Reference standard: AISI
The alloying element in 2014 is copper, known as hard molybdenum, which has high strength and good cutting processability
Pode, but poor corrosion resistance.

●Chemical composition of aluminum alloy 2014:

Alumínio Al: balance
Silício Sim: 0.6~1.2
Cobre Cu: 3.9~4.8
Magnésio Mg: 0.40~0.8
Zinco Zn: ≤0,30
Manganês Mn: 0.40~1,0
Titânio Ti: ≤0,15
Nickel Ni: ≤0,10
Ferro Fe: 0.000~0.700
Observação: single: ≤0,05; total: ≤0,15

●Mechanical properties of aluminum alloy 2014:

Resistência à tração σb (MPa): ≥440
Elongation δ5 (%): ≥10
Observação: Longitudinal mechanical properties of bar at room temperature
Tamanho da amostra: bar diameter (square bar, hexagonal bar inscribed circle diameter) ≤ 22

●Aluminum alloy 2014 characteristics and scope of application:

O 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
A liga de alumínio tem boa usinabilidade, good contact welding, spot welding and roll welding performance, arc welding and gas welding
Poor energy; heat treatment can be strengthened, 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 (including high temperature). Heavy Forgings, Plates and Extrusions
Materials are used in aircraft structural parts, multi-stage rocket first-stage fuel tanks and spacecraft parts, wheels, truck frames
and suspension system parts. The corrosion resistance is poor, mas pode ser efetivamente protegido cobrindo-o com alumínio puro; it is easy to produce corrosion during welding
Cracks, but can be welded or riveted using special techniques. Amplamente utilizado em estruturas de aeronaves (skin,
skeleton, rib beam, bulkhead, etc.) rebites, missile components, rodas de caminhão, 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) Complete annealing: heating at 350-400°C; dependendo da espessura efetiva do material, the holding time is 30-120min;
Cool with the furnace at a speed of 30-50°C/h to 300°C, and then air-cool.
3) Recozimento rápido: heating at 350-460°C; holding time for 30-120min; air cooling.
4) Quenching and aging: quenching at 495-505°C, water cooling; natural aging at room temperature for 96h.
State: aluminum and aluminum alloy extruded rods (≤22mm, H112, Estado T6)
