Abstract (en)
[origin: WO9532074A2] 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. Furthermore, applications for aluminum alloys containing scandium with or without zirconium additions. Such modified aluminum alloys possess enhanced properties and exhibit improved processing characteristics, and, as such, are especially suited for use in recreational and athletic structures and components, and in certain aerospace, ground transportation and marine structures and components.
