High lead tin bronze bushings, large heavy duty copper bushings, wear-resistant self-lubricating copper bushings, environmentally friendly recyclable copper bushings. This product is based on excellent electrolytic copper, and is mixed with tin ingots and lead ingots according to the national standard ratio to form a high wear-resistant self-lubricating copper alloy material. It exhibits excellent sliding and self-lubricating properties in the absence of lubricants and water-based lubricants. Also under the load of high-speed rotation and rocking motion, the impact load is up to 50MPa, showing excellent flexibility, and it is the first choice for high-speed running machinery and equipment.

Tin bronze is a non-ferrous metal alloy with the smallest casting shrinkage, and is used to produce castings with complex shapes, clear outlines and low air tightness requirements. Tin bronze is very resistant to corrosion in the atmosphere, sea water, fresh water and steam, and is widely used in steam boilers and marine ship parts. Phosphorus-containing tin bronze has good mechanical properties and can be used as wear-resistant parts and elastic parts of high-precision machine tools. Lead-containing tin bronze is often used as wear parts and sliding bearings. Zinc-tin bronze can be used for high air tightness castings.
