1. A method of processing an aluminum alloy coil, the method comprising:
a tempering process including:
performing a first reel-to-reel process, the first reel-to-reel process comprising:
rolling the aluminum alloy off a first feed reel, annealing the aluminum alloy to solutionize the aluminum alloy, quenching the aluminum alloy, and passing the aluminum alloy to a take up reel to form an annealed aluminum alloy coil;
performing a second reel-to-reel process comprising rolling reduction and roll cladding a contact metal onto the aluminum alloy to form a cladded aluminum alloy coil; and
performing a precipitation hardening heat treatment on the cladded aluminum alloy coil, wherein the cladded aluminum alloy coil has a tensile strength of greater than 42 ksi and yield strength of greater than 35 ksi; and
performing a third reel-to-reel process comprising electroplating a contact metal on the cladded aluminum alloy coil formed by the tempering process.
