When it comes to jewelry, copper is definitely less valuable than gold or silver. In the world of assembly, however, copper is much more in demand. Its uses range from electrical conductors in wire, to solar-cell foundations, to sheet metal products for commercial and residential applications.
Since 1980, Thunderbird Products has specialized in manufacturing high-quality copper products such as drains, vents and flashings. Based in El Cajon, CA, the company was the first to create a seamless copper roof drain, and it currently offers more than 700 products made of copper, stainless steel and TPO (thermoplastic olefin)-cladded metal.
