The automobile industry uses aluminum to manufacture the frame and body, wires, wheels, lamps, paints, transmissions, air-conditioning condensers and pipes, engine parts (pistons, radiators, cylinder heads) and magnets (for speedometers, tachometers and airbags).
6061 alloy is a heat treatable alloy with good corrosion resistance. This aluminum alloy includes plates, sheets and extrusions, including customized shapes. 661 aluminum is usually used to manufacture automobile parts, which has a high strength-weight ratio.
Special-purpose wheeled vehicles have standard military functions or characteristics that are outside normal commercial requirements.
Aluminum 5052 5754 alloy sheet and 6061-T6 and 6063-T5 extrusions are employed extensively in the bodies of large buses, cargo trailers, liquid-transport tanks, and comparable vehicles.
