This alloy is mechanically similar to Alloy 110, but it also exhibits superior formability . If the term flexible is singularly used, it implies flexible but inelastic. Copper is also corrosion-resistant (it does not rust very easily). This method is generally recognized as the earliest technique for creating wire. RE: heat treating copper (wire) heating makes the metal brittle" have a grain of truth to them. Aluminum wire is more easily oxidized than copper wire, and the compound formed by this process - aluminum oxide - is less conductive than copper oxide. This native copper was first used (c. 8000 bce) as a substitute for stone by Neolithic (New Stone Age) humans. As a result, copper is often used in products designed to last a lifetime, or longer. If metal is beaten into sheets, then it is malleable, and if made into wires, then ductile. Part 2Heating the Copper Download Article.
