Copper in architecture used in residential and commercial building structures. Variations in color stem primarily from differences in the alloy chemical composition. Some of the more popular copper alloys and their associated Unified Numbering System (UNS) numbers developed by ASTM and SAE are as follows: In practice, the term ‘bronze’ may be used for a variety of copper alloys with little or no tin if they resemble true bronzes in color. Further information on architectural copper alloys is available. The criteria by which copper and copper alloys are selected for architectural projects include color, strength, hardness, resistance to fatigue and corrosion, electrical and
Antimicrobial copper-alloy touch surfaces products in accordance with the U.S. E.P.A registrations. Products offered by the approved companies include sinks, computer keyboards, faucets, IV poles, tables, stretcher rails, railings, hampers, decorative and architectural hardware (levers, grips, knobs, pulls, towel bars, grab bars, kick plates, bath accessories, outlet covers, light switch covers), laboratory incubators, cabinet hardware, decorative tile, and free weights. The U.S. E.P.A. oversees a stewardship plan to promote the responsible use of Antimicrobial Copper. Further information about the making accurate claims about Antimicrobial Copper is also available. Many antimicrobial copper alloy products have been approved for registration in healthcare facilities, public and commercial
