Machinable Glass Ceramics - Polycrystalline Composite, High/low-temperature Resistant, Acid & Alkali Resistant, Excellent Machine-ability

We are instrumental in providing excellent quality Machinable Glass Ceramics which is a polycrystalline composite made of fluorophlogopite and glass. It possesses good machine-ability and can be lathed, milled, planed, ground, bored, incised and threaded. It also has the advantages of insulation, pore-free, high/low-temperature resistant, acid and alkali resistant and thermal impact resistant.
