Phosphor Bronze: A Buyer Guide

Short answer: Phosphor bronze is a copper-tin alloy with a little phosphorus that combines springiness, low friction, wear resistance and good corrosion resistance, so C510 and C521 serve springs and electrical contacts, C544 serves bearings and bushings and C519 serves connectors and strip, all supplied as certified bar, strip and wire for electrical, marine and precision parts.
