An aluminum-based welding filler wire is made with an aluminum alloy that contains between 0.1 and 6 wt. % titanium, including one portion in the form of TiBparticles, TiC particles, or a combination thereof, and another portion in the form of free titanium. The filler wire can be used in welding aluminum-based materials.

Filler wire for welding aluminum alloys

Rolled or extruded products for welded constructions made of AlMgMn type aluminum alloy. These products contain, in % by weight, 3.0&#x3c;Mg&#x3c;5.0, 0.75&#x3c;Mn&#x3c;1.0, Fe&#x3c;0.25, Si&#x3c;0.25, 0.02&#x3c;Zn&#x3c;0.40, optionally one or more of the elements Cr, Cu, Ti, Zr such that Cr&#x3c;0.25, Cu&#x3c;0.20, Ti&#x3c;0.20, Zr&#x3c;0.20, other elements &#x3c;0.05 each and &#x3c;0.15 in total, wherein Mn+2Zn&#x3e;0.75. In the welded state, these products have improved mechanical strength and resistance to fatigue without unfavorable consequences with regard to toughness and corrosion resistance, and are particularly suitable for naval construction, for industrial vehicles and for bicycle frames made of welded tubes.
