The aluminum alloy Anticorodal 100 (AlMgSi1) is normally used in industrial engineering applications such as skyscrapers, ships and sports cars and is composed of aluminum, magnesium and silicium. This particular alloy was selected for its combined qualities of low mass inertia, endurance and dynamic strength, the special ability to absorb vibrations and a high resistance to corrosion and wear."
