Post Processing

Finishing Options for Sheet Metal

Minimal post-processing or treatment on parts is done.
The part surface is left with a smooth, matte appearance.
Type II (MIL-A-8625, Type II) creates a corrosion-resistant finish. Sheet metal parts can be anodized in different colors—clear, black, red, and gold are most common—and are usually associated with aluminum. Type III (MIL-A-8625, Type III, Class 1/2 "hardcoat") is thicker and creates a wear-resistant layer in addition to the corrosion resistance seen with Type II.
This sheet metal finish provides corrosion resistance and good conductivity properties. Chem film can be used as a base for paint and can leave surfaces yellow or gold. Adds very little thickness, about 0.00001”-0.00004.” Chem film will conform to MIL-DTL-5541, TYPE I/II.
This is a sheet metal fabrication process where powdered paint is sprayed onto a part that is then baked in an oven. This creates a strong, wear- and corrosion-resistant layer that is more durable than standard painting methods. A wide variety of colors are available to create the desired aesthetic. See examples of our options in our powder coating finishes gallery.
A sheet metal fabrication process that provides uniform nickel coating which offers protection from corrosion, oxidation, and wear on irregular surfaces. The finished part will be brighter. Thickness starts at .0001” and this finish conforms to MIL-C-26074.
Gold Plating provides good corrosion and tarnish resistance with excellent solderability. Default application specification is MIL-G-45204 & ASTM B488, CLASS 00, 0, OR 1 (Thickness 0.00002" - 0.00005").
Silver offers high solderability and electrical conductivity but is susceptible to tarnish on sheet metal parts. Conforms to AMS QQ-S-365D. Thickness is about 0.00002”- 0.0003.”
