San Jose Delta Associates, Inc. Datasheets for Aluminum Oxide and Alumina Ceramics

Aluminum oxide and alumina ceramics have excellent wear characteristics, chemical resistance, compressive strength, high-temperature properties, and dielectric strength. They are used widely because of their versatility and low cost. Their main drawback is its relatively poor thermal-shock resistance due to higher coefficients of thermal expansion and lower thermal conductivity (compared to other pure ceramic materials).

Product Name Notes
Aluminum Nitride - AlN, is most often the material of choice due to its relatively excellent thermal conductivity and non-toxic nature. Because San Jose Delta has a segregated beryllium oxide...
San Jose Delta maintains an in-house inventory of most grades of alumina ceramics as BARS-RODS-TUBES and SHEETS. The availability of fired “grinding stock” ceramic makes the production of small quantity...
Sapphire is diamond ground using the same general processes as any dense alumina oxide material. While it tends to chip easier than alumina, simple grinding procedure and technic can accommodate...
While the same design features common to alumina ceramics; blind holes, threads etc. are easily produced in Zirconia the grinding time required is about fifty percent more. The post-grinding surface...
