PB104 phosphor bronze alloy bars benefit from superior fatigue & wear resistance. PB104 is a wrought phosphor bronze alloy, a hardened product containing eight percent phosphorus. This alloy provides superior fatigue, wear and corrosion resistance. It is highly suitable for demanding offshore and marine applications. General wear resistance is excellent, as are the alloy's fatigue strength and frictional properties. The addition of tin in the alloying process gives the material excellent wear resistance. Formability & Spring Qualities The cold formability rating of this material is good, with superior resistance to shock loading. The product also provides superb spring qualities combined with high corrosion resistance. In a range of atmospheric conditions, PB104 compares favourably with aluminium bronzes.
