ABSTRACT:
A method for assembling a structure using a filler alloy which includes aluminum and scandium. The method generally includes selecting parts for the structure which are formed from aluminum and/or an aluminum alloy and welding the same together with the aluminum-scandium filler alloy. Similar to the filler alloy, the parts may also include scandium. In one embodiment, the filler alloy and/or the parts further include zirconium. A method for assembling a bicycle frame is also provided. The method includes the steps of forming a first tube, at least a portion of which comprises scandium, forming a second tube, at least a portion of which comprises scandium, and joining the first and second tubes together. A number of aluminum-based alloys are also disclosed which possess enhanced properties. The alloys include scandium in combination with other alloying elements such as, for example, zirconium, copper, magnesium and silicon.
