Aluminium Alloy 2A12 Aluminium Bar
Product Introduction
2A12 aerospace grade aluminum Heat Treatment Specification:
1) Homogenization annealing: heating 480 ~ 495 °C; holding 12 ~ 14h; furnace cooling.
2) Fully annealed: heated 390-430°C; holding time 30-120min; furnace cooled to 300°C, air-cooled.
3) rapid annealing: heating 350 ~ 370 °C; holding time is 30 ~ 120min; air cooling.
4) Quenching and aging [1]: quenching 495 ~ 505 °C, water cooling; artificial aging 185 ~ 195 °C, 6 ~ 12h, air cooling; natural aging: room temperature 96h.
2A12 aerospace grade aluminum is mainly used for making all kinds of high-load parts and components (but not stamping parts forgings) such as aircraft skeleton parts, skins, bulkheads, wing ribs, wing spars, rivets and other working parts below 150 °C.
