WebJun 1, 2024 · A. There are definitely a couple of tricks to passing Mil-DTL-5541F, Type II, Class 1A for AL 2024, and they apply to Type I, also. First, we highly recommend using an all-purpose, non-etch light-metal cleaner. The key is it should be free of silicates. Often, sodium metasilicate is used as a builder for light-metal cleaners. The MIL-DTL-5541 specification covers chemical conversion coatings that form protective coatings by chemical reaction with aluminum and aluminum alloy; these coatings are categorized by the following types and classes. • Type I: Addresses compositions containing hexavalent chromium. This film typically appears to be gold or brown in color, but in some cases may be optionally specified as having no color (Ha…
