Photoveel Machinable Ceramic Material

These fine-grained machinable ceramics are not only machinable with conventional tooling, but also nearly as strong as alumina and other hard ceramics. Machinability plus high strength fine grain structure makes these materials an ideal fit for applications that require precision machined features.
