99.97% Alumina
INCERCO'S 99.97% Alumina ceramic is the representative material of today's technical
ceramics.  Similar to sapphire, INCERCO 99.97% Alumina ceramic is comprised of corundum
crystals.  INCERCO 99.97% Alumina is manufactured with our SFG (Small, Fine Grain)
technology and thus it has outstanding properties as an industrial material.

With a hardness next to diamond, boron carbide and silicon carbide, INCERCO's 99.97%
Alumina ceramic with SFG technology  has superior wear resistance.

INCERCO's 99.97% Alumina ceramic has excellent high insulation resistance at elevated
temperatures, high dielectric strength at high voltage, and low dielectric loss tangent at high
frequencies.

INCERCO's 99.97% Alumina ceramic is inert to oxidation, is not corroded by chemical agents
and is not subject to radiation damage.
