Copper Alloy is a material mixture of primarily copper and other elements in smaller quantities. There are different types of copper alloys. The Copper Alloy types can be categorized as copper alloys, brass, phosphor bronze, aluminium bronze, silicon bronze, cupronickel and nickel silver alloys as well. The categorization is based on the Copper Alloy composition. Zinc is the major addition in brass, Tin in phosphor bronze, aluminum in aluminum bronzes, silicon in silicon bronzes and nickel in nickel silvers and cupronickel alloys. The Copper Alloy density differs from category to category. They are all used in different capacities and applications. The applications of the alloys include in the manufacturing of wires and cables, electronics and related devices, folk medicine, speculative investing, antimicrobial applications, architecture and in electric motors as well. The Copper Alloy properties include high corrosion resistance, high thermal conductivity and high electric conductivity. Some of them are annealed, some cold drawn, cold rolled, spring tempered, annealed solution treated and cast. The differences in the making in each different alloy are governed by Copper Alloy standards. There are different grades in different categories. For example the beryllium copper is annealed solution treated and has 45% elongation. The Copper Alloy specifications differ from grade to grade and from standard to standard. The beryllium alloy for example is used in electrical valves and pumps, mold making, robotic welding, oilfield tools and in aerospace landing gears. The Copper Alloy suppliers sell copper alloys of different grades and standards for different applications. There are specific alloys that are used in specific applications as well. The gilding metal ASTM B36 for example is used for making coins and bullet jackets. The prices are given in per kg measures. We can provide any customers with a fully comprehensive Copper Alloy price per kg upon request.
