Aluminum Alloys 5000 and 6000 are widely available materials used for aircraft fittings, couplings, electrical fittings and connectors, hinge pins, magneto parts, pistons, appliance fittings, valves and valve parts. These alloys have excellent joining characteristics and good acceptance of applied coatings. These materials combine relatively high strength, good workability and high resistance to corrosion.
