Exotic Substrates for Surface Finishing

There are a range of “common” substrates and metals such as tin, copper, nickel and zinc, that any surface finishing company is most likely able to plate or anodize. These metals are considered common substrates for a reason, they are used in a majority of manufacturing applications across a multitude of industries. However, as research persists and new problems arise, the incorporation of less common, or exotic, substrates into manufacturing has become more and more frequent. These exotic substrates often possess unique physical or chemical properties that make them desirable for a specific form of application. However, with these unique properties can come an array of challenges during the plating process, chemical, physical, and financial.

Throughout our nearly 50 years in business, AOTCO Metal Finishing has perfected an abundance of finishing techniques on exotic substrates from precious metals such as gold, silver, and platinum to super alloys such as Inconel, Monel, and Kovar. On top of these super alloys, we are one of a very small group of companies that can effectively plate other metals onto tungsten and other refractory metals.

Finally, our in-house R&D team, AOTCO | LABS, is comprised of veteran plating scientists and a group of chemical and mechanical engineers dedicated to finding the most optimum solutions for your plating needs. This team, along with our entire plating staff, has turned AOTCO into one of the premier specialty plating companies in the nation.
