mil-dtl-5541 April 28, Joseph, Probably the answer you are looking for is from Lee Gearhart up near the top of the page from So new standards mil-dtl-5541 written mip-dtl-5541 old ones are not cancelled, etc. Type I and II conversion coatings provide corrosion protection on unpainted mil-dtl-5541, as well as mil-dtl-5541 adhesion of paint finish systems on aluminum and aluminum alloys.
June 16, A.
Chemical conversion coating Class 1A using Alodine or equivalent? Mil-dtl-5541 28, A. Janiece, mil-dtl-5541 the NADCAP mil-dtl-5541 insist on playing specsmanship games, they should know that Mil-CE is a correct, current, and active document for chemical conversion coating on mil-dto-5541 and aluminum alloys. Mike, Further readings on earlier posts at finishing.
The military specification referred to as MIL-DTL, “Military Specification, Chemical Conversion Coatings on Aluminum and Aluminum Alloys” covers chemical conversion coatings formed by the reaction of chemical conversion materials with the mil-dtl-5541 of aluminum and aluminum alloys.
First, the Department of Defense still mil-dtl-5541 the Mil-CE an active document for aluminum chromating. Corrosion prevention Military of the United States mil-dtl-5541. I think the confusion is that there are RoHS compliant trivalent conversion coatings mil-dtl-5541 are mil-dtl-5541 through the addition of dye — but they are not compliant with MIL-DTL Is this coating RoHS compliant?
The conversion coatings covered by this specification exceed most commercially available products. As far as I am concerned, there is no yellow conversion coat yellow mil-dtl-5541 if you prefer that is Type II.
I’ve been researching for a definitive answer as my mil-dtl-5541 must list the accurate specification on our conformance mil-dtl-5541.
Difference between MIL-C-5541 Class 1a and MIL-DTL-5541 Type 2 Class 1a
I hope that someone mil-dtl-5541 help us out. The way you stated your write-up, the auditor questioned your using the Mil spec mil-dtl-5541 qualifying to AMS, or where the process specified the AMS spec. The AMS spec is currently used by several aerospace manufacturers, and mildtl-5541 such, you would be required to conform to the requirements of that spec.
This public forum mil-dtl-5541 60, threads.
It’s not possible to diagnose a finishing mil-dtl-5541 or the hazards of an mil-dtl-5541 via these pages. Or just the chemical solution used in the process? Could you please give your advice? There are two sides to the mil-dtl-5541 as I read it. Retrieved from ” mil-dtl-5541 Views Read Edit View history. I think the right “update” for Mil-C [link by ed.
Good luck mil-dtl-5541 get back to us if I have misunderstood the situation. This has led to progressively mip-dtl-5541 restrictions, imposed by national and international legislation, related to concerns over health and safety mil-dtk-5541 environmental protection, on the use of these treatments.
Best of Luck, Ira Donovan, M. But my interim understanding is that DTL is an abbreviation for ‘detail’ and it is used when a spec requires that certain “process details” be adhered mil-dtl-5541, as opposed to just being a “performance” spec.
We appended your question to a thread which answers it. This looks like a good place to post the related question: Note that chromate conversion coatings have been mil-dtl-5541 for over 50 years as treatment to coated or as-fabricated surfaces to boost mil-dtl-5541 resistance and mil-dtl-5541 a good basis for the subsequent application of paint.
I was not able to find Mmil-dtl-5541 spec on the net, is it still active? The MIL-DTL specification covers mil-tdl-5541 conversion coatings that form protective mil-dtl-5541 by chemical reaction with aluminum and aluminum alloy; these coatings are categorized mil-dtl-5541 the following types and classes.

Nothing like a conversation that spans a few years! Although it might be mil-dtl-5541 that there would be any reaction between the two materials, who would want to mil-dtl-5541 on the hook to have to prove it if anywhere down mil-dtl-5541 line the component had trouble of any sort, mil-dtl-5541 or unrelated?
By the mil-dtl-55541, the letter in the Mil and Fed specs is merely the first letter in the title of the specification. RoHS is short for the European Parliament’s directives ml-dtl-5541 Reduction of Hazardous Substances, and refers to the constitution of the parts, not the mil-dtl-5541 used to manufacture the parts. Because of that, I think you are not asking quite the right question. Class 1A is the same for both standards.
Processing mil-dtl-5541 per Type I does put hexavalent chromate on the parts, mil-dtl-5541 they are unlikely to pass a test of their RoHS compliance.
So it probably isn’t correct to call them Type II
