AMS 2469 Hard Anodize
Specifications
What is AMS 2469 | Hard Coat Anodize?
When working with our clients in the Aerospace Engineering and Advanced Manufacturing industries there is no margin for error with surface finishing processes.
AMS 2469 is the Aerospace industry standard spec for Hard Coat Anodize. The specification includes a required thickness range of 0.0020 inch ± 0.0005 (0.051 mm ± 0.013).
Benefits of AMS 2469 Hard Anodize
- Improved thermal resistance
- Provides the strongest finish of any anodizing option
- Enhanced Electrical Insultation
- Corrosion Resistance
- Abrasion Resistance
- Increased Wear Resistance
Plating Specs AMS 2469
This spec is typically used by customers looking to increase surface hardness, abrasion resistance, and/or corrosion resistance to their aluminum part.
Location of contact points to be selected by customer. If no contact points are specified, AOTCO will choose a location. When choosing these points, they should be in areas where anodizing is either optional or not required.
Sealing parts for improved corrosion resistance is optional, please specify to AOTCO if you want your parts to be sealed.
Regarding thickness, this standard requires 0.0020 inch ± 0.0005 (0.051 mm ± 0.013).
Testing
Thickness, coating weight, color, and quality are the four tests specified in this standard.

Electroplating
Electroplating
Electroplating is a process by which one metal is deposited onto a base metal (substrate). These deposited metals offer a variety of benefits including thermal and electrical conductivity, corrosion resistance and more. AOTCO electroplates a wide variety of both standard and exotic metals.

Anodizing
Anodizing
Sometimes called a “conversion coating” Anodizing is an electrolytic process in which an oxide (anodic) layer is chemically built on the surface of the substrate material, providing anti-corrosion and other benefits. AOTCO offers, Type I, Type 2, Type 3 and Titanium anodizing services.

Passivation
Passivation
Passivation is a term for a variety if processes that make a metal (most commonly stainless steel) or other substance unreactive, or passive, by altering the surface layer or coating the surface with a thin inert layer. AOTCO performs both citric and black oxide passivation techniques to a range of specifications.
