Nanshan aluminum successfully developed rare earth aluminum alloy tubes

Recently, Shandong Nanshan Aluminum Co., Ltd. successfully produced 6063a rare earth aluminum alloy pipes, marking a breakthrough in the company's independent trial production of rare earth aluminum alloy pipes. It is reported that 6063a alloy is a new alloy brand developed by Nanshan aluminum company based on the original 6063 alloy and according to the requirements of customers. It has the characteristics of high alloy content requirements, high alloying degree and high extrusion technology. At the same time, it also has the characteristics and difficulties of difficult alloy content control, casting and extrusion crack tendency.

During the development process, the R & D team met the difficulties, and the members performed their respective duties and made careful arrangements. Before the trial production, they made a full demonstration, formulated a detailed trial production plan, and made in-depth analysis and judgment on the technical problems that are prone to occur in production, especially the characteristics of rare earth alloys that have never been touched in production. They formulated the addition and use methods, and continued to track The key technical difficulties in production were solved in time to ensure the orderly trial production. Finally, with everyone's full cooperation, 6063a pipe was successfully extruded.

Rare earth aluminum alloy is to add rare earth elements into aluminum alloy, which can purify the material, improve purity, fill surface defects, refine grains, reduce segregation and eliminate micro unevenness. 6063 aluminum alloy is a commonly used deformation alloy, which is mostly used in industrial and civil buildings. A new type of rare earth aluminum alloy material is formed by adding a small amount of rare earth elements in the melting process of the alloy. Compared with the original alloy material, the tensile strength is increased by 24%, the extrusion speed is increased by 0.5 times, the yield is increased by 3%, and its surface quality is improved, and its corrosion resistance and colorability are increased.
