Shapal-M Machinable Ceramic Material

Shapal-M™ 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.

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.

Shapal-M soft is a new type of machinable ceramic with high mechanical strength and thermal conductivity. It is made on the basis of the first translucent aluminium nitride ceramic developed by Tokuyama Soda Co.Ltd. Based on it's new and unique characteristics, Shapal-M soft has a broad range of uses as a structural material and for many other applications.
