Antimicrobial properties of metals
Certain metals, such as copper, silver, and their alloys, have been shown to kill bacteria and inactivate viruses. Under the right conditions, corrosion will trigger these antimicrobial properties without any human intervention needed. High-touch surfaces made with these metals and alloys can help minimize the spread of disease in places such as hospitals or public transportation. Copper and silver can also help minimize bacteria in water storage containers. There is more to learn about the application of copper, silver, and their alloys to unlock their full potential to help keep us healthy.
