I'm looking for a low cost electropolishing service in the bay area for 3 sections of 1.5" OD aluminum tubing I have. I contacted Bayshore Metals where I got the tubes from, and they told me they'd never even heard of electropolishing before. Does anyone have experience with a good electropolishing outfit in this area?
Electropolishing is electroplating in reverse. Instead of adding material to the surface, surface material is electrochemically removed. Process conditions/chemicals are selected to favor removal of protrusions (rather than the entire surface uniformly) to result in a smooth, polished look.
