We designate bronze to the copper and tin alloys with contents of Sn of the 2 to the 25%. Frequently these alloys contain other elements as the lead or the zinc, something which permits to split them in binary bronze and complex bronze those which have three or more elements. Copper and aluminium alloys frequently designated bronze to the aluminium are described apart low the denomination of Copper-Aluminiums.

The binary bronze are known also as phosphorous bronze because of the residual phosphorus content that is appended for desoxidize the alloy. The complex bronze with zinc are designated usually red bronze.
