Advantages
Alumina ceramics are the most versatile of the advanced technical
ceramics stronger than the traditional ceramics chemically inert -
excellent corrosion resistance
outstanding electrical insulators, even at very high temperatures
extremely hard - excellent abrasion resistance are almost unaltered
at 1000°C useable up to 1700°
All alumina bodies possess very good mechanical properties such as
hardness and compressive strength. They also hold up well under
harsh conditions such as acid corrosion, high wear areas, and
sliding abrasion. They also possess very good electrical insulation
properties and have very specific thermal conductive and thermal
expansion rates.
