Phosphor Bronze wound strings were introduced in the early Seventies and have become the most popular acoustic string. Phosphor bronze wire is made from approximately 92% copper, 7% zinc and 1% phosphorous. Phosphor Bronze provides nice highs and lows, as well as pleasant subtle overtones. Phosphorous is used to help reduce tarnish and corrosion.
