Alloyed with quite minor amounts of Si, Cu, Mn Mg it takes on remarkable properties. Type 6016 is stiffer, has higher tensile strength, is non-work hardening and used in aircraft fuselages. Type 3024 is so stiff I have known engineering students insist "It gotta be iron!" though it is...
These elements have lowelectrical resistivityso they are used for wiring. Copper is the cheapest and most widely used.Bond wiresforintegrated circuitsare usually gold. Silver and silver plated copper wiring are found in some special applications. ...
