Overview
1050 aluminum is a commercially pure aluminum grade with minimum 99.5% aluminum content, offering excellent corrosion resistance, high electrical and thermal conductivity, and superior formability. 1050 is non-heat-treatable and is strengthened only by cold working, making it ideal for deep drawing, spinning, and stamping applications. The alloy is widely used in chemical equipment, electrical conductors, reflectors, and decorative applications.
Description (English)
1050 aluminum delivers yield strength of 85 MPa, tensile strength of 110 MPa, elongation of 30%, and excellent formability in O temper. The alloy is widely used in chemical processing equipment, electrical conductors, transformer windings, capacitor foil, architectural reflectors, and decorative products. 1050 offers the highest purity among commonly used aluminum grades, ensuring minimal contamination for sensitive applications.
