High-performance alloy material for industrial engineering and critical application conditions.
Scope of supply of Aviation Group:
It can be customized non-standard, aluminum plate (whole plate/cut), aluminum rod, aluminum forgings, aluminum tubes, aluminum profiles, etc. Welcome to inquire!
2A14 aluminum alloy is in hard aluminum alloy, and the old grade is LD10. 2A14 has high copper content, high strength, good thermal strength, good machinability, good resistivity, spot welding and seam welding performance, can be heat-treated and strengthened, and has an extrusion effect, but there are differences in longitudinal and transverse properties. The corrosion resistance is not very good, and the intergranular corrosion tendency and stress corrosion and fracture tendency will appear in the artificial aging state.

1) Homogenization annealing: Heating at 475-490℃; insulation for 12-14 hours; furnace cooling.
2) Complete annealing: Heat 350~400℃; depending on the effective thickness of the material, the insulation time is 30~120min; cool with the furnace to 300℃ at a speed of 30~50℃/h, and then air-cool.
3) Rapid annealing: Heating at 350-460℃; insulation time at 30-120min; air-cooling.
4) Quenching and aging: Quenching is 495-505℃, water-cooled; natural aging is 96h room temperature.
