A bi-metal copper base material featured by 08 or 10 steel backing and excellent wear resistance. Composition: 70% Cu, 30% Pb. |
Since lead is practically insoluble in copper, a cast copper-lead microstructure consists of lead pockets in a copper matrix. These pockets of lead serve as reservoirs for maintaining a continuous lead film on the bearing surface. With either continuous casting or powder-metallurgy techniques, a steel backing is used with copper-lead bearings for increased strength. These bearings are also frequently used with a babbitt overlay in a three-layer construction. The hardness of copper-lead materials is similar to that of babbitt at room temperature, but is higher at temperatures approaching 300°F. Corrosion of either the lead or copper can be minimized by additives in high-quality automotive and industrial lubricating oils. Copper-lead systems are used for diesel engines on trucks and off-road vehicles, although aluminum alloys are frequently specified for greater corrosion resistance at a sacrifice of compatibility. Copper lead is used in moderate load and speed applications, such as electric motors, turbine engines, and generators. |
