An aluminium extrusion material for use in a hybrid metal extrusion and bonding process is provided. The composition of the extrusion material comprises: 0 to 0.25 wt% iron; at least 0.05 wt% dispersoid-forming elements, wherein the dispersoid-forming elements comprise 0 to 1.2 wt% manganese, 0 to 0.25 wt% chromium, 0 to 0.25 wt% zirconium and 0 to 0.25 wt% scandium; and, except when the aluminium alloy of the aluminium extrusion material is in the 2xxx series, 0 to 0.05 wt% copper. The microstructure of the extrusion material is a deformed microstructure; and the nanostructure of the extrusion material comprises an aluminium matrix with dislocations and dispersoids, and wherein the majority of the alloying elements are in solid solution in the aluminium matrix. An aluminium rod for manufacturing the extrusion material, a joint comprising a extrudate made from the extrusion material a method of manufacturing the extrusion material and the aluminium rod and a method of joining two aluminium components using the extrusion material are also provided. |
