For 60 years, CDA has served as a bridge between the people who mine and market copper, who fabricate and sell copper and copper alloy products, and those who use them in myriad applications. Those users include the scientists and engineers who develop new alloys and applications, the manufacturers of everything from mixing bowls to missile components, the architects, engineers and contractors who build buildings, the first-time homeowner enjoying her dream house, the arts organization seeking an avant-garde approach to its new complex that will showcase environmental achievement along with its sculpture, the microbrewery that wants to recreate the warmth of an old-time saloon with the efficiencies demanded by a modern brewmaster.
