They cater to both local and international markets, providing top-notch aluminium solutions. Aluminium 1070, which belongs to the 1xxx series, boasts 99.7% pure aluminium and is celebrated for its excellent corrosion resistance, remarkable ductility, and outstanding electrical and thermal conductivity. These bars are not only easy to fabricate and weld but also adaptable for various industries. Robert Aluminium is committed to ensuring that their products meet strict international standards, delivering reliable, durable, and cost-effective Aluminium 1070 Bars for a wide range of structural, industrial, and commercial applications around the globe.
Aluminium 1070 Bars consist of 99.7% aluminium, with only trace amounts of silicon, iron, copper, and manganese. This high-purity alloy offers remarkable resistance to atmospheric, chemical, and marine corrosion. In terms of mechanical properties, it has low to moderate strength, with tensile strength between 60–100 MPa and a Brinell hardness of about 20 HB, while still providing excellent ductility and elongation. Although they can’t be heat-treated, Aluminium 1070 Bars excel in thermal and electrical conductivity. Their unique blend of purity, workability, and corrosion resistance makes them a reliable choice for lightweight, durable, and cost-effective engineering and industrial applications.
