General Information

Highest temperature ceramic

Absolute chemical resistance

No uptake of humidity

Non-porous

Not deformable

Great hardness

Outstanding insulating material at high voltages, a high frequency range at high temperatures

Achievable manufacturing tolerances up to 0.013 mm

Achievable surface roughness >0.5 µm to 0.013 µm (polished)

Processing can be done with usual metal processing tools for metal (metal cutting), thus purchase of expensive diamond tools is not necessary.
