What Exactly is Aluminum Alloy Sheet Metal?

Before we go any further, it’s crucial to have a basic understanding of what aluminum alloy sheet metal is. Essentially, it’s a composite material consisting of pure aluminum (the base metal) and other elements that enhance its properties. These additional elements can be copper, magnesium, silicon, or zinc, to name just a few. Combining aluminum with these other elements results in an alloy with improved strength, corrosion resistance, and various other properties.
