Structural Ceramics for Industrial, Electronics, and Energy

Structural ceramics are used in a wide array of applications for industrial, electronics, and energy sectors due to properties such as high temperature resistance, excellent electrical insulation, high dielectric strength, good mechanical strength and durability, chemical resistance, lightweight design, thermal management capabilities, and the potential for miniaturization and integration. These attributes contribute to improved system performance, reliability, longevity, and overall efficiency in various industries and applications.

Fralock offers a selection of ceramic materials that begins with powder and is precision-engineered and processed for optimal performance and durability to produce your custom component. We can fabricate features such anti tracking grooves and reliefs to accommodate thick film metallization and provide parts up to 31” in diameter and 3” thick, with green to fire Alumina tolerances +/- 1.0% and hard grind to tolerances within 0.00002” (0.000508mm).

Fralock’s Ceramic Materials include:

  • Alumina, zirconia, quartz, aluminum nitride, and silicon carbide ceramics.
  • Near net shape ceramic components made from alumina and aluminum nitride
