Below is a list of Alumina Ceramic manufacturers from Hasbrouck Heights, New Jersey. Alumina ceramic, or aluminum oxide, is an extremely durable and cost effective option used in many industrial and commercial applications. The strong ionic interatomic bonding of alumina provides it with many attributes desirable in ceramic production. Extreme hardness, resistance to weathering, high density, wear resistance, thermal conductivity, high stiffness, chemical resistance and compressive strength all put this ceramic in high demand even in comparison with other ceramics. Aluminum oxides offer up to twenty times the thermal conductivity of most other oxides.
