Aluminum Anodizing is an electrochemical process that creates a thin aluminum oxide film on the surface of aluminum substrates. The resulting anodized film is electrically non-conductive, protects the aluminum against corrosion and is resistant to wear.
Is anodizing thermally conductive?
Thermal conductivity of aluminum anodic oxide layer was measured. Measured thermal conductivities fell in the range of 0.53–1.62 W m−1 K−1. Both chemical composition and porosity were affected the thermal conductivity.
Is anodizing an insulator?
Heat Resistance
The aluminium oxide coating produced by anodising is a good insulator where good heat dissipation is required.
