Glass ceramic materials may look and feel like glass, but they are highly durable and well suited to handle extreme temperatures and temperature changes. Glass ceramic materials can be configured to meet demanding requirements as they offer many advantageous features including, high impact resistance, high strength and toughness, good thermal shock resistance, extremely low or sometimes even negative coefficient of thermal expansion, isolation capabilities, and a range of optical properties from transparent to opaque. CGQPI can CNC mill, drill, cut, lap, and polish Glass Ceramics in many sizes, shapes, and surface finishes.
