    48 hours standard turnaround and 24 hour same day expedited turnaround available.

    Type II Anodizing

    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 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-A-8625F
    Eaton Specification: ACES-1758P1
    Sampling Plan: MIL-STD-105E
    Tank Size: 48x24x38
    Max Part Size: 46x21x36
    Processing Time: 48 hours
    Minimum Lot Charge: $50.00/$150.00 (Two Tone)

    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. Great Lakes Metal Finishing offers Aluminum Oxide 180 Grit Blast and Aluminum Oxide of various grit-blasts to accommodate any customer need. Other grit sizes and media may be available for an additional charge.

    Work Area: 12x12x12
    Max Part Size: 12x12x12
    Processing Time: 48 hours
    Minimum Lot Charge: $25.00

    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.

    Mil-DTL-5541 (5S41?) Type I (hexavalent chrome) and Type II (tivalent). ROHS compliant for Type II.

    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.

    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

    Tank Size: 42x17x32
    Max Part Size: 40x15x25
    Processing Time: 48 hours, but processing time for orders requiring humidity testing shall be 72 hours.
    Minimum Lot Charge: $40.00

    *Please call for other applicable specifications.
