Aluminium 3003 Circles are primarily made up of 98.2% aluminum, along with manganese (about 1.0–1.5%) and small amounts of copper, iron, and silicon. This unique blend provides the alloy with outstanding corrosion resistance, moderate strength, and excellent workability. In terms of mechanics, it boasts a tensile strength of around 130–180 MPa and a yield strength of approximately 55–95 MPa, with elongation varying from 12–25%, depending on the temper. The alloy’s remarkable forming capabilities allow it to be easily bent, rolled, or drawn into circles without cracking. Its moderate hardness and exceptional resistance to atmospheric corrosion make it perfect for both structural and decorative uses.
