As a non-heat-treatable wrought alloy, 3003 derives its strength from cold working rather than precipitation hardening. Square bar is typically produced by extrusion (in H112 or F temper) or fabricated by cutting from strain-hardened sheet or plate stock (in H14, H22, or O temper).<\/p>\n<p>With 1.0\u20131.5% manganese as its primary alloying element, 3003 offers approximately 20% higher strength than commercially pure 1100 aluminum while retaining excellent corrosion resistance, formability, and weldability. Square bar is widely specified for structural framing, machining blanks, decorative applications, tank supports, and general fabrication where a square cross-section is required for ease of fixturing, assembly, or aesthetic preference.<\/p>\n<p>Common tempers for 3003 square bar include <strong>O<\/strong> (\u043f\u043e\u043b\u043d\u043e\u0441\u0442\u044c\u044e \u043e\u0442\u043e\u0436\u0436\u0435\u043d\u043d\u044b\u0439, \u043c\u0430\u043a\u0441\u0438\u043c\u0430\u043b\u044c\u043d\u0430\u044f \u0444\u043e\u0440\u043c\u0443\u0435\u043c\u043e\u0441\u0442\u044c), <strong>H14<\/strong> (half hard, good balance of strength and workability), and <strong>H22<\/strong> (strain-hardened then partially annealed, stable strength with good formability).
