Abstract
A method of producing an anode material for electrolytic use comprises heat-treating a titanium alloy which consists of 0.1-10 wt % of nickel and the remainder of titanium and unavoidable impurities and which has been thermally affected above its beta transformation point, at a temperature of 400.degree.-800.degree. C. during the process. Alternatively, the alloy is cold-rolled to a working degree of at least 10 percent prior to the heat treatment. The anode material is made to have a surface roughness, Rmax, of at least 100 .mu.m, a yield strength of at least 30 kgf/mm.sup.2, a Vickers hardness of at least 150, and a flatness of at most 6 mm per meter.
