Benefit

Type I Chromic Acid Anodizing passes an electrical flow (anodizing) through a chromic acid solution. This creates a thin aluminum oxide film that is non-reactive, a good primer base, and corrosion-resistant. This is a favored coating for parts undergoing high-stress, such as in the aerospace industry.

Features:

  • For aluminum with copper content below 5%.
  • Thin but has greater abrasion resistant surface than bare aluminum. (Thicknesses range from .00005" to .0001".)
  • Very corrosion resistant coating for the small thickness.
  • Provides an exceptional base for primers, bonding agents, and organic coatings.
  • Provides nonreactive surface for metal-to-metal contact interfaces such as welded or riveted assemblies.
  • Provides nonreactive surface for metal-to-elastomer contact interfaces

Note: We provide Chromic Anodizing Type I, Sulfuric Anodizing with Color - Type II, Hard Anodizing Type III, and Sulfuric Anodizing - Type II.
