Today, China’s leading high-precision aerospace aluminum alloy sheet, belt and foil manufacturer SDNS Aluminum Alloy Technology Group successfully developed 6005A alloy series profiles for high-speed rail trains. The high-tech content, high added value and excellent performance of this product are all Take the lead in China.
According to reports, 6005A alloy is added to the aluminum substrate with magnesium, silicon, manganese, titanium and other elements, so that the alloy’s strengthening effect is better, with good thermal deformation properties, the quenching temperature range is widened, and online quenching can be achieved ( Air cooling method). This product is currently mainly used in the important parts of the end beam, the end buffer, the base, the threshold, the side member skeleton, the frame bolster of the high-speed rail car body. Nanshan Aluminium Exports Chile’s 160 km articulated EMU aluminum structural material R&D project. All 16 sections use 6005A alloy.
In recent years, China’s rail transit has developed rapidly, and the total mileage of high-speed rail will reach 13,000 kilometers, surpassing Japan and Germany to become a country with a long operating track of global high-speed rail. The aluminum alloy car body used for high-speed rail trains is an inevitable trend for future development, and the aluminum alloy profile market has great potential. However, due to the high technical content of 6005A alloy in rail transit high-speed trains, precise equipment requirements, difficult control, and low product qualification rate, only a few domestic companies can produce it, resulting in a serious lack of ability to produce qualified products of this alloy , Demand mainly depends on imports.
In the context of insufficient domestic supply capacity, SDNS comprehensively considered raw materials, energy consumption, efficiency and other factors, and further optimized the industrialization process, developed a new type of aluminum alloy, which is currently used in the domestic market. Compared with alloy models, the quality has improved significantly, but the cost has not increased significantly.
