The Introduction Of Performance Characteristics Of Copper Sheath Material
Sep 03, 2018

The copper sleeve shall be lubricated for bearing. It is made of various copper alloys to lubricate the mechanical parts. With all kinds of SOB graphite sleeve large, heavy machinery, it is a mechanical important component.

Performance characteristics of copper sheath material:


1, ZCuSn10Pb1


High hardness, excellent wear resistance, not easy to bite dead phenomenon, Injection molding machine copper sleeve good casting performance and cutting performance, the self-lubricating skateboard in atmosphere and fresh water has good corrosion resistance. Wear-resistant parts can be used for high load (below 20Mpa) and high sliding speed (8m/s), such as connecting rod, bushing, bearing, gear, worm gear, etc.


2, ZCuSn10Pb5

Corrosion resistant, especially for dilute sulfuric acid, hydrochloric acid and fatty acids. Structural materials, corrosion resistant, acid-proof fittings and crusher bushing, bearing bushing.

3, ZCuPb10Sn10

Good lubrication performance, abrasion resistance and corrosion resistance, suitable for double metal casting material. Bearing, load peak of 100Mpa internal combustion engine bimetal bearing, and piston pin sleeve, friction, etc.


4, ZCuPb15Sn8

In the absence of lubricants and water lubricants, the sliding and self-lubricating properties are good, easy to cut, poor casting performance, and good resistance to dilute sulfuric acid. Surface pressure is high, and the lateral pressure of bearing, copper cooling pipe can be made from cold rolling mill, impact resistance load of up to 50 mpa parts, internal combustion engines of bimetallic bearing, mainly used for the biggest load of 70 mpa of piston pin set, acid-proof accessories.

5, ZCuZn38Mn2Pb2

Good mechanical properties and corrosion resistance, good wear resistance and good cutting performance. General use of structural parts, ships, instruments and other simple types of casting, such as sleeve, bushing, bearing, sliding block, etc.
