Aluminum anodizing
Type II and Type III anodizing in clear and black — a hard, corrosion-resistant, electrically insulating oxide layer that also looks premium on aluminum.
What anodizing does
Aluminum anodizing converts the surface to aluminum oxide — much harder than the base metal, dyeable and sealable. Type II (decorative, 5–25 µm) is standard; Type III / hard anodize (≥ 25 µm) adds wear resistance. Black anodized aluminum is the common choice for enclosures and heatsinks.
Typical specs
- Type II: 5–25 µm
- Type III: ≥ 25 µm
- Color: clear / black / RAL
- Salt spray: per spec

Anodizing notes
- Anodize after machining; mask critical features if needed.
- Silicon-rich 4xxx welds won't anodize evenly — plan finish.
