High Strength Brass is a type of alloy where aluminum, manganese and iron are added to a copper-zinc alloy. It is high in tensile strength, has toughness and high strength, excellent in terms of inter-heat forgeability, mechanical properties and corrosion resistance, and thus is used for high-class structural materials as well as for components of planes, ships and industrial machines where heavy loads are commonly applied.
