Copper-Based Alloys for Industrial Wear-Resistant Parts

Bronze eccentric bushings are made from high-lead bronze alloys such as ZCuPb10Sn10, ZCuPb15Sn8, and ZCuPb20Sn5. These alloys provide excellent self-lubricating, anti-seizing, and wear-resistant properties, allowing stable performance even under strong impact and heavy dust exposure. The wear resistance can also be enhanced through customized designs to meet the demands of abrasive working conditions.

Bronze nuts and slippers are produced from high-strength copper-based alloys that offer excellent resistance to seawater corrosion. These alloys retain their mechanical integrity and surface stability over time, making them well suited for continuous operation in marine, humid, or chemically active environments.

High-precision bushings are manufactured through centrifugal casting, five-axis CNC machining, and polishing. With strict quality control and CNAS-certified testing, tolerance accuracy reaches ±0.025 mm and surface roughness Ra ≤ 0.8 μm, meeting the standards required for CNC systems.

Yes. Bronze bearings are made following ISO and DIN standards for materials, precision, and surface finish. They can be used with equipment that is manufactured under international requirements, ensuring consistent performance across different applications.

Bronze nuts, sliding bearings and other wear parts can be manufactured according to customer drawings and specifications. Each wear part will be manufactured with micron-level precision to match specific design or size requirements in different industries.
