High strength 6xxx aluminum alloy forging bar technology in Yuefeng Aluminum Material Institute has been popularized and applied

May 24, 2023
Recently, the high strength 6xxx aluminum alloy high quality ingot preparation integrated technology developed by Yuefeng Aluminum Materials Institute has effectively broken through the bottleneck of relying on imported casting equipment for high-end bar materials, and achieved the iterative upgrade of aluminum alloy bar products after being promoted and applied in member enterprises of Yuefeng Aluminum Group.
 
Under the background of green and low-carbon environmental protection, aluminum wheel has become a hot spot for commercial vehicle manufacturers to compete for its light weight, low inertia resistance, light weight and fuel saving. The melting and casting team of Yuefeng Aluminum Materials Institute grasps this market tuypoint, constantly optimizes the technical process, effectively solves the common technical problems of the mutual constraints of the strength, elongation and fatigue properties of the traditional 6xxx aluminum alloy, develops a set of high-quality ingot preparation integration technology, and realizes the comprehensive performance of bar products has been significantly improved.
 
The high strength 6xxx aluminum alloy casting rod produced by this technology is used to prepare high strength and ultra-light forged wheel hub for commercial vehicles of a certain specification. The comprehensive performance of forged wheels is far superior to that of existing forged wheels in the United States and China, and the tensile strength of forged wheels of the same specifications is increased by 10% and the weight is reduced by 7%, and the tensile strength of forged wheels of the same specifications is increased by 17% and the weight is reduced by 14%. The dynamic fatigue performance of the wheel is much better than the strict test standards of the European Union. At the same time, due to the weight reduction factor, hub enterprises using the technology of high strength rod material production hub cost can be effectively reduced.
 
After the application of this technology, the quality of high-strength 6xxx bars produced by Wuxi Yuefeng Aluminum Technology has been greatly improved. In the case of twice the output, the product is still in short supply, and passed the product quality audit of Alcoa wheel enterprise, and successfully entered into the industrial chain of Alcoa forged wheel. Through the application of this technology, Shanxi New Material has realized the transformation and upgrading of domestic oil-gas sliding equipment and realized the substitution of imports. The high-strength 6xxx aluminum alloy forged bar prepared by this equipment has reached the same level as the bar produced by imported equipment, and successfully entered the domestic forged wheel hub bar market, helping enterprises to open up new market areas.
