Copper Fact 8Ī leaded yellow brass, C36000, also known as Copper Alloy 360 is so easy to machine, it is the benchmark standard for metals machinability. Bronzes are mainly copper along with alloying elements such as tin, aluminum, silicon or beryllium. Copper Fact 7īrasses and Bronzes are probably the most well-known families of copper-base alloys. EPA registration is based on independent laboratory tests showing that, when cleaned regularly, copper, brass and bronze kill greater than 99.9% of the following bacteria within 2 hours of exposure: Methicillin-resistant Staphylococcus aureus (MRSA), Vancomycin-resistant Enterococcus faecalis (VRE), Staphylococcus aureus, Enterobacter aerogenes, Pseudomonas aeruginosa, and E. Environmental Protection Agency as antimicrobial.* More than 350 of them have been acknowledged by the U.S. They are identified by numbers preceded by a "C" and are assigned and reviewed by the Copper Development Association for ASTM. Currently, there are more than 570 copper alloys listed with the American Society for Testing and Materials International. Copper Fact 6Ĭopper is easily alloyed with other metals. Its most important properties include superior heat transfer, electrical conductivity and corrosion resistance. It is considered a semi-precious, nonferrous, malleable metal with many hundreds of applications in the areas of electricity and electronics, plumbing, building construction and architecture, industry, transportation, and consumer and health products. Copper Fact 4Ĭopper is element number 29 on the Periodic Table of Elements. Twenty mines account for about 99% of production. United States copper production largely comes from deposits in Arizona, Utah, New Mexico, Nevada and Montana. Known land-based resources of copper are estimated to be 1.6 billion metric tons of copper (USGS, 2004). Geological Survey (USGS) estimates that every American born in 2008 will use 1,309 pounds of copper during their lifetime for necessities, lifestyles and health. It ranks third after iron and aluminum in terms of quantities consumed in the USA. And, its antimicrobial property is becoming increasingly important to the prevention of infection. It is an essential nutrient in our daily diet. It is a major industrial metal because of its high ductility, malleability, thermal and electrical conductivity and resistance to corrosion. Copper Facts Copper the Metal Copper Fact 1Ĭopper is a mineral and an element essential to our everyday lives.
