Metallurgical Polishing and Chemical Etching

Metallurgical polishing is a tricky business.  EPI MTG is well versed in the techniques to polish many different materials.  We have polished metals that are Iron, Nickel, and Aluminum based.  We also have experience with PCD and a variety of carbides.  We can also provide chemical and electrolytic etching of the sample after polished to a fine finish.  We have the ability to etch most all alloys from using Nital on carbon steel to molten sodium hydroxide on silicon nitride.  EPI MTG hopes to work with you in the future with your metallurgical polishing and etching needs.
