Because of its excellent galvanic corrosion resistance, MICRALOX micro-crystalline aluminum oxide coating is the ideal coating for aluminum parts and components used in marine applications. Traditionally, aluminum is used by marine OEMs because of its excellent strength-to-weight ratio. However, the lifetime performance of aluminum components is limited due to the material’s potential for corrosion.

With the addition of MICRALOX micro-crystalline anodic coating, aluminum parts can withstand harsh, corrosive marine environments. And, MICRALOX-coated aluminum is more economical than other popular materials such as stainless steel.


Examples of aluminum marine hardware and components that can benefit from MICRALOX micro-crystalline aluminum oxide coating include, but are not limited to:

  • Fasteners
  • Rivets
  • Doors
  • Fuel Tanks
  • Covers
  • Deck Hardware
  • Dock Hardware
  • Stairs
  • Hatches
  • Exhaust Manifolds
  • Wheels

While numerous anodic coating solutions have been developed to protect aluminum substrates, few of the successful candidates are RoHS compliant. Those that are often require expensive primers and coatings that are prone to delaminating and/or don’t provide high levels of abrasion resistance to complement their corrosion-resistant properties. MICRALOX micro-crystalline anodic coating requires no primers or additional coatings, and is proven by an independent testing laboratory to withstand more than 10,000 of rigorous salt water spray testing—more than 30 times the standard for conventional anodic coatings!
