Product Description
Alumina ceramic is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance but relatively low strength and fracture toughness.
Alumina Ceramics are generally white but may also be pink (88% alumina), or brown (96% Alumina). The colour is derived from either the sintering additives or impurities in the raw materials.
UNIPRETEC produces a range of high purity alumina ceramics in the range of 92% 99% purity.
92% Al2O3
Has very good electrical and mechanical properties and is metallized easily. The black body is used primarily for lids and when metallized and plated with gold has a very distinct appearance.
94% Al2O3
Possess very good electric and mechanical properties and is very easily metallized with the MoMn process.
96% Al2O3
This is our standard body and it has been formulized to meet with good success with just about anyone's MoMn process. This body still possesses the same good mechanical and electric properties as the previous two alumina bodies.
99% Al2O3
This body is used extensively in the medical industry. Its finer grain allows it to be polished to achieve fine micron finishes making it the material of choice for pump manufacturers and it is used for wire/thread guides as well as for mechanical seals. Though it can be metallized it normally does not lend itself to that process due to its lack of glassy phase.
