AL2024 alloy features and application range:
This is a high-strength hard aluminum that can be strengthened by heat treatment. It has medium plasticity in the quenched and just-quenched state. It has good spot welding. It has a tendency to form intergranular cracks when it is welded by gas. The alloy can be hardened after quenching and cold work. The machinability is good, but the machinability is low after annealing: the corrosion resistance is not high, and anodic oxidation treatment and painting methods are often used to improve its corrosion resistance.
It is mainly used to make various high-load parts and components (but not including stamping forgings), such as skeleton parts, skins, bulkheads, ribs, spars, rivets and other working parts below 150 °C on aircraft.
What is 2024 aluminum sheet ASTM?
ASTM B209 is the standard specification for aluminum and aluminum alloy sheet and plate. The ASTM standard for 2024 aluminum is ASTM B209-12, which is the standard specification for 2024 aluminum aluminum and aluminum alloy sheets and plates.
This ASTM standard covers general requirements for aluminum and aluminum alloy sheet materials. It includes requirements for chemical composition, mechanical properties, heat treatment, dimensional tolerances and other specifications for various aluminum alloys, including 2024.
2024 aluminum sheet
The 2024 aluminum plate is a typical hard aluminum alloy in the aluminum-copper-magnesium system. The 2024 aluminum plate has higher hardness and better overall performance. This alloy is produced in many countries and is the most widely used among duralumin. The characteristics of this alloy are: high strength, certain heat resistance, and can be used as working parts below 150°C.
2024 aluminum plate density
2024 aluminum alloy, density is 2.85 g/cm³.
Heat treatment of 2024 aluminum alloy plate
Aluminum alloy 2024 has good plasticity in the annealed and newly quenched states, and the heat treatment strengthening effect is significant, but the heat treatment process requires strict requirements. Aluminum plate 2024 has poor corrosion resistance and can be effectively protected by pure aluminum covering; it is prone to cracks during welding, but it can be welded or riveted through special technology.
2024 t3 aluminum sheet
2024-T3 aluminum plate is an excellent choice for most processing techniques. 2024 T3 is a high-strength, heat-treatable alloy that offers good corrosion resistance and a high strength-to-weight ratio. 2024 t3 aluminum plate is a lightweight material with a semi-smooth surface and dull finish that is often machined to end-user specifications in a variety of applications, including aircraft, marine, motorsports, gears, computer parts and other commercial grade parts .
