Shapal - Machinable Ceramic
Machinable CeramicShapal™ is a new type of machinable ceramic and combines a high thermal conductivity with a high mechanical strength with bending strengths of 30 kg/m. Shapal-M soft, in particular, has an excellent sealing ability to vacuum. It also has good heat resistance and an extremely low coefficient of thermal expansion.
Shapal-M maintains a low dielectric loss and also has an ultra high purity level.
Typical applications: Electronic components, especially where electrical insulation and heat dissipation are required. Also components where low dielectric constant and dissipation factor are required; fixturing parts where a low coefficient of thermal expansion is required. "Excellent machinability, high thermal conductivity and high mechanical strength applicable to structural and a broad range of other uses"
Ceramic materials are distinguished from metals and organic materials for their unique characteristics, but their use is limited because of difficulty in machining as they are generally hard and brittle.
Recently some kinds of machinable ceramics have been developed for better machinability and they have attracted special interests. Although they have high machinability, they are not applicable in the engineering purposes due to the low bending strength as low as 10Kg/mm².
