Copper sets of high hardness, excellent wear resistance, not easy to produce galling, better casting performance and cutting performance, good corrosion resistance in the atmosphere and fresh water. For high load (20Mpa less) and high sliding speed (8m / s) working under wear parts, such as connecting rod, bushings, bearings, gears, worm gears.
Copper sets of surface pressure is high, there are side pressure bearing, it can be used to manufacture copper cooling tubes cold rolling mill, impact of negative Heda bimetal bush 50Mpa parts, internal combustion engines, mainly for the largest negative Heda piston pin sets 70Mpa, and Acid accessories. Replacing copper sleeve inner wall 9 oriented band and three grid pen. Before replacing the seal in contact with the inner wall surface of the copper sleeve touch on a little butter to avoid fit is not tight and follow the installation process dislocation. Bevel interface with each guide with superglue bonding firm, 9 oriented interface should be uniform with staggered about 230mm appropriate.
In the absence of lubricants and lubricant use under conditions of water quality, good sliding properties and self-lubricating properties, easy cutting, casting performance is poor, good corrosion resistance to sulfuric acid. It looks simple casting structure general purpose ships, such as the use of instruments, such as sleeves, bushings, bearings, sliders and so on. It is typical of the bronze, hardness and wear resistance are high, can be used to manufacture heavy loads, high speeds and high temperatures, by strong friction parts, such as connecting rod bushings, gears, worm gears.
