Understanding Specification AMS 2451C


Understanding Specification AMS 2451C

SAE International (SAE) is an association and standards developing organization for engineering professionals in various industries. SAE has more than 128,000 engineers and related technical experts in the aerospace, automotive and commercial-vehicle sectors. It is their mission to “advance mobility knowledge and solutions for the benefit of humanity.”

In 1998, SAE wrote the AMS 2451 standard for the general requirements of brush plating. As Mil-Std 865 is now inactive for new designs, AMS 2451C – revised in 2011 – serves as its replacement. While similar to AMS 2451C, Mil-Std-865 was more specific. Mil-Std-865 covers the process and materials for the brush plating of various metals and alloys on ferrous alloys, aluminum alloys, copper alloys, nickel alloys and corrosion-resistant steel, etc. But an advantage to the new AMS 2451C standard is within the specification some of the most used and accepted tank standards – such as AMS 2403, 2423, 2424, Mil-Std QQ-P-416 & Mil-Std QQ-S-365 – are listed and referenced. Technicians now have the opportunity to perform brush plating to several of the well-known AMS and Mil-Std tank specifications.

Brush plating is a portable surface finishing method used to enhance, repair, and refurbish localized areas on manufactured components. The SIFCO Process® is the leading portable method of brush plating localized areas without the use of an immersion tank. It is primarily used for enhancing surfaces on OEM components, permanent repairs and salvaging worn or mis-machined parts.

Do you have a valid AMS 2451C application?

If you can answer yes to the following questions, brush plating may be an option for you:

  • Have you plated to AMS 2403, 2423, 2424, Mil-Std 865, Mil-Std QQ-P-416 or Mil-Std QQ-S-365 in the past?
  • Do you have a selective or localized area that needs plating?
  • Is there a time/cost/quality issue specific to your application?

AMS 2451C has 14 slash number for individual deposits covering nickel, cadmium, copper, silver, zinc-nickel, tin-zinc, cobalt, tin, and nickel tungsten. While it is significant that brush plating has gained formal recognition by SAE, it remains very generic in regard to the application of the process.
