Diamond E.N.™

Diamond E.N.™ is our toughest coating yet, plating at 57 RC and reaching 70 RC after post-bake. It offers an extremely low coefficient of friction, which means it can take on all your wear and release issues at once.

A Powerful Nickel Coating

Diamond E.N.™ combines Electroless Nickel with diamond particles, making it a solid alternative to Hard Chrome for saving on time and cost.
