Anodized Aluminum Applications: Marine Industries

Anodized Aluminum Applications: Marine Industries; Sulfuric / Chromic / Hardcoat / Clear / Color / Custom / Close Tolerance Anodizing, Custom Colors, Corrosion / Water Resistance


Superior Metal Technologies offers a comprehensive range of aluminum anodizing services to boat builders and customizers, and manufacturers of marine products, including:

  • Sulfuric Anodizing
  • Chromic Anodizing
  • Hardcoat Anodizing (Hardcoating)
  • Clear Coatings
  • Color Anodizing
  • Custom Anodizing
  • Close Tolerance Coating

Corrosion resistance and hardness are primary properties of anodic coatings, vital for metal parts that need to withstand the rigors of a marine environment, high moisture / humidity, salt spray, fuel and petroleum products, chemicals and lubricants. Anodized coatings will not chip or peel, and resists ultraviolet (UV) radiation so colors will not fade, even in direct sunlight.

Anodized Aluminum Applications: Replace Costly Stainless Steel

Anodized aluminum can replace expensive stainless steel in certain marine applications, saving future costs with it's long-lasting durability, reduced weight, and hardness and resistance properties unique to anodized products.

The ways in which anodized aluminum can be used to replace more costly stainless steel are virtually unlimited. For more information about the benefits of replacing stainless steel with anodized aluminum, read: Aluminum or Stainless Steel?

Anodized Aluminum Applications: Keep Marine Parts Ship-Shape

When dealing with salt water, or even Midwest lake water, there is always a chance of oxidation setting in. Many boat builders use a special anodized cathode built onto the lower unit of an outboard or I/O motor, designed to accept corrosion rather than the main engine component if paint gets chipped. It is designed to die before oxidation sets in to the main components.

Other uses for anodized aluminum in the marine industry include:

  • Boat Pontoons
  • Sail Pulleys
  • Porthole Frames
  • Hatch and Stairway Trimming
  • Decorative Trim

This is just a small sample of products made, in whole or part, of anodized aluminum.  Superior's highly trained specialists can help you plan, design and produce. The uses of anodized aluminum products are only limited by the imaginations of designers, inventors and engineers.
