matching washers and ceramic nuts.

Alumina ceramics are widely used as general ceramics. It is used for large equipment parts and precision machinery parts by taking advantage of its wear resistance, high hardness, dimensional stability, etc. It can be used continuously at a temperature of 1500 degrees. In addition, it can be bonded to metals through heat treatment, has excellent corrosion resistance, and does not release gas at high temperatures, so it is widely used in semiconductor equipment.
