1050 aluminum belongs to the 1000 series aluminum alloys, which means it is essentially pure aluminum with a purity of at least 99.5%. It is known for its excellent corrosion resistance, high ductility, and high reflectivity. Due to its relatively low mechanical strength, it is typically used in applications where high strength is not the primary requirement, but good formability, conductivity, and surface appearance are important.
1050 aluminum (also known as 1050A) is a commercially pure aluminum alloy known for its high ductility, excellent corrosion resistance, and high reflectivity. It is widely used in applications where formability and conductivity are more critical than strength. Common applications include chemical processing equipment, food containers, building waterproof panels, lamp reflectors, and cable sheathing.
