Thick Film Aluminum (Al)



About Thick Film Aluminum


Thick Film Aluminum's exceptional thermal conductivity and high power densities make it an excellent option for low-heat applications that require a high-degree of control. The aluminum substrate allows for three dimensional forms with the flatness of a Thick Film heater. Available with integrated sensors, thermostats and a variety of mounting and attachment options.

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

High thermal conductivity makes Aluminum an excellent substrate where fast, uniform heat transfer is required. Aluminum’s anodization acts as a natural insulator that offers outstanding reliability and efficiency. Recommended for low-heat and 3-dimensional installations.
