A method of making material in the form of a fine wire or thin strip or sheet suitable for use as electrical conductors comprises: forming an ingot substantially consisting of an alloy of gold and one or more of the metals titanium, lutetium, zirconium, scandium and hafnium, the amount of the or each of said one or more of the metals in the alloy lying in the range from substantially 0.1 at % to an upper limit comprising the atomic percentage of that metal corresponding to the maximum solubility of that metal in the alloy; solution heat treating the ingot and then quenching the ingot from the solution heat treatment temperature; mechanically working the ingot to have a maximum dimension in at least one direction of not greater than 250 .mu.m; and heat treating the resulting material at a temperature below its solvus temperature from an ambient atmosphere containing oxygen and/or nitrogen in the ambient atmosphere. The conductors exhibit high tensile strength and resistance to elongation under load and retention of such properties after being heated to elevated temperatures for extended periods of time, such as to render them particularly suitable for use as bond-wires in integrated circuit packages.
