Aluminum alloys are materials made by combining aluminum with other elements, such as copper, magnesium, or zinc. These combinations enhance the properties of aluminum, making it stronger, lighter, or more resistant to corrosion. Aluminum alloys are commonly used in various industries, including aerospace, automotive, and construction, due to their versatility and durability. There are two main categories of aluminum alloys: wrought and cast. Wrought alloys are shaped through processes like rolling or extrusion, while cast alloys are formed by pouring molten aluminum into molds. Each type has specific applications, depending on the desired strength, weight, and resistance to environmental factors.
