Copper-Aluminum Alloys (Aluminum Bronze)

 

The highest strength of any standard copper based alloy.

Aluminum bronze alloys are valued for excellent tensile strength, Brinell hardness and yield strength. Besides exceptional resistance to salt water corrosion, these bronzes are tarnish resistant and exhibit low oxidation rates at high temperature. They feature minimum reactivity with sulphurous compounds and dilute acids, as well as with combustion gases. Non-sparking aluminum bronzes are also biostatic.

CXM is a fully integrated brass and bronze mill – casting, extruding and finishing both standard and exclusive custom alloys. Now a true domestic aluminum bronze supplier, CXM offers engineered solutions for every need, from standard rods and materials to custom alloys and shapes.
