Alumina occurs abundantly in nature, most often as impure hydroxides which are the essential constituents of bauxite ores.
Most raw bauxite is refined by the Bayer process and alumina with various degrees of purity is made.
The superior characteristics of alumina are:
- thermal resistivity
- electrical insulation
- hardness
- chemical stability
- wear resistance
- sliding properties

Reproducibility and economical cost guarantee an extremely wide range of applications.

The Alox® family includes a series of specific ceramic powders for different application fields:
Alox G – Alumina 96% (brown) for circulating pump shafts
Alox C – Alumina 99% (white) for medium/high pressure pistons
Alox CP – Alumina 99% (white) ideal for monocommand disks for taps and fittings
Alox R – Alumina 98.5% (pink) ideal for thermal shock problems

Ceramic components manufactured through Alox sintering present a high density together with excellent surfaces obtainable thanks to a grinding and lapping process based on the customer’s requests.
