More info

Sapphire Components are designed for instruments and equipment that must endure harsh environments. With a Mohs hardness of 9, excellent abrasion resistance, superior chemical stability, and a maximum temperature tolerance of 2060°C, sapphire significantly enhances the durability and lifespan of precision parts. Typical applications include water and electric meter bearings, chemical pump valves, and textile machine guides. These components often have complex shapes and precise sealing requirements. Heeger Materials can custom-manufacture sapphire components according to client drawings, using advanced cutting, grinding, polishing, and inspection equipment to ensure each product meets stringent quality standards.
