Mechanical strength is a make-or-break factor for many aluminum projects—and 3003 and 5052 aluminum differ sharply here. 3003 aluminum has a moderate tensile strength of 110–130 MPa and a yield strength of ~95 MPa, with a high elongation of 20–35%. This means it’s soft and flexible, easy to bend or stretch into shapes like lamp shades or cookware bowls.   5052...
