2024 aluminum alloy round rod 2024 thin plate
2024 aluminum alloy greatly reduces the content of impurities Fe and Si, and has higher room temperature and high temperature mechanical properties than ZL201. Its cutting and welding properties are good, but its casting properties are poor. It can be used for parts working at 300℃ or parts that bear large dynamic or static loads at normal temperature. Sand casting is often used.
2024 aluminum alloy has relatively good casting performance and high high-temperature strength, hardness and wear resistance, but poor corrosion resistance. It is suitable for casting parts with a working temperature of 250℃ and low load, such as cylinder heads, etc. Mainly used sand casting and metal mold casting.
The 2024 thin plate can be used as the lining plate of machines and refrigerators, automobile air pipes, oil pipes and agricultural irrigation pipes; it can also be processed into thick plates, pipes, bars, special-shaped materials and wires, etc.
This alloy has good formability, corrosion resistance, burnability, fatigue strength and moderate static strength. It is used to manufacture aircraft fuel tanks, oil pipes, as well as sheet metal parts of transportation vehicles and ships, instruments, street lamp brackets and rivets. , hardware products, etc.
2024 aluminum alloy, 2024 is mainly alloyed with copper. It also contains manganese and magnesium and may sometimes contain smaller amounts of silicon, iron, chromium, zinc and/or titanium. It is a high-strength, very hard aluminum alloy. Generally used to manufacture various high-load parts, such as some spare parts on aircraft
2024 aluminum alloy product characteristics
1. A high-strength hard aluminum. Can be strengthened by heat treatment;
2. It has medium plasticity in the annealed and freshly quenched states, good spot welding performance, and a tendency to form intergranular cracks when using gas welding and argon arc welding;
< p>3. The machinability of the alloy is good after quenching and cold work hardening, but the machinability is low after annealing;
4. The corrosion resistance is not high, and anodizing and painting methods are often used or An aluminum layer is added to the surface to improve its corrosion resistance
Uses of 2024 aluminum alloy
It is used to make various high-load parts and components (but not stampings and forgings). Such as aircraft skeleton parts, skin, bulkheads, wing ribs, wing spars, rivets and other parts that operate below 150°C. The trend of replacing 7A04 is useful when making extremely high-load parts
