MIL spec Plating

What is MIL spec Plating?  At Gold Plating Services we provide metal finishing and gold plating for many different customers for many different reasons. Many of our customers want decorative gold plating and rely on our expertise to provide them with a type and thickness of gold plating that will best fit their purposes and budgets. We have the experience and expertise to advise them on their options. Other clients use standard specifications that define many important aspects of the plating process. For those who aren't sure of exactly what will work best for them we may suggest a specification process that will define the results they need. We specialize in plating a 24Karat gold to a specific MIL-Spec. (MIL-G-45204-C - recently superseded by MIL-DTL-45204D see below).  Plating gold to these specifications insure that the final product will meet strict purity, thickness, and hardness standards. These specifications also mandate other factors such as undercoating, adhesion and solderability. The specifications also references other MIL and ASTM standards and verification tests. Testing available upon request (additional pricing applied). We apply Mil-Spec plating to items for the aircraft, medical instrumentation industry, and electronics industry. In some cases we are applying a 24K gold plate to various grades of stainless steel and in others, we are plating onto copper, aluminum or brass alloys.  

New MIL-DTL-45204D Gold Plating Specification.  The U.S. Army Research Laboratory has developed a new specification that supersedes the MIL-G-45204C, (dated 7 June 1983), specification referenced above.  The new specification is MIL-DTL-45204D, (dated 29 June 2007), is 24 years more current and addresses questions not adequately covered by the old specification.  The classifications by Type, Grade, Purity vs. hardness, and Class are similar to the old spec, however the new specification includes standardization references to non-governmental and international, (ISO), agreements.

The new specification also has expanded quality control, testing and packaging procedures. We have this document available as a PDF file. Click Here
