Role and Application of Aluminum Alloys
Abstract: Alloy wheels are wheels that are made from an alloy of aluminum or magnesium. Alloys are mixtures of metal and other elements. They generally provide greater strength over pure metals, which are usually much softer and more ductile. Aircraft manufacturers use high-strength alloys (principally alloy 7075) to strengthen aluminum aircraft structures. Aluminum alloy 7075 has Copper (1.6 %), Magnesium (2.5 %) and zinc (5.6 %) added for ultimate strength, but …
