Ceramic Core Alumina (Al2O3) Heater

High compression strength, hardness and wear resistance, Alumina heaters facilitate high heat resistance and high thermal conductivity applications. Ideal solution for small to mid-size heaters where uniform surface temperature is required, Alumina provides the highest insulation standoff per unit thickness.

  • High-temperature heater up to 1000°C
  • High compression strength.
  • Very hard and wear resistant.
  • Superior material flexibility and bend strength.
  • Excellent size and shape capability.
  • Precise, repeatable pattern and distributed wattage.

About Ceramic Core Alumina

Featuring precise, controlled heat for high-temperature applications up to 1000°C, Thick Film Alumina heaters offer low mass, low leakage current, and excellent dielectric properties. Excellent smaller heaters where high heat resistance and high thermal conductivity are required.

  • For high temperature applications between 350 °C and 1000 °C.
  • High temperature uniformity.
  • Excellent dielectric properties.
  • Low mass: fast temperature ramp up and cool down.
  • Low leakage current.
  • No outgassing with inorganic systems.
  • Resistant to moisture and many chemicals.

Engineering services and consultation are available on every custom heating element order. Contact a specialist today for details.

Configuration Options

  • High temperature glass and conventional UV-cure resin-bases solder masks or encapsulants.
  • Design single- or double-sided circuits, with one or two layers per side.
