Suzhou Huijin New Material Technology Co., Ltd. has always adhered to a market-driven R&D philosophy. Leveraging in-depth collaboration with Professor Xiaoqin Zeng's team from Shanghai Jiao Tong University, the company successfully developed a series of heat-treatment-free high-strength and high-toughness aluminum alloy new materials, "Xianjing HA1." On the third anniversary of its launch, this aluminum alloy material, through continuous innovation, has introduced three generations of Xianjing innovative materials and has been successfully applied to large integrated die-casting components for multiple electric vehicle models, including Zeekr, Lynk & Co, and Volvo. Specifically, the first-generation Xianjing has been widely used in large integrated die-casting components such as rear auto bodies, dragonfly brackets, and longitudinal beams + wheel housings. The second-generation high-yield version of Xianjing has increased the yield strength to over 128 MPa at the far end of the body. The third-generation low-carbon environmental protection version of Xianjing has improved Fe content tolerance to 0.35% while allowing the use of over 50% secondary aluminum as raw material.
