Will anodizing affect the heat dissipation effect of the exruded aluminum heat sink?

The Aluminum Heat Sink after anodizing will be more beautiful, increase surface hardness, and extend service life. Whether to anodize or not depends on the product's requirements. The external parts need to be anodized, while the internal parts can be oxidized or not. Whether to oxidize or not does not have a significant difference in the heat dissipation effect of the aluminum heat sinks.
