The Al-Cu-Mg system with a high Cu-to-Mg ratio and a minor addition of Ag is the base system of the new high-strength aluminum alloys that are currently receiving major research interest for potential aerospace applications. Since the minor amount of Ag atoms has a significant influence on the microstructure and the mechanical properties,
Al-Cu-Mg-Ag Alloys aluminum extrusion bars is a kind of high strength duralumin, belongs to Al-Cu-Mg aluminum alloy, mainly used for making a variety of high load parts and components, can be strengthened by heat treatment, in the quenching and rigid quenching state of medium plasticity. Al-Cu-Mg-Ag Alloys aluminum extrusion bars has a higher tensile ratio , and is easy for later machining and has a lower deformation rate.
Application of Al-Cu-Mg-Ag Alloys aluminum extrusion bars :
Al-Cu-Mg-Ag Alloys aluminum extrusion bars are used in applications requiring high strength and hardness, including high temperatures. Heavy forgings, plates and extruded materials are used in aircraft structural parts, first-stage rocket fuel tanks and spacecraft parts, wheels, truck frames and suspension system parts.
