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.
