Aluminum alloys are materials made by combining aluminum with other metals to enhance its properties. These alloys are lightweight, strong, and resistant to corrosion, making them ideal for various applications, such as in the automotive and aerospace industries. Common alloying elements include copper, magnesium, and silicon, which improve strength and durability. There are two main types of aluminum alloys: wrought and cast. Wrought alloys are shaped through processes like rolling or forging, while cast alloys are poured into molds. Each type has specific uses, with wrought alloys often found in aircraft and automobiles, and cast alloys used in engine components and furniture.
