3005 aluminum foil is an alloy of aluminum that is known for its excellent strength-to-weight ratio, good corrosion resistance, and durability. It is often used in more demanding applications where higher strength than 3003 or 3004 alloys is needed, but it still retains many of the benefits typical of aluminum foil.
