<p><span style="color: rgb(136, 136, 136);">Mg Alloy, with good plasticity and corrosion resistance, especially no stress corrosion cracking tendency, has excellent weldability and strong processability, and is a commonly used alloy aluminum plate. The main alloy of 6061 aluminum alloy is magnesium and silicon, and Mg2si is formed. If it contains a certain amount of manganese and chromium, it can neutralize the bad effects of titanium and iron; Sometimes a small amount of copper or zinc can be added to improve the rigidity of the alloy without significantly reducing the corrosion resistance, A small amount of copper in the conductive material can offset the adverse effects of titanium and iron on the conductive material. Lead can also be added to improve the machinability. Because it contains magnesium Silicon element, 6061 alloy has medium strength, good corrosion resistance, weldability and good oxidation effect. 6061 aluminum alloy plate has excellent processing performance, good corrosion resistance, high toughness, difficult deformation after processing, easy color molding and excellent oxidation effect. </span></p><p><br></p><p><span style="color: rgb(136, 136, 136);">The difference between </span><a href="https://www.canyimetal.net/6-series-aluminum-material" rel="noopener noreferrer" target="_blank" style="color: rgb(136, 136, 136);">6061 aluminum plate</a><span style="color: rgb(136, 136, 136);"> state T6 and T651 is that the internal stress of T6 is relatively large under normal circumstances, and the processing will be deformed. The State suitable for processing should be T651, which is stretched on the basis of T6, eliminate internal stress. T651 is the main alloy of 6061 aluminum plate. It is a high-quality alloy aluminum plate product produced by heat treatment and pre-stretching process. It has many characteristics of magnesium and silicon alloy, it has excellent processability, excellent welding characteristics, electroplating, good corrosion resistance, high toughness, no deformation after processing, dense and defect-free materials, easy polishing, easy coloring film, excellent oxidation effect, etc. excellent characteristics. 6061 T6 high strength, high hardness (Up to HB95 degrees or more)Good processing effect and good oxidation effect. No trachoma pores, good flatness. Improve processing efficiency and reduce material cost. This will be the best choice for low price and high quality materials. The main difference between the two: the difference between T6 and T651 is that under normal circumstances, the internal stress of T6 will be relatively large, and the processing will be deformed. The most suitable state for processing should be T651, he stretched on the basis of T6 to eliminate internal stress, 6061- T6 state: cooling after Solution heat treatment to achieve high strength, no cold working, 6061- T651 state: cooling after Solution heat treatment to achieve high strength, and then cold stretching through a stretching machine to eliminate residual internal stress after heat treatment and to ensure precision of machined products without deformation after deep processing. 6061- T6511 state: cooling after Solution heat treatment to achieve high strength, and then correcting and straightening process. </span></p><p><br></p><p><span style="color: rgb(136, 136, 136);"><span class="ql-cursor"></span>Their usage is as follows: Under normal circumstances, if there is no precise requirement for dimensional stability and elastic margin, T6 state is selected; If the precision workpiece, in order to avoid the elastic recovery after processing and the size can not be stable, it is necessary to use T651. The specific explanation is as follows: after the workpiece is processed by lathes, milling machines, etc. , because the workpiece is affected by multiple forces during processing, and the workpiece has certain elasticity, it does not change under the action of external force, however, the external force is removed after processing. At this time, only the internal stress exists, and the internal stress will drive the elastic recovery of the workpiece, so the size will inevitably change.</span></p>
