1050 Aluminum Coil

1050 aluminum coil is an industrial base material made of pure aluminum with an aluminum content of ≥99.5%. 1050 aluminum coil belongs to the 1000 series commercial pure aluminum products. Its high purity endows it with excellent properties such as outstanding corrosion resistance, high ductility, and excellent thermal and electrical conductivity.

1050 aluminum coil is a commercial pure wrought aluminum alloy. Due to its softness and ease of formability, 1050 aluminum is widely used in industries where these characteristics are critical.

1050 aluminum coil features high plasticity, high electrical and thermal conductivity, corrosion resistance, and workability. It is commonly used in the electrical and chemical industries. 1050 aluminum alloy is also sometimes used for manufacturing radiators due to its higher thermal conductivity compared to other alloys.

1050 aluminum coil

Although the mechanical strength of 1050 aluminum coil is relatively low compared to other alloy grades, it is widely used in industries that require corrosion resistance, electrical and thermal conductivity, high reflectivity, and formability.

Due to its high-purity aluminum base, low cost, and comprehensive performance, 1050 aluminum coil is widely used in the printing, electronics, and construction industries. Its various temper states (such as H18 and H24) meet different application needs from high strength requirements to complex forming applications.

1050 aluminum coil is a soft and cost-effective material. The chemical composition and mechanical properties of 1050 alloy are relatively close to those of the 1060 series products. Since the coil made of 1050 alloy does not contain other elements, the production process is relatively simple and the price is lower, making it a commonly used series in industrial power applications. It features high plasticity, good corrosion resistance, electrical and thermal conductivity, but low strength. It cannot be strengthened by heat treatment, has poor machinability, and is suitable for contact welding and gas welding.
