Sulfuric Anodize - Type II
(Clear or Dyed)                     

   Anodizing is an electro-chemical process that
thickens and toughens the naturally occurring
protective oxide. It is strictly a process applied to
aluminum alloys. Most aluminum alloys can be
processed, though those with a low copper content
(less than 3.5%) and a low silicon content (less than
5%) are recommended. Alloys experiencing the best
results are 6061, 6262, 7075 wrought alloys; 355,
356 cast alloys; 319 die cast alloys.

Microsheen is a Proud Member of PMA

Key Benefits

1) Anodize resists corrosion.
     Tests reveal that 6061 aluminum, after the anodizing process, withstood
     corrosion for 336 hours in a 5% salt spray test. Results will vary based upon
     the alloy of the material and the prior surface finish.

2) Anodizing provides good abrasion resistance.
     Though there are more durable finishes, anodize provides sufficient protection
     against ultraviolet conditions, weather, and corrosion.

3) Anodize can be color dyed in colors of Black, Green, Gold, Red, and Blue.
     This provides an attractive and easily identified part that is more attractive to
     you or your customers.

  • Some dyes provide a permanent fade resistant color for long lasting outdoor
    exposure in architectural and other similar applications.
  • Other colored dyes provide an attractive, sales enhancing decoration and
    enhances consumer products for indoor use.
  • The dyes can also be utilized during in-house processing for easy part


  • Dissimilar Materials; Aluminum parts having dissimilar materials installed
    in them such as bushings, dowel pins, etc. should be installed after the
    anodizing process.

  • Certification: Microsheen Type II anodizing meets MIL-A-8625 specifications.

  • Conversion Coating / Iridite / Alodine

    Conversion Coating provides the following benefits;

    1) It provides corrosion resistance on aluminum sheets, stampings,
        extrusions, forgings and aluminum castings without anodizing or any other
        pre-coating processes. While results vary depending on material alloy and
        surface finish, tests indicate conversion coating can resist corrosion in a
        5% salt spray tank for 168 hrs.

    2) Conversion Coating provides a good paint base, and also provides nearly
        zero electrical resistance. Since the coating and seal are not applied
        electrically and can be applied quickly, Conversion Coating can prove to
        be one of the most cost-effective methods to provide a base primer prior
        to applying paint and surface coatings.

    3) Conversion Coating prolongs shelf life of parts while resisting staining and

    4) It provides corrosion resistance on aluminum products by converting the

    5) Conversion Coating may be applied in a clear or gold finish, depending on
        your individual preferences and requirements.

         Microsheen Conversion Coating meets MIL-C-5541 specifications.
