Features: SPB Cu663 oil sintered Bearing Bronze is considered the standard bearing material for medium duty applications. It also conforms well to journal irregularities and is less dependent on lubrication than other alloys. The alloy has reasonable corrosion resistance to seawater and brine. Cu663 is in higher hardness than SAE841. It is cheaper but with 2-4% Lead Pb. It is used in General Purpose Bushings, Bearings, Insert Bearings, Bushings, Machine Parts, packaging and printing machines, and power tools.
