Type II Anodizing / Type III Hardcoat

This is a sulfuric acid process that forms a protective film of aluminum oxide on the surface of the metal. This coating produces a medium to hard protection, making the aluminum less susceptible to damage and corrosion while generating an electrically non-conductive exterior. Sulfuric Anodize Type II / Type III provides:

  • Corrosion Resistance
  • Decorative/Cosmetic Appearance
  • Stain Resistance
  • Increased Durability / Lubricity
  • Non-Electrical Conductive Surface
  • Type II Class 1: Non-dyed
  • Type II Class 2: Dyed – Red, Blue, Yellow, Black, Olive, Brown, Green, Orange, Violet, and Custom Colors (please call for availability)
  • Specification: MIL-PRF-8625F (2)
  • Eaton Specification: ACES-1758P1
  • Sampling Plan: MIL-STD-105E
  • Processing Time: 48 hours
  • Quoting Available
chemical conversion coating

Chemical Conversion Coat

This process of coating provides excellent corrosion protection and acts as a base for painting. There are two classes of coatings, Class 1A and Class 3.

  • Class 1A Coatings provide corrosion protection and paint finish adhesion to unpainted 100% aluminum and aluminum alloy surfaces.
  • Class 3 Chemical Coatings provide a corrosion preventive film for electrical and electronic applications where low resistance contacts are required.
  • Mil-DTL-5541 (5S41) Type I (hexavalent chrome) and Type II (tivalent). ROHS compliant for Type II.
  • Eaton Spec ACES 16P5 and 16P68
  • Quoting Available
passivation services

Passivation

Quality Passivation at competitive prices ran to AMS 2700 Type 2 and Type 7. The main purpose of this process is to remove free iron from the surface of stainless steel parts that will be deposited during the manufacturing process. This helps prevent rust and can make parts look better with no dimensional change. Passivating with nitric acid will remove the free iron and remove contaminant residue, allowing the stainless steel to set up its own corrosion barrier.

  • Specification: AMS 2700E Type 2 & Type 7
  • Eaton Specification: ACES-16P50 (Type 2); ACES-16P51 (Type 7)
  • Sampling Plan: AMS 2700E
  • Processing Time: 48 hours, but processing time for orders requiring humidity and water immersion testing shall be 72 hours.

  • Please call for other applicable specifications
phospate coating

Phosphate Coating – Titanium

GLMF offers phosphate coat that complies with AMS 2486. Call for competitive pricing.

  • Specification: AMS 2486E
    Eaton Specification: ACES-16P21
  • Sampling Plan: AMS 2486E
  • Processing Time: 48 hours

blast services

Blast & Micro Blast

This process prepares the surface for non-reflective matte finishes and paint adhesion. Blasting can also remove anodize for additional processing such as chromate conversion coating. ĢƵվ offers Aluminum Oxide 180 Grit Blast and Aluminum Oxide of various grit-blasts to accommodate any customer need.

  • Processing Time: 48 hours
  • Quoting Available
  • Other grit sizes and media may be available for an additional charge.

Multi-Process

Many projects require more than one of the processes listed above. In such a case, ĢƵվ offers multi-process operations to meet your needs no matter how complex. GLMF offers various masking techniques, Two Tone, and Micro-blast.

Paint & Dry Film
