Bronze refers to a broad range of copper alloys, usually with tin as the main additive, but sometimes with other elements such as phosphorus, manganese, aluminium, or silicon.

Brass is the term used for alloys of copper and zinc in a solid solution. The amount of zinc varying from 5 to 45 percent to create a range of brasses each with unique properties[1]. Note that in comparison bronze is principally an alloy of copper and tin.[2]. Despite this distinction, some types of brasses are called bronzes.

Tin is a chemical element in the periodic table that has the symbol Sn (L. Stannum) and atomic number 50. This silvery, malleable poor metal that is not easily oxidized in air and resists corrosion, is found in many alloys and is used to coat other metals to prevent corrosion. Tin is obtained chiefly from the mineral cassiterite, where it occurs as an oxide.
