Aluminum Nitride (AlN) Heater Plates
High thermal conductivity makes AlN an excellent choice where fast response or high levels of uniform temperatures are required. A clean, non-contaminating heat source, AlN’s high thermal conductivity prevents cracking.
- High-temperature heater up to 1000°C
- Excellent thermal conductivity and uniformity.
- Hard, dense, non-porous, high purity substrate.
- Superior moisture and chemical resistance.
- Excellent size and shape capability.
- Precise, repeatable pattern and distributed wattage.
Precision engineered to fit tight spaces and tolerances, Thick Film AlN heaters are found in the most critical medical, aerospace and commercial applications. Fast ramp-up time, low leakage and excellent dielectric properties make this our highest-performing thick film alternative.
- For high temperature applications up to 1000 °C
- Power densities to 155 W/cm2 (1000 W/in2)
- Superior thermal conductivity (220 W/mK)
- Excellent dielectric properties
- Low coefficient of thermal expansion
- Low mass: fast temperature ramp up and cool down
- Low leakage current
- No out gassing with inorganic systems
