Product Overview
Our Copper Bushings are precision-machined from high-grade copper alloys to provide excellent wear resistance, corrosion resistance, and thermal conductivity. They are widely used as bearing sleeves, guide bushings, and wear parts in machinery, automotive systems, hydraulic equipment, and agricultural tools. Each bushing undergoes strict quality control, and we provide the Mill Test Report with every batch to verify chemical composition and mechanical properties.
