2A12 Aluminum Rod

Mechanical Properties (Different States, Room Temperature National Standard Reference Values)The properties of this material vary greatly depending on the heat treatment state, with overall strength far exceeding that of 6-series alloys such as 6061 and 6082.

1.O State (Annealed Soft State): Tensile strength 180~220MPa, excellent plasticity, suitable for bending, stamping, and other forming processes, lowest strength.

2.T4 (Solution-Aged Naturally): Tensile strength ≥410MPa, yield strength ≥240MPa, balanced strength and plasticity, good fatigue resistance.

3.T3 (Cold-Worked + Naturally Aged): Tensile strength and strength close to T4, optimal resistance to alternating loads and fatigue resistance.

4.T6 (Solution-Aged Artificial): Tensile strength ≥470MPa, yield strength ≥320MPa, hardness ≥135HB, overall strength reaches peak, strongest rigidity.

5.T651 (Stress-Relieved T6): Strength same as T6, extremely low residual stress, not easily deformed after processing, suitable for precision parts.

6.Comparison Reference: 2A12-T6 has significantly higher strength than 6082-T6, making it the first choice for mid-to-high-end heavy-duty aluminum materials.

Physical Properties:

Density approximately 2.78g/cm³, weight only 1/3 that of steel; moderate thermal and electrical conductivity; melting point approximately 500℃, good dimensional stability at room temperature.
