Abstract

See full text

Described herein are ternary alloys of copper (Cu), aluminum (Al) and tin (Sn). For example, the ternary alloys can comprise between about 0.5 weight percent (wt %) and about 5 wt % Al and between about 0.5 wt % and about 5 wt % Sn. The chemical composition of the alloys can be tailored such that the alloy maintains antimicrobial effect over time and is resistant to tarnish. The alloys are also hypoallergenic. Articles of manufacture, particularly those for use in medical facilities, comprising the alloy (e.g., as a surface layer) are also described, as are methods of reducing the incidence of microbial infection by providing surfaces comprising the alloy.
