Alloys consist of small particles of a hard compound embedded in the tough, ductile background of a solid solution. In service, the latter can wear away slightly, leaving the hard compound to carry the load. That wear also provides channels to allow in

White metals are commonly used in bearings and bushings because of their high load-bearing capacity and self-lubricating properties, which reduce friction and extend the lifespan of these components. In the
