Aluminum anodizing is an electrochemical procedure for producing a corrosion resistant coating of aluminum oxide on most aluminum alloys. Keystone's Aluminum Anodizing combines the advantages of aluminum's light weight, machineability and low cost with superior corrosion and wear resistance.

Keystone Aluminum Anodized offers high dielectric strength which will accept dyes readily, allowing them to offer both decorative and highly functional properties at the same time.



Keystone offers the following processes for aluminum anodizing and its alloys:


  • Sulfuric Acid
  • Clear
  • Fluorocarbon Seal (Teflon)
  • Black Dye

Dyed coatings tend to be 0.0006 to 0.0008 in. thick while the thickness of clear or non-dyed films typically run 0.0002 to 0.0004 in.



Aluminum anodizing has proved invaluable in countless industrial and military applications. Your designers can select the alloy characteristics you require and then specify Keystone Aluminum Anodizing for finishing. Some traditional uses of Keystone Aluminum Anodizing include:


  • Machinery
  • Electronics
  • Architecture
  • Aerospace
  • Military
