Al (Aluminum) is a lightweight, silvery-white metal known for its corrosion resistance and high strength-to-weight ratio. It is the third most abundant element in the Earth's crust and is commonly used in various applications, including packaging, construction, and transportation. Aluminum is highly malleable, meaning it can be easily shaped into different forms, and it conducts electricity well. Due to its non-toxic nature, it is also used in food containers and utensils. The metal is often alloyed with other elements to enhance its properties for specific uses.
