Brasses containing at least 70% copper were very effective at inactivating HuCoV-229E (Fig. 2A), and the rate of inactivation was directly proportional to the percentage of copper. Approximately 103 PFU in a simulated wet-droplet contamination (20 µl per cm2) was inactivated in less than 60 min. Analysis of the early contact time points revealed a lag in inactivation of approximately 10 min followed by very rapid loss of infectivity (Fig. 2B).
Here’s a study using a different coronavirus.

HCOV-19 is a (unusual?) name for the nCOV/SARS-CoV-2 virus responsible for COVID19. It’s the one in red.
