Beschreibung
Zusammenfassung:	This invention relates to a corrodible downhole article comprising an aluminium alloy, wherein the aluminium alloy comprises (a) 3-15 wt % Mg, (b) 0.01-5 wt % In, (c) 0-0.25 wt % Ga, and (d) at least 60 wt % Al. The invention also relates to a method of making a corrodible downhole article comprising an aluminium alloy, the method comprising the steps of: (a) melting aluminium, Mg, In, optionally Ga, and Ni, to form a molten aluminium alloy comprising 3-15 wt % Mg, 0.01-5 wt % In, 0-0.25 wt % Ga, and at least 60 wt % Al, (b) mixing the resulting molten aluminium alloy, (c) casting the aluminium alloy or producing an aluminium alloy powder, and (d) forming the aluminium alloy into a corrodible downhole article. In addition, the invention relates to a method of hydraulic fracturing comprising the use of the corrodible downhole article.
