High speed rail is a "big user of aluminum". More than 85% of the car body materials of a high-speed rail are aluminum extrusion materials. The high-speed trains with a speed of more than 200 kilometers per hour have higher requirements for lightweight, sealing and corrosion resistance, while aluminum alloy has the characteristics of light weight, high strength, corrosion resistance and strong plasticity, which makes the aluminum profile car body have absolute advantages in the application of rail vehicles. At present, the vehicles running on the high-speed railway in China are basically aluminum profile cars.
Jinlong aluminum has successfully developed and manufactured aluminum extrusion products for high-speed rail car body from 300km / h, 350km / h to 400km / h, and some products with large cross-section, such as the wide plate at the front of high-speed rail car.
始建于1990年，前期以生產銷售各種有色金屬添加劑，熔劑、鋁中間合金，無煙精煉劑,精煉劑為主，2009年開始和中南大學、中國礦業大學等高校建立戰略合作關系，借助高校的優勢資源聯合研發、制造、銷售鋁基中間產品實現了公司的升級和轉型。
