Alumina 94% Machined Components
from Insaco, Inc.

Alumina (Al2O3) is one of the most widely specified, general-purpose technical ceramics. All aluminas are very hard and wear resistant, with high compressive strength even against extreme temperatures and corrosive environments. Aluminas are also excellent electrical insulators and are gas tight. [See More]
