Aerospace Metal Finishing

There’s no industry like aerospace, which encompasses everything from personal airplanes and commercial jetliners to military aircraft and equipment meant for interstellar exploration. These operating environments are incredibly harsh, and severe consequences can be the result when components don’t function as intended.

Take your aerospace parts to new performance levels with custom metal finishing from Harrison Electropolishing. Whether your application calls for pristine surfaces, enhanced wear resistance, or improved cycle life, we can help you deliver conforming products to customers on time and under budget.

Answers To Challenges Facing Aerospace Manufacturers

Producing the components and assemblies designed for flight is tough. Acquiring appropriate materials is hard, manufacturing tolerances are tight, and deadlines are short. What’s more, copious regulatory requirements cover part conditions and characteristics, and failing to meet them can be detrimental to your business. 

Metal finishing is just what you need to obtain optimal operational, safety, and performance. The process involves depositing metal ions onto the surface of a metallic part using an electric current to achieve a specified result. Benefits of aerospace metal finishing include: 

  • Limits Impacts Of Corrosion
  • Increases Resilience To Temperatures 
  • Promotes Paint Adhesion
  • Removes Unwanted Debris, Oils, And Greases
  • Boosts Wear Resistance
  • Stands Up To Friction
  • Polishes Substrate Surfaces
  • Improves Aesthetic Appearance
  • Supports Solderability
  • Strengthens Electrically Conductivity
  • Enhances Chemical Resistance
  • Cleans Substrate Surfaces
  • Removes Surface Defects

Also called electroplating, electrodeposition, electrochemical polishing, anodic polishing, and electrolytic polishing, this process is perfect for fragile components or those with complex geometries.

No Metal Is Beyond Our Scope

Most metals can undergo electropolishing, but optimum results are obtained from those free of non-metallic inclusions and seams or with fine grain boundaries. Metals that are regularly electropolished include:

  • Stainless Steel
  • Low-Lead Steel
  • Low-Carbon Steel
  • High-Carbon Steel
  • Tool Steels
  • Molybdenum
  • Nimonic
  • Waspaloy
  • Tungsten
  • Aluminum
  • Titanium
  • Copper
  • Kovar
  • Inconel
  • Brass
  • Columbium
  • Bronze
  • Nickel Silver
  • Beryllium
  • Monel
  • Vanadium
  • Hastelloy
  • Tantalum
  • Beryllium Copper
  • Silver and Gold
  • Cupronickel

In the aerospace industry, materials that offer high performance in a lightweight package are ideal. They’re used in conjunction with metal finishing to manufacture various parts and subassemblies, including turbine blades, struts, satellite components, panels, landing gear parts, vacuum chambers, and piping or tubing systems.
