Surface Treatment Materials

Catering to a wide variety of client needs and uses AOTCO finishes on more than two dozen Common, Exotic and Non-Metallic substrates.

Depending on the base material we regularly pass 300 degrees Celsius and in some cases as high as 450 degrees Celsius after plating. This allows for high temperature soldering, brazing, or post machining operations after plating. Please inquire about any special applications that you may require.

As you might imagine, the many combinations of substrates and finishes result in a wide variety of performance characteristics. If you’re puzzling through which combination will be best for your particular design goals please give us a call.

Our R&D team loves working with clients both for new product design and for periodic product optimization reviews. Involving AOTCO’s experts early on often results in time and money saved by the end of the project.

And if you do not see your preferred substrate material listed, please reach out and speak with us. We love a challenge and always welcome the opportunity to create new processes for plating on new materials and geometries.
