PRECISION INVESTMENT CASTINGS

Mullite (calcined kyanite) is widely used in the manufacture of investment casting molds because mullite is stable at high temperatures, has a very low coefficient of thermal expansion, and is friable to an extent that allows the cast piece to be easily removed with high pressure water or sand blasting. In this regard, Kyanite Mining Corporation’s products are instrumental in the manufacture of numerous consumer and industrial products, including turbine blades for jet engines, golf club heads, false teeth, and automobile engines blocks.
