    True bronze is copper with 10-12% tin. Most commercial bronzes will
    contain other metals as already said. have a word with you nearest
    sculptors suppliers/art supplier as to where they get their foundry
    work done and go from there. Phosphor bronze is used in machine
    bearings and the like and too hard and often too brittle for
    jewellery working. When bronze casting it is common to add a little P
    bronze to the melt to degas the metal.
