Copper sleeves are made from brass alloys such as H62, H65, etc., and are produced through casting, machining, or extrusion processes. Their core advantages include excellent wear and pressure resistance, good self-lubrication, high mechanical strength, and moderate cost.

Products are mostly seamless in structure, supporting customization of inner and outer diameters and length according to shaft diameter. The surface can be processed with turning and polishing for precision finishing. Widely used in transmission parts of machinery such as machine tools, textile machinery, construction equipment, and automobiles, serving as shaft sleeves and bushes, reducing wear, supporting, and protecting shaft components. They are versatile and cost-effective basic wear-resistant components in the industrial machinery field.
