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 Alumina Substrates
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.
