PB103
PB103 phosphor bronze containing 6% tin, available primarily in sheet and strip. The tin content, which is higher than in PB102, gives the alloy improved wear resistance and higher strength properties. PB103 is also renowned for its excellent tarnish resistance and corrosion resistance to a wide range of waters and chemicals in environments such as paper and textile manufacturing plants.
