Copper the Metal :
Copper is a mineral and an element essential to our everyday lives. It is a major industrial metal because of its high ductility, malleability, thermal and electrical conductivity and resistance to corrosion. It is an essential nutrient in our daily diet. And, its antimicrobial property is becoming increasingly important to the prevention of infection. It ranks third after iron and aluminum in terms of quantities consumed in the USA….
Copper in History :
Copper is man’s oldest metal, dating back more than 10,000 years. A copper pendant discovered in what is now northern Iraq goes back to about 8700 B.C….
Copper in Health :
Copper is essential in the human diet. It is needed for the normal growth and development of human fetuses, infants and children. In adults, it is necessary for the growth, development and maintenance of bone, connective tissue, brain, heart and many other body organs. Copper is involved in the formation of red blood cells, the absorption and utilization of iron, and the synthesis and release of life-sustaining proteins and enzymes. These enzymes produce cellular energy and regulate nerve transmission, blood clotting and oxygen transport. Copper is also known to stimulate the immune system, help repair injured tissues and promote healing. Copper has been shown to help neutralize “free radicals,” which can cause severe damage to cells….
Antimicrobial Copper :
In February 2008, the U.S. Environmental Protection Agency (EPA) approved the registration of 275 antimicrobial copper alloys. By April 2011, that number expanded to 355. This permits public health claims that copper, brass and bronze are capable of killing harmful, potentially deadly bacteria. Copper is the first solid surface material to receive this type of EPA registration, which is supported by extensive antimicrobial efficacy testing. *…
Natural Resource Copper :
We’re in no danger of running out of copper. Worldwide resources of this important and valuable metal are estimated at more than 8.1 trillion pounds of which only about 1.1 trillion (~13.6%) have been mined throughout history….
Copper In Architecture :
Copper has played an important role in the design and architecture of all types of structures for thousands of years. In ancient Egypt, the massive doors to the temple of Amen-Re at Karnak were clad with copper. The 162-foot-tall, nine-story Loha Maha Paya temple built in the third century B.C. in Sri Lanka sparkled with copper roof shingles. Copper was an integral part of European medieval architecture and today, some 10,000 years after it was first discovered by mankind, architects and building designers are finding new and innovative ways to use copper in their designs….
Electrical Products with copper :
Copper is the standard benchmark for electrical conductivity. It conducts electrical current better than any other metal except silver….
Electronics and copper :
IBM and others are using copper instead of aluminum in the most powerful computer chips they manufacture. Because of copper’s superior electrical conductivity, this technology enables conductor channel lengths and widths to be significantly reduced. The result is much faster operating speeds and greater circuit integration – 400 million transistors can be packed onto a single chip. Power requirements are now reduced to less than 1.8 volts, and the chips run cooler than ever before….
Copper in Communication :
Not long ago, it was thought that only fiber optics could handle big bandwidths. Not so. Communication between computers can now achieve data speeds up to 10 gigabits per second on twisted pairs of copper wire called structured wiring….
Copper in Plumbing :
Archeologists recovered a portion of the water plumbing system from the Pyramid of Cheops in Egypt. The copper tubing used was found in serviceable condition after more than 5,000 years….
Copper in the Home :
Building construction accounts for nearly half of all copper use. Residential construction is about two-thirds of the building construction market…
Copper in Household Products :
Most silver plate flatware (forks, knives, spoons) has a copper-nickel-zinc alloy base (nickel silver) which accounts for about 1.2 pounds of copper per set of 12 pieces. An average set of hollowware uses about 1.8 pounds of copper….
Copper in Transportation and Industry :
There’s more than 50 pounds of copper in a typical U.S.-built automobile: about 40 pounds for electrical and about 10 pounds for nonelectrical components..
Consumer Products with copper :
Copper alloys were used in even the oldest of musical instruments. Bronze cymbals date back over three millennia to Assyria. The Chinese created copper-alloy trumpets and bronze chimes 2,200 years ago. The first trumpets made of copper alloys in the West, created by the Greeks and Romans, are about 2,000 years old. However, the oldest trumpets, perhaps made of animal horns and tusks, were created in Egypt nearly 4,000 years ago….
Copper in Art :
Copper and its alloys have been used throughout the ages for artistic pursuits. Due to the metal’s unique physical properties, it can be manipulated into various shapes, designs and structures of all sizes. And, it looks good. Today, copper fixtures and decorative copper finishes are an exciting trend in home décor and can be found on everything from small appliances to refrigerators, countertops, fireplace surrounds and more….
