Benefits of Sulfuric Acid Anodizing

One of the main reasons many industries and organizations choose type II anodizing is to avoid the use of chromium compounds (required for type I anodizing). Additionally, sulfuric acid anodizing offers several advantages:

  • Thicker oxide layer
  • Improved abrasion resistance and hardness
  • Increased corrosion resistance
  • Excellent electrical insulation

Custom Type II Anodizing Options

We adapt to the technical and aesthetic needs of your finished parts. Our color-anodized finishes are available in clear, black, gold, red, blue, and other colors. We also provide bright dip as a pre anodize process to produce a shiny surface.
