Alumina Ceramics have excellent electrical, wear resistant, and high temperature properties. Our Alumina ceramic products also exhibit excellent mechanical strength, and can operate at safe operating temperatures up to 1550 C. Typical applications of alumina ceramics include, but are not limited to, electrical heating elements, fuses, igniters, resistors, stand offs, ceramic thermocouple cores, load banks, ovens, furnaces, connectors, ceramic knife sharpeners, ceramic substrates, heat sinks, sensors and ceramic spacers
