Aircraft materials 2014 T3 T4 aviation aluminum sheet
- Jul 19, 2018 -

The main element of the 2014 aluminum sheet is copper, with high strength and good cutting performance, but its corrosion resistance is poor. It is widely used in aircraft structure (skin, skeleton, rib beam, frame, etc.) rivet, missile component, truck hub, propeller element and a variety of other structural parts. 


Heat treatment 

1) Homogenization annealing: heating 475 ~ 490 ° C; holding 12 ~ 14h; furnace cooling.

2) Complete annealing: heating 350-400 ° C; with the effective thickness of the material, the holding time is 30-120 min; at 30-50 ° C / h, the furnace is cooled to 300 ° C, and then air-cooled. 

3) Rapid annealing: heating 350 ~ 460 ° C; holding time 30 ~ 120min; air cooling. 

4) Quenching and aging: quenching 495 ~ 505 ° C, water-cooled; natural aging room temperature 96h.
