Alumina Ceramic Complex & Custom Parts
Alumina-Complex-Custom-Parts
Alumina ceramic is the most common technical material and relatively traditional ceramic. High-purity alumina has excellent performance in electrical insulation, high chemical resistance, and low thermal expansion. Alumina ceramics are used to make parts for CVD, ion implants, photolithography, and semiconductors. Edgetech processes Alumina Complex & Custom parts according to your drawings with a polishing roughness of Ra0.1-0.3um.

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. Edgetech Industries, Advanced Ceramics Division provides alumina products according to your specified instructions or does its best to meet requirements.
Advantages of Alumina Ceramic
-High hardness, Rockwell hardness is HRA80-90, second only to diamond, far exceeding the wear resistance of wear-resistant steel and stainless steel
-Excellent wear resistance, measured by professional research institutions, its wear resistance is equivalent to 266 times that of manganese steel and 171.5 times that of high-chromium cast iron. According to our customer maintenance survey over the past decade, under the same working conditions, it can extend the service life of the equipment by at least ten times
-Lightweight, its density is 3.9g/cm³, only half of that of steel, which can directly reduce the load on the equipment
Packing
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.
