Adding small amounts of Ti, Zr, Fe or Al and other elements cast bronze, grain refinement, thus forming a porous casting, and impregnated with lubricant oil bearing.
The oil bearing copper alloy is characterized by:
1need for cutting.
2 casting method of production, without forming metal mold, it is appropriate to create a small batch, large-scale oil bearing.
3 bearing and copper-based powder metallurgy oily, copper alloy oil bearings carrying capacity, low wear rate, similar to anti-glue.
Low porosity, less oily, it often requires intermittent oil installations.
