Acid Etch

Give It a Matte Finish!

Process Quality

Acid etch is a chemical etch step in the aluminum anodizing process which offers a better finish consistency and is environmentally friendly. It provides a cosmetic matte finish similar to bead/sand blasting, reducing time and costs in part finishing.

There are many benefits to acid etch anodizing:

  • Reduces, or in some cases eliminates, die lines and surface defects
  • Provides a superior matte finish for cosmetic consistency
  • Provides better color consistency
  • Environmentally friendly alternative to caustic etch
  • Meets AAMA 611 specification
