Aluminum oxide has unique thermal conductivity qualities
and features low loss factors at high frequencies. It has high
compressive strength, high volume resistivity, low thermal
expansion and resists radiation.
Aluminum oxide insulating washers have a dielectric strength
of approximately 21.7 x 10
volts/mil for 0.030 inch material) and 16.9 x 10
1.57mm material (430 volts/mil for 0.062 inch material). The
thermal conductivity of aluminum oxide is 15.06W/(m°C) at 75°C.
