Antimicrobial copper-alloy touch surfaces follows: The following claims are now legally permitted when marketing EPA-registered antimicrobial copper alloys in the U.S.: The registrations state that “antimicrobial copper alloys may be used in hospitals, other healthcare facilities, and various public, commercial and residential buildings.” The EPA copper alloy registrations were granted “with public health claims,” meaning that they permit manufacturers of copper-based products sold in the U.S. to claim on their labels the ability of copper, brass, and bronze to kill harmful, potentially deadly bacteria. As a condition of registration established by EPA, the Copper Development Association (CDA) in the U.S. is responsible for the
Nickel Babbitt Babbitts high in tin content, consist of a relatively soft, solid matrix of tin in which are distributed hard copper-tin and tin-antimony cuboids. Babbits are often employed as a thin surface coating to obtain the advantage of their good rubbing characteristics. Nickel Babbitt Babbitt refers to a bearing alloy consisting typically of tin, lead, antimony, and copper. "XXXX Nickel" is a trade name for such an alloy that also contains a small percentage of nickel. Isaac Babbitt was issued the first patent for an alloy that was excellent for making bearings. The word Babbitt has been applied to many alloys
