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
2195 aluminium alloy 2195 aluminium alloy 2195 aluminium alloy is an alloy in the wrought aluminium-copper family (2000 or 2xxx series). It is one of the most complex grades in the 2000 series, with at least 91.9% aluminium by weight. Like most other aluminium-copper alloys, 2195 is a high-strength alloy, with bad workability, and poor corrosion resistance. Being highly alloyed, it tends to fall on the higher strength and lower corrosion resistance side. As a wrought alloy, it is not used in casting. It can be welded, and is fracture resistant at cryogenic temperatures. It is one of the Weldalite family of aluminum-lithium
