Non-leaded bronze is an alloy primarily composed of copper and tin, designed to provide superior corrosion resistance, strength, and machinability without the inclusion of lead. This material is widely used in applications requiring high wear resistance and precision, such as bushings, bearings, and marine hardware. It is favored for its environmental safety, meeting stringent regulations against lead content. Non-leaded bronze offers excellent performance in both dry and lubricated conditions and is often chosen for its ability to maintain structural integrity under high loads and in harsh environments.
