The strength of 7005 seamless aluminum tubing is higher than that of 7003 alloy, which has good welding performance and can be strengthened by heat treatment. 7005 aluminum alloy extruded material is often used to manufacture welded structures that require both high strength and high fracture toughness, such as trusses, rods, and containers of transportation vehicles; large heat exchangers, and cannot be welded after welding. Solid solution treated parts; can also be used to make sports equipment such as tennis rackets and softball bats.
The yield strength of 7075 seamless aluminum tubing is close to the tensile strength, the yield ratio is high, and the specific strength is also high, but the plasticity and high temperature strength are low. It is suitable to be used as load-bearing structural parts at room temperature and below 120℃. The alloy is easy to process. Better corrosion resistance and higher toughness. The alloy is widely used in aviation and aerospace fields, and has become one of the most important structural materials in this field. 7020 seamless aluminum tubing has high strength, good welding performance and process performance. It is the main welding structure material for aerospace vehicles and ground vehicles and equipment. It is widely used in the manufacture of high-speed train bodies and bicycle frames. Support frame for this kind of equipment.
