Key Anodizing Types to Consider

When requesting a quote, be prepared to specify which type of anodizing your aluminum parts require:

1. Type II (Sulfuric Acid Anodizing): The most common method; excellent for general corrosion resistance and allows for vibrant color dyeing.
2. Type III (Hardcoat / Hard Anodizing): Creates a much thicker, extremely dense and wear-resistant surface layer, ideal for mechanical or industrial parts.
3. Type I (Chromic Acid Anodizing): A thinner coating used primarily for aerospace components where fatigue resistance and minimal dimensional change are critical.

To help narrow down the best shop or get a more tailored recommendation, let me know:

• What geographic location or state are you looking in?
• What type of anodizing (Sulfuric, Hardcoat, or Chromic) or industry standard (Mil-Spec, RoHS, etc.) do your parts require?
• What is your estimated production volume (prototypes vs. high-volume production)?
