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
Tin-silver-copper been increasing. Large companies such as Sony and Intel switched from using lead-containing solder to a tin-silver-copper alloy. The process requirements for SAC solders (Pb-free) and Sn-Pb solders are different both materially and logistically for electronic assembly. In addition, the reliability of Sn-Pb solders is well established, while SAC solders are still undergoing study, (though much work has been done to justify the use of SAC solders, such as the iNEMI Lead Free Solder Project). One important difference is that Pb-free soldering requires higher temperatures and increased process control to achieve the same results as that of the tin-lead method.
