Product Detail


The 2014 aluminium alloy square bar belongs to both hard and forged aluminium alloys in terms of composition. Compared with 2A50, it has higher strength and better thermal strength because of its higher copper content, but its plasticity is not as good as 2A50 in hot state. 2014 aluminium alloy square bar has good machinability, good contact welding, spot welding and roll welding properties, and poor arc welding and gas welding properties. It can be strengthened by heat treatment and has extrusion effect.
 
2014 aluminium alloy square bar can be used in situations requiring high strength and hardness (including high temperature). Aircraft heavy, forged, thick and extruded materials, wheels and structural components, first stage fuel tank and spacecraft parts of multi-stage rocket, truck frame and suspension system parts.
 
2014 aluminium alloy square bar mechanical property
 
Tensile strength_b (MPa): > 440
Elongation rate (%): > 10
Note: Longitudinal Mechanical Properties of Bars at Room Temperature
 
2014 aluminium alloy square bar heat treatment process
 
1) Homogenization annealing: heating 475-490 C; holding 12-14h; furnace cooling.
 
2) Complete annealing: heating 350-400 C; holding time 30-120 min with different effective thickness of material; cooling with furnace to 300 C at 30-50 C/h speed, then air-cooling.
 
3) Rapid annealing: heating 350-460 C; holding time 30-120 min; air cooling. 4) Quenching and aging: quenching 495-505 C, water cooling; natural aging room temperature 96 h.
