Electropolishing & Deburring Service for Copper Alloys

Companies around the world submit their machined parts made from copper, for Able’s signature electropolishing treatment. Our electropolishing process enhances the functionality of parts by improving the microinch finish and leaving them free from harmful burrs. The parts are left in an ultraclean, passive state, which protects the finish from oxidation.

Benefits of Electropolishing for Copper

Electropolishing is an effective pre-plate finish for copper alloys.  After electropolishing the edges are deburred and slightly radiused, minimizing the plating build up on the edges.  The smooth, radiused surface is more conductive and the current is uniform with the spiking eliminated.  Many of our customers electropolish electrical contacts prior to gold plating.

Electropolished Copper Case Study

A current customer sends us multiple beryllium copper contacts for a 2-way radio.  Their end customer was having performance problems due to poor conductivity.  Able solved the problem by electropolishing the parts and removing the die break around the edges prior to plating.
