What’s the thickness of different anodizing coatings?

Anodizing is a surface treatment mainly used on aluminum CNC parts to improve corrosion resistance and wear performance. One key detail engineers often ask about is coating thickness, especially when tolerances matter.

Here’s typical standard:

✅ Natural color anodizing: around 0.008 mm

✅ Other colors anodizing: around 0.015 mm

✅ Hard coat anodizing: around 0.025–0.030 mm

✅ Conductive anodizing: around 0.003 mm

Actual thickness may vary slightly due to process and measurement method.

💡 If your part has tight tolerances or critical fit surfaces, let us know your requirements before production so we can help you choose the right anodizing option. 💙
