Alumina Ceramic Parts

Alumina Ceramic Parts

Alumina Ceramic Parts is the most cost effective and widely used material in the family of engineering ceramics, the raw materials from which this high performance technical grade ceramic is made are readily available and reasonably priced, resulting in good value for the cost in fabricated alumina shapes.

It features high hardness and wear resistance, low erosion levels, high temperature resistance, corrosion resistance, and bioinertness. Additionally, Its high dielectric properties are beneficial in electronic products.

Applications include semiconductor processing equipment parts, faucet disc valves, seals, electronic substrates and industrial machine components.
