Alumina Complex & Custom Parts
Boron Carbide Parts China, Advanced Ceramics Division supplies high-quality and competitive price advanced Alumina Complex & Custom Parts.
Alumina Complex & Custom Parts
Alumina ceramic is the most common technical material and relatively traditional ceramic. High purity alumina has excellent performances in electrical insulation, high chemical resistance, and low thermal expansion. Alumina ceramics are used to make parts for CVD, ion implants, photolithography, and semiconductor.

The above chart just demonstrates the typical properties of common alumina ceramic we use to produce our alumina parts. Please notice that the properties of customized alumina parts vary due to different processing. Boron Carbide Parts China, Advanced Ceramics Division provides alumina products according to your specified instruction or does its best to meet requirements.
Packing of Alumina Parts
As a ceramic material, Alumina Parts are quite fragile in a lot of cases. Our Alumina Ceramics are carefully handled to minimize damage during storage and transportation. Suitable outer boxes and inner cushioning materials are used, and vacuum packing is also engaged for some of the parts.
