Description

Pyrophyllite (Aluminium silicate) is a machinable mineral which, after heat treatment, assumes many of the properties of fired ceramics. It is ideal for prototypes, experimental and pilot scale productions where high accuracy is required on small parts. When this material is heat treated it hardens and its properties change; we therefore supply Pyrophyllite in three grades:

The natural material. Extremely easy to fabricate, but of rather low strength.
Heat treated to 800 - 1000 °C. This grade is characterized by its low thermal conductivity and coefficient of thermal expansion, resulting in very good thermal shock resistance. This version of the heat-treated material can be machined to final size with tungsten carbide tools.
Heat treated to 1250 - 1300 °C. This grade is characterized by its excellent electrical properties, high strength and hardness. This version of the heat-treated material can only be machined with diamond tooling.
