What is 1100 aluminum considered to be?

1100 aluminum is considered to be a commercially pure aluminum alloy. It is characterized by its high aluminum content, typically 99.0%, and is known for its excellent corrosion resistance, good thermal conductivity, and high electrical conductivity. The absence of other alloying elements makes 1100 aluminum highly ductile and easily workable, allowing for various fabrication processes such as bending, forming, and welding. This alloy is commonly used in applications that do not require high strength but prioritize corrosion resistance and formability, such as chemical equipment, food processing containers, heat exchangers, reflectors, signage, and general sheet metal work. It is also widely used in electrical conductors and transformer windings due to its high electrical conductivity.
