Black anodizing is not only cosmetic. The porous oxide layer raises infrared emissivity, which helps slightly in natural convection. The practical reason most customers choose it is colour matching with black chassis and front panels.
Coating thickness and shade
We typically run 10-15 µm. Deep black requires stable pre-treatment and rack positioning. For repeat orders we keep a colour reference coupon so batches do not drift.
Cleaning between fins
Dense fin parts trap solution. We rinse and dry thoroughly after sealing to avoid white stains in humid or salt-spray environments.
