Type 3 Anodizing – Class 1 & 2

We meet tight tolerances for Type 3 anodizing using our unique control systems to achieve accurate coating thickness of aluminum anodized parts. Our services include dying options.

Benefits of Sealed Type 3 Anodizing

  • Closes Pores
  • Prevents contaminants from adhering
  • Removes residue
  • Reduces fading of dyed parts

Benefits of Unsealed Type 3 Anodizing

  • Increases wear resistance.
  • Better adhesion of non-dyed parts

Post-Anodizing Dying

We apply colored dyes after aluminum anodizing. The parts undergo sealing to reduce color fading.

Colors shown are for general reference only. Other colors may be available upon request.

FAQs

Hardcoat anodizing is a proven electrochemical process that transforms a plain metal surface into an engaging exterior that provides both advanced corrosion-resistance and durability.

Industries that benefit from the use of anodized aluminum parts, including:

  • Automotive
  • Aviation & Aerospace
  • Buildings & Architecture
  • Electronics
  • Food Manufacturing / Preparation
  • Firearms
  • Home Furnishing
  • General/OEM Manufacturing
  • Marine Industry
  • Medical / Dental Equipment
  • Military / Law Enforcement
  • Sporting Goods

Our custom engineered anodizing process begins by creating a uniform aluminum oxide layer that penetrates the surface of the material. The part(s) are then placed in a sulfuric acid bath at approximately 32°F, with a density of 23 to 37 amps, for anywhere from 20 minutes to two hours. The amount of time spent submerged determines the thickness of the coating.

Benefits of engineered anodizing include: 

  • Easier to clean and maintain
  • Improved lubrication
  • Resistance to peeling, flaking, and chipping
  • Increased abrasion resistance
  • Flame resistance
  • Non-contaminating (for medical instrumentation)
