6061 6351 6082 aluminum tube pipe

6061 aluminum tube pipe can be enhanced by heat treatment, with moderate plasticity under annealing, rigid quenching and heat condition, good weldability of spot welding, and the tendency of forming intercrystalline cracks in aluminum tubes when welding and argon arc welding. The cutting properties of aluminum tubes are good after hardening and cold hardening and bad in anneal state. Corrosion resistance is not high. Anodizing and coating methods or surface coating with aluminum coating are often used to improve corrosion resistance.





6082 aluminum tube pipe is a heat-treated reinforced alloy with good formability, weldability, machinability and medium strength. It can still maintain good operation after annealing. It is mainly used in mechanical structure. This alloy has mechanical properties similar to those of the 6061 alloy, but its -T6 state has higher mechanical properties.6082 aluminum tube pipe is a very common alloy product in Europe. It also has high application in the United States. It is suitable for processing raw materials, seamless aluminum tubes, structural profiles and customized profiles. The 6082 aluminum tube pipe usually has good processing properties and good anodic reactivity. The most commonly used anode reaction methods include removing impurities and dyeing, coating and so on. Good processing. It has a very broad application prospect in the field of automobile, architecture and ship.







 

6351 aluminum alloy is one of high strength in 6 series alloy, which is higher than 6061 alloy and slightly lower than that of 6082 alloy. For example, the minimum tensile strength of 6351-T6 profile is 295Mpa, and the extrusion molding is good. 6351 aluminum tube pipe are mostly used for extruding structural materials for highway transportation facilities, and require high gas, oil and water pipelines with high material strength.
