C95400 Aluminum Bronze is the most common alloy in the cast aluminum bronze family. Used in many heavy duty applications, it is recommended for high load, high wear applications that require tensile strength, good ductility, weldability or exceptional resistance to fatigue and deformation in overload situations. In addition to good anti-frictional characteristics, the metal also exhibits low rates of scaling in atmospheric conditions, resistance to corrosion in sea water, low oxidation rates at higher temperatures and low reactivity with combustion exhaust byproducts.
