Zinc or Anodized


What would be better to use to connect copper electrical buss, zinc or anodized bolts. What is the differences and benefits on either for electrical connections.

The answer depends on what you are doing with the bus bar. If it is on a plating tank use stainless steel anything else is just not up to the job.

Agreed. In fact if it's anywhere in a plating shop at all, neither zinc plated nor aluminum should be considered. Hardware is available fabricated of certain copper alloys that carry current better than stainless and which are corrosion resistant, but if the bolts don't need to carry current, stainless steel is always your best best.
