Shaped aluminum aluminum - copper - magnesium lines typical of hard alloy aluminum square tube manufacturer in Shandong, its composition is more reasonable, better overall performance. Many countries are producing the alloy of aluminum square tube, is the largest amount of hard aluminum. The alloy is characterized by: high strength, heat resistance, Jinan certain aluminum square tube manufacturers, can be used as 150 ° C below the working parts. Temperatures above 125 ° C, the strength of profiled aluminum alloy is higher than 7075. Thermal state, annealing and quenching conditions forming the new performance is better than heat treatment significantly enhanced the effect, but the heat treatment process demanding. Corrosion resistance is poor, but with aluminum coating can be effectively protected; easy to crack when welding, but can be welded using a special process can also be riveting. Widely used in aircraft structures, rivets, card wheel hub, propeller components and various other structures. Standard shaped aluminum sheet for AMS-QQ-A-250/4 (non-CCA); AMS-QQ-A- 250/5 (CCA), shaped aluminum alloy elements of copper, is called duralumin with high strength and good cutting performance, but poor corrosion resistance. Which product aluminum square tube aluminum machining hardened state for improving strength through work hardening, and products after processing after hardening (or not been) reduced the strength of the additional heat treatment. Aluminum code must be followed by two or three roots have Arabic numerals W: an unstable state state solution heat treatment, applies only after solution heat treatment, natural aging of the alloy at room temperature, the state code only indicates that the product is in the nature aging stage T: aluminum heat treatment (unlike F, O, H) suitable heat treatment, after (or without) the work hardening of the product reaches a steady state, T code must be followed by a root or more digits. Aluminum square tube manufacturer | rolls Aluminum (certified) | aluminum square tube is provided by Jinan Heshun Aluminium Limited. Jinan Heshun Aluminum Co.
