The time of contact killing listed among the different microbes ranges from 1 minute to over a week. I don’t know which example of a microbe would be closest to copper.
One big problem that may exist with using copper that I came across is that copper may reduce in efficacy if it is frequently cleaned, whereas stainless steel is fine to repeatedly clean. Source
The cleaner suggested to be used on copper surfaces without reducing its efficacy by this paper .
The document referring to copper that I found via SSC was https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3067274/ .
