Anodize

A durable, non-conductive oxide layer that protects, strengthens, and enhances aluminum surfaces.

An essential finish for corrosion resistance, aesthetics, and high-wear applications — especially in aluminum parts.

What Is Anodizing?

Anodizing is an electrochemical surface finishing process primarily used on aluminum and other nonferrous metals such as titanium and magnesium. The process converts the metal surface into a durable, corrosion-resistant oxide layer that is fully integrated with the substrate.

In addition to enhancing durability and surface hardness, anodizing improves wear resistance and enables color customization through dyeing, thanks to the porosity of the anodized layer.

Types of Anodizing

Type I

Chromic acid anodizing: thin and flexible; used in aerospace for minimal fatigue impact

Type II

Sulfuric acid anodizing: most common; balances corrosion resistance and cost

Type III

Hardcoat anodizing: thickest and hardest layer; best for industrial and high-wear applications

Characteristics and Benefits

  • Corrosion Resistance: Protective oxide layer prevents oxidation
  • Wear Resistance: Harder surface improves durability
  • Electrical Insulation: Non-conductive barrier ideal for electronic housing
  • Aesthetic Appeal: Can be dyed in a variety of colors for branding or appearance
  • Surface Hardness: Especially high with Type III, enhancing mechanical performance

Common Applications

  • Aerospace and defense components
  • Consumer electronics and enclosures
  • Automotive trim and engine parts
  • Architectural structures
  • Industrial machinery and tooling
