Aluminium bronzes' resistance to corrosion results from the aluminium in the alloys, which reacts with atmospheric oxygen to form a thin, tough surface layer of alumina (aluminium oxide) which acts as a barrier to corrosion of the copper-rich alloy. ... Aluminium bronzes tend to have a golden color.
Aluminum bronzes are used in marine hardware, shafts and pump and valve components for handling seawater, sour mine waters, nonoxidizing acids, and industrial process fluids. They are also used in applications such as heavy duty sleeve bearings, and machine tool ways.
Properties and Purposes: Aluminum Bronze. Aluminum bronze is a class of alloys that are generally composed of copper, between nine and 12% aluminum, and at most 6% iron and nickel.
Aluminum corrodes but it does not rust. Rust refers only to iron and steel corrosion. Aluminum is actually very prone to corrosion. However, aluminum corrosion is aluminum oxide, a very hard material that actually protects the aluminum from further corrosion.
It is 62 ksi or 430 MPa of alloy containing 80% Copper, 4% Iron, 4.3% Nickel and 11% Aluminum.
Aluminum bronze is a class of alloys that are generally composed of copper, between nine and 12% aluminum, and at most 6% iron and nickel. ... Has a higher tensile strength than other bronze alloys. Tarnish resistant and have low oxidation, even at high temperatures. These are non-magnetic and non-sparking.
