Military Specification MIL-A-8625

The standard specification, MIL-A-8625 is used for much of the anodizing for military and aerospace products. It covers the requirements for six types and two classes of anodizing for non-architectural applications. It is also used for many anodizing specifications that are used for individual companies. Nearly all of proprietary specifications refer to one or more requirements of this military spec. ProTech Metal Anodizing produces products under this specification as well as base variations for proprietary use.

Increased durability under potentially harsh conditions is an important factor for any military tool or piece of machinery. Anodized aluminum provides more strength and creates an incredibly hard element which out performs any untreated metal, affording increased safety, higher performance, and more reliability. Anodizing also extends the life of equipment and provides protection against corrosion, abrasion, and chemical resistance. It is no wonder this military spec has become a standard through commercial applications as well.

The specification includes broad processing conditions for anodizing. It also outlines criteria such as coating weight, corrosion resistance, light fastness, paint adhesion, abrasion resistance, and dying. Additionally, standards are set for general appearance, workmanship, contact marks, inspection, process control, and testing.
