Engineered to meet the exact demands of heavy rotating machinery, agricultural equipment, and clean energy turbines in Paraguay.
Understanding the international shifts in copper alloy production and the technical advantages of Chinese advanced manufacturing.
Globally, lead bronze casting is shifting toward high-precision continuous casting lines. Standard sand-casting methods fail to prevent lead segregation, causing structural inconsistencies and weak load points that result in premature component failure.
Through extensive metallurgical R&D, Sichuan Kepai prevents lead segregation by utilizing continuous casting and electromagnetic induction furnaces. This controls the distribution of lead phases within the copper matrix down to the microscopic level.
By optimizing the raw material supply chain and utilizing highly automated extrusion systems, our Sichuan plant provides high-grade lead copper alloys at scale. This lowers direct material acquisition costs for major infrastructure operators in Paraguay.
Driving quality and environmental responsibility through advanced metallurgy and international standards compliance.
Technological innovation is the core competitiveness of Sichuan Kepai New Materials Co., Ltd. The company has a research and development and production team composed of senior industry experts who keep pace with international cutting-edge technology trends and continuously explore the unknown boundaries in the field of new copper alloy materials.
Through a combination of independent research and development and industry-university-research collaboration, Kepai has made breakthrough progress in several areas, including high-performance tellurium copper, lead copper, and sulfur copper. Many of its technological achievements have reached international advanced levels and have been successfully applied in various industries such as new energy vehicles, precision machining parts, plasma cutting, relays, and energy storage, earning widespread recognition and praise in the market.
