Alumina Purities ranging from 60% up to 99.8%

Alumina Purities ranging from 60% up to 99.8%

Aluminum Oxide, Al2O3
High Purity Alumina is the most cost effective and widely used material in the family of engineering ceramics. The raw materials from which this high performance pure grade ceramic is made are readily available and reasonably priced, resulting in good value for the cost in fabricated alumina Tubes, Rods, Insulators and machined shapes. With an excellent combination of properties handling thermal shock and mechanical shock, it is no surprise that fine grain technical grade alumina has a very wide range of applications.

Holding large stocks at all times we strive to give a excellent service and as well as our normal range of ceramics we are a stocking distributor for Haldenwanger Technical Ceramics with products such as Alsint, Pythagoras , Sillimantin
