We pride ourselves on delivering high-quality aluminium products that cater to a variety of industrial, structural, and commercial needs. Aluminium 1070, part of the 1xxx series, boasts 99.7% pure aluminium, which means it offers fantastic corrosion resistance, impressive ductility, and excellent electrical and thermal conductivity. These round bars are not only lightweight but also easy to machine, weld, and shape, making them incredibly versatile for engineering and fabrication projects. At Robert Aluminium, we adhere to global quality standards, ensuring our Aluminium 1070 Round Bars are reliable, durable, and cost-effective for both local and international customers.
Aluminium 1070 Round Bars consist of 99.7% pure aluminium, with only trace amounts of silicon, iron, copper, and manganese. This alloy is known for its remarkable resistance to atmospheric, chemical, and marine corrosion. In terms of mechanical properties, it offers moderate strength, with a tensile strength ranging from 60 to 100 MPa and a Brinell hardness of about 20 HB, while also showcasing exceptional ductility and elongation. Although it can’t be heat-treated, Aluminium 1070 Round Bars respond well to cold working and shaping. With their excellent thermal and electrical conductivity, they are perfect for lightweight, durable, and cost-effective engineering, architectural, and industrial applications.
