Large copper bushings have high hardness, excellent wear resistance, not easy to produce bite phenomenon, good casting performance and cutting performance, and good corrosion resistance in the atmosphere and fresh water. It can be used for wear-resistant parts working under high load (below 20Mpa) and high sliding speed (8m/s), such as connecting rods, bushings, shaft tiles, gears, worm wheels, etc.
Large copper bushings are resistant to corrosion, especially to dilute sulfuric acid, hydrochloric acid, and fatty acids. Structural materials, corrosion-resistant, and acid-resistant parts as well as crusher bushings and shingles. Lubricity performance, good wear resistance, and corrosion resistance, suitable for use as the bimetallic casting material. Bearings for vehicles, bimetallic shingles for internal combustion engines with peak loads up to 100Mpa, as well as piston pin bushings, friction plates, etc. In the lack of lubricant and with water lubricant conditions, good sliding and self-lubricating properties, easy cutting, poor casting performance, and good corrosion resistance to dilute sulfuric acid. The bearings with high surface pressure and side pressure can be used to manufacture copper cooling tubes for cold rolling mills, shock load resistant parts up to 50Mpa, bimetallic shingles for internal combustion engines, and piston pin bushings mainly for large loads up to 70Mpa, and acid resistant parts.
