Aluminum cans are not 100% aluminum, but are made of aluminum alloys. This alloy is made of aluminum mixed with other metal elements (such as copper, magnesium, manganese, etc.) to improve the performance of aluminum and reduce costs. This is because the density of aluminum is about 1/3 of that of stainless steel, which makes aluminum cans much lighter while ensuring strength. Aluminum alloys have good ductility, corrosion resistance and plasticity, making them very suitable for making cans.
