PB104 bronze alloyPB104 Bronze Alloy

PB104 is a high performance wrought phosphor bronze generally used in more demanding applications. Like PB102 it offers superb spring qualities as well as high corrosion resistance that are close to that of aluminium bronzes in a range of atmospheric conditions. Its 8% tin content gives this bronze exceptional wear and bearing properties and offers a good cold formability rating.

Key Features:

PB104 offers excellent wear resistance with good spring properties. The alloy has good cold forming and very high mechanical properties with good resistance to shock loading.
