This beautiful Beaux-Arts build-ing is lavishly decorated with marble and brass, an antimicrobial alloy, and opened to the public over a century ago. The pure copper+zinc alloy called "brass" has three types based on different crystal structures, as discussed in a previous post. Gold Vs. Brass. You have to keep in mind that copper while it looks nicer is more pure but also more malleable, and for the purposes of a paperweight, you would . However, this material has a higher aesthetic quality as it bears a strong resemblance to gold. Brass also gains excellent machinability thanks to another alloy element: ammunition. Ancient civilizations exploited the antimicrobial properties of copper long before the concept of microbes became understood in the nineteenth century. The Hippocratic Collection, a compilation of early medical writings associated with Hippocrates (460 to 380 B.C. Copper Facts: Antimicrobial Copper Copper Fact 1 In February 2008, the U.S. Environmental Protection Agency (EPA) approved the registration of 275 antimicrobial copper alloys. Copper and copper-based alloys including brasses (Cu-Zn) and bronzes (Cu-Sn) are . Pro: Unmatched in Style and Quality. While the phenomenon was already known in ancient times, it is currently receiving renewed attention. Copper, brass, and bronze all belong to the same metal category, but each of them have distinct characteristics, which makes different alloys better for different projects. . They have an inherent ability to kill a wide range of harmful microbes relatively rapidly - often within two hours or less - and with a high degree of efficiency. According to the EPA, copper can "leach into water primarily from pipes, but fixtures, faucets (brass) and fittings can also be a source." 5. It is highly resistant to weathering and is ideal for use in corrosive environments. For example, it can be built into an outdoor deck or turned into an infinity pool. Brass as a metal is stronger and stiffer compared to copper. It is more ductile than bronze and exhibits similarly low friction when in contact with other metals. It is essential for things like cell respiration, neurotransmitter synthesis, and the cross linking of collagen and elastin in the skin. ), recommends the use of copper for leg ulcers related to varicose veins.
