Bronze (Copper-Tin and Copper-Aluminium Alloys)

Bronze differs from brass in its better mechanical properties and higher resistance to corrosion.A distinction is made between the listed wrought alloys (up to 8.5% tin content) and the cast alloys (see cast bronze). Not only copper-tin alloys are regarded as bronzes but also copper-aluminium alloys, e.g. CuAl10Ni5Fe4 are referred to as bronzes („Aluminium bronzes“).
