Applications requiring high strength and hardness (including temperature) of the occasion. Heavy aircraft, forgings, plate and extrusion materials, wheels and structural elements, multistage rocket first stage fuel tank and spacecraft parts, truck frame and suspension system parts aluminum Al: the remainder of 2014 aluminum alloy silicon Si: 0.6 ~ 1.2 Copper Cu: 3.9 ~ 4.8 Mg Mg: 0.40 ~ 0.8 Zinc Zn: ≤0.30 Manganese Mn: 0.40 ~ 1.0 Titanium Ti: ≤0.15 Ni Ni: ≤0.10 iron Fe: 0.000 ~ 0.700 Note: Individual: ≤0.05; Total: ≤0.15 mechanical properties of tensile strength σb (MPa): ≥440 Elongation δ5 (%): ≥10 Note: vertical bars at room temperature mechanical properties of the sample size: bar diameter (square bar, hexagonal bar inscribed circle diameter) ≤22 Heat Specifications 1) homogenization: Heat 475 ~ 490 ℃; holding 12 ~ 14h; furnace cooling. 2) complete annealing: heating 350 ~ 400 ℃; with the effective thickness of different materials, holding time 30 ~ 120min; with 30 ~ 50 ℃ / h speed with furnace cooling to below 300 ℃, and then cooled. 3) rapid thermal annealing: heating 350 ~ 460 ℃; holding time 30 ~ 120min; air cooling. 4) quenching and aging: hardening 495 ~ 505 ℃, water cooled; natural aging at room temperature for 96h.
