MIL-STD-171 is the military standard that established the minimum requirements for finishing and otherwise treating, metal and wood surfaces, and to serve as a general guide to the selection of suitable finishing materials, procedures, and systems.

As the standard pertains to aluminum parts and finishes:

• MIL-STD-171, 7.2.1 calls out Anodic film on aluminum, sulfuric acid, MIL-A-8625*, Type II Class 1, non-dyed

• MIL-STD-171, 7.2.2 calls out Anodic film on aluminum, sulfuric acid, MIL-A-8625,* Type II Class 2, dyed, color to be specified

• MIL-STD-171, 7.3.1 calls out Chemical film, chromate, MIL-C-5541 Class 1A, for maximum protection against corrosion, painted or unpainted

• MIL-STD-171, 7.3.3 calls out Chemical film, chromate, MIL-C-5541 Class 3, for protection against corrosion where low electrical resistance is required

• MIL-STD-171, 7.5.1 calls out Hard anodic coating on aluminum, MIL-A-8625*, Type III, Class 1 - thickness 0.002” ± 0.0002” unless otherwise specified, non-dyed

• MIL-STD-171, 7.5.2 calls out Hard anodic coating on aluminum, MIL-A-8625*, Type III, Class 2 - thickness 0.002” ± 0.0002” unless otherwise specified, dyed, color to be specified.
