●Aluminum alloy 2014 characteristics and scope of application:

De 2014 aluminum alloy is both a hard aluminum alloy and a wrought aluminum alloy in terms of composition. Compared with 2A50, it contains
The copper content is higher, so the strength is higher, and the thermal strength is better, but the plasticity in the hot state is not as good as 2A50, 2014
Aluminum alloy has good machinability, good contact welding, spot welding and roll welding performance, arc welding and gas welding
Poor energy; warmtebehandeling kan worden versterkt, there is extrusion effect; corrosion resistance is not high, there is inter-test corrosion during artificial aging
tendency. Used in occasions requiring high strength and hardness (inclusief hoge temperatuur). Heavy Forgings, Plates and Extrusions
Materials are used in aircraft structural parts, multi-stage rocket first-stage fuel tanks and spacecraft parts, wielen, vrachtwagenframes
en onderdelen van het ophangsysteem. The corrosion resistance is poor, maar het kan effectief worden beschermd door het te bedekken met puur aluminium; it is easy to produce corrosion during welding
Cracks, but can be welded or riveted using special techniques. Op grote schaal gebruikt in vliegtuigconstructies (skin,
skeleton, rib beam, bulkhead, enz.) klinknagels, raket componenten, vrachtwagen wielen, propeller components and other structures
member.

●2014 aluminum heat treatment specification:

1) Homogenization annealing: heating at 475-490°C; holding for 12-14 hours; furnace cooling.
2) Volledig uitgloeien: heating at 350-400°C; afhankelijk van de effectieve dikte van het materiaal, de houdtijd is 30-120 minuten;
Koel met de oven met een snelheid van 30-50°C/u tot 300°C, en dan luchtgekoeld.
3) Snel uitgloeien: heating at 350-460°C; holding time for 30-120min; luchtafkoeling.
4) Afschrikken en verouderen: quenching at 495-505°C, water cooling; natural aging at room temperature for 96h.
Staat: aluminum and aluminum alloy extruded rods (≤22mm, H112, T6 staat)
