2A02 Aluminum Alloy


 Mechanical properties:


Tensile strength σb (MPa): 430


Conditions yield strength σ0.2 (MPa): 275


Elongation δ5 (%): 10


Note: The vertical bar at room temperature mechanical properties.


Sample size: bar diameter (square bar, hexagon bar inscribed circle diameter) 150


Heat treatment:


1) Rapid thermal annealing: heating 350 ~ 370 ; with the effective thickness of the material is different, holding time 30 ~ 120min; air or water cooling.


2) Quenching and aging: hardening 495 ~ 505 , water cooling; artificial aging 165 ~ 175 , 10 ~ 16h, air cooling.


Status: aluminum and aluminum alloy extruded bars (150mm, H112.F.T6 state).
