Black Anodizing

Black anodizing is an electrochemical process that converts the surface of aluminum into a highly durable, corrosion-resistant aluminum oxide layer.

Anodizing significantly upgrades aluminum's wear and corrosion resistance, and a black anodized finish provides the added performance benefits of light absorption and highly efficient heat dissipation.

Depending on application, coating thickness, and post-anodizing sealing, our anodized finishes deliver an operational lifespan of 10 to 20 years. Vios has offered superior black anodized parts for clients from aerospace, automotive, and consumer electronics industries etc.
