Aluminium 1070 is a commercially pure aluminium alloy, featuring around 99.7% aluminium along with trace amounts of iron, silicon, and other elements. It’s celebrated for its remarkable electrical and thermal conductivity, impressive corrosion resistance, and good machinability. While the alloy has a relatively low tensile strength (about 90–130 MPa), it excels in ductility and formability. Although it can’t be heat treated, it responds well to cold working. These characteristics make Aluminium 1070 an excellent choice for applications that demand conductivity, corrosion resistance, and flexibility in fabrication, particularly in electrical and chemical settings.

Yes, Aluminum 1070 bars are corrosion-resistant due to their high purity, offering good resistance to atmospheric and chemical corrosion. However, they may be less resistant than alloyed aluminum grades.
Aluminum 1070 rods are typically sized by diameter, ranging from small diameters like 6mm to larger sizes of up to 150mm or more, with lengths commonly ranging from 1 to 6 meters.
To maintain Stainless Aluminium 1070 Bar, clean it regularly with mild detergent and water, avoid harsh chemicals, inspect for corrosion or scratches, and ensure proper storage to prevent physical damage.
Aluminium 1070 Bars and Rods find extensive use in industries where top-notch conductivity and corrosion resistance are crucial. They are commonly used in applications like electrical busbars, transformer windings, cable sheathing, and components for heat exchangers. Its formability and non-toxic properties also make it perfect for food and chemical processing equipment, packaging, and decorative applications.
