Chromic Anodize, Type I+

Chromic Anodize creates a thin, corrosion-resistant oxide layer on aluminum, ideal for parts requiring flexibility and corrosion resistance. In commercial applications, it’s used for architectural components; in marine, for boat fittings; in medical, for non-critical equipment parts; in electronics, for enclosures; and in automotive, for trim pieces. CMF offers multiple seals (Hot Water, Nickel Acetate, Dichromate, PTFE).

Specifications

  • MIL-PRF-8625 Type I & IB Cl 1 & 2
  • AMS 2470
  • MIL-STD-171
Sulfuric Anodize, Type II (Multiple colors)+

Sulfuric Anodize forms a thicker oxide layer on aluminum, enhancing corrosion resistance and paint adhesion, commonly used for durable components. In commercial settings, it’s applied to consumer goods; in marine, to hull fittings; in medical, to equipment housings; in electronics, to chassis; and in automotive, to exterior parts. CMF offers colors (black, blue, red, gold, gray)  and multiple seals (Hot Water, Nickel Acetate, Dichromate, PTFE).

  • MIL-C-5541
  • AMS 2473
  • MIL-STD-171
Chromate Conversion on Magnesium+

This process applies a protective layer to magnesium, improving corrosion resistance for lightweight components. In commercial applications, it’s used for consumer electronics; in marine, for lightweight boat components; in medical, for portable device casings; in electronics, for magnesium housings; and in automotive, for lightweight brackets.

Specifications

  • AMS-M-3171 TYPE I
Passivation of Stainless Steel+

Passivation removes free iron from stainless steel, forming a protective oxide layer to prevent rust, vital for component longevity. In commercial applications, it’s used for kitchen equipment; in marine, for railings; in medical, for surgical instruments; in electronics, for connectors; and in automotive, for exhaust systems.
