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.
