Introduction to 2A11 Aluminum Plate:
2A11 aluminum plate is the earliest kind of hard aluminum, generally called standard hard aluminum, which is based on the Al-Cu system and incorporates a small amount of elements such as Mg, Mn, and Cr. And it use in quenching and natural aging conditions, when using 2A11 as solder for gas welding and argon arc welding have a tendency to crack; aluminum plate has good stability, corrosion resistance is not high without aluminum, and there is a tendency to cause intergranular corrosion when heated above 100 °C.
Properties of 2A11 Aluminum Plate:
Its surface anodizing and painting reliably protect extruded and forged parts from corrosion. Cutting is good in quenching and aging, and bad in annealing. It also has medium strength, good plasticity in annealing, quenching and hot state, good heat treatment strengthening,
Tensile strength σb (MPa) ) ≥370
Conditional yield strength σ0.2 (MPa) )≥215
Elongation δ5 (%): ≥12
Note: Longitudinal mechanical properties of bars at room temperature
Specimen size: bar diameter (square bar, hexagonal bar inscribed circle diameter) ≤ 150
Use of 2A11 aluminum plate:
1.General mechanical parts or structures such as textile, structural parts of vehicles and other means of transport.
2.Aircraft medium strength components, aircraft propeller blades,
traffic and building components.
3.Ship’s precision instruments.
4.Friction couplings, tools, measuring tools and other components.
Heat Treatment Process of 2A11 Aluminum Plate:
Heat treatment process: Oil quenching and tempering. The strength of this type of steel wire is not as good as that of the lead bath, but the performance is uniform and the cost is low. After the cold roll is formed, the stress relief treatment is performed. Pull out to the specified size and then anneal. After the softened cold roll is formed, it needs to be quenched + moderately tempered to obtain the required mechanical properties.
