Xuzhou Promise Import & Export Co., Ltd specializes in the research and development of innovative composite materials and advanced thermal management solutions. We are committed to providing high performance materials and key technical support for industries such as marine and offshore engineering, high-end manufacturing, electronics and power, rail transportation, aerospace, telecommunications, intelligent computing centers, semiconductor manufacturing, medical devices, and equipment. The company focuses on three core product lines "Dissimilar Metal Composite Materials", "Advanced Welding Materials" and "Full-Spectrum Thermal Solutions" to help customers enhance the competitiveness of their high-end products.

Breaking the performance limits of traditional materials, our proprietary friction stir welding (FSW) composite technology enables high-strength bonding between dissimilar metals (e. g., Al/Steel, Al/Copper, Fe/Al, Ti/Al). These materials combine high strength, corrosion resistance, and long service life, making them ideal for ship structural components, automotive bodies, cryogenic containers, offshore engineering equipment, smelting electrodes, and new energy battery connectors. They address industry demands for light weighting and high reliability.
