Web6061 (Unified Numbering System (UNS) designation A96061) is a precipitation-hardened aluminium alloy, containing magnesium and silicon as its major alloying elements. Originally called "Alloy 61S", it was developed in 1935. It has good mechanical properties, exhibits good weldability, and is verymonly extruded (second in popularity only to 6063). It is WebAn aluminium alloy (or aluminum alloy; see spelling differences) is an alloy in which aluminium (Al) is the predomit metal. The typical alloying elements are copper, magnesium, manganese, silicon, pal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the WebRelated Topics .
