Aluminum Alloy 7178, comprised of copper and magnesium as its primary alloying elements, offers uncompromising strength and accommodates a number of different metalworking processes. These processes include machining, welding, and heat treating. AluminumÂ 7178 is stocked by 2 North American distributors and produced by 11 large mills. Distributors will offer small quantity buys while mills will generally only sell large quantities, with delivery times anywhere from 10 to 50 weeks depending on size and form required
Alloy 7178 offers good machinability and also responds well to resistance welding. Heat treatment should be performed at 875 Â°F with a subsequent water quenching. After treatment, this alloy gains precipitation hardening which improves its mechanical properties. Heavier thicknesses are formable.This alloy is preferred for many applications in the marine, construction and aerospace industries. Aluminum Alloy 7178 from Continental Steel and Tube Company meets or exceeds all relevant industry standards. These standards include all appropriate ASTM, QQ, SAE, and UNS specifications.
