Description

Machinable Glass Ceramic has a continuous use temperature of 800ºC and a peak temperature of 1000ºC. Its coefficient of thermal expansion readily matches most metals and sealing glasses.It processes good machinability and can be lathed, milled, planed, ground, bored, incised and threaded. It also has the advantages of insulation, pore-free, high/low-temperature resistant, acid and alkali resistant and thermal impact resistant. In terms of machinability, it can take the place of aluminum oxide and boron nitride ceramics that are difficult to machine.

This material data has been provided by Innovacera.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
