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...
Boron nitride is offered in several grades each with unique materal properties. All however, are readily machinable; much like green (not sintered), alumina BN allows drilling, tapping, treads etc. without...
Macor is a relatively easy material to machine using ordinary carbide drills, end mills, taps, etc. and doesn’t require post machining firing. Macor-Machinable Glass Ceramic is also unique in that...
San Jose Delta maintains an extensive in-house inventory of certified Materion beryllia ceramic machining stock, including BW-1000, a higher strength and finer grain berylia,. While the grinding of 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...
San Jose Delta performs precision machining, grinding and polishing services on ceramics, Macor-Machinable Glass Ceramic by Corning, Beryllium Oxide, Quartz and other hard and ceramic like materials.
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...
