Robert Aluminium, a top-notch manufacturer and supplier located in Pulau Ujong, Singapore, takes pride in offering high-quality Aluminium 3003 Round Bars that are made in the USA. These bars are celebrated for their outstanding corrosion resistance, excellent formability, and impressive durability, making them a trusted choice across various industries. The Aluminium 3003 Round Bars are non-heat-treatable alloys that gain strength primarily through cold working, which makes them a flexible option for a wide range of fabrication needs. With meticulous engineering and a commitment to international standards, Robert Aluminium guarantees top-notch product performance, reliability, and customer satisfaction, catering to both local and global markets with premium aluminium solutions.
The Aluminium 3003 Round Bars produced in the USA are mainly made of aluminium, with manganese as the key alloying element, boosting strength while maintaining corrosion resistance. Their typical composition features 98.6% aluminium, 1.2% manganese, along with small amounts of copper and other elements. In terms of mechanical properties, they showcase a tensile strength between 130 to 200 MPa, along with good elongation and excellent machinability. These bars offer superior workability, high fatigue resistance, and great weldability, making them perfect for forming, bending, and fabrication tasks in demanding applications.
