A method of making an extruded strip less than 1.27 mms thick of lead antimony alloy containing 1 to 2% by weight antimony, the strip having an aspect ratio in excess of 10:1 comprises supplying the alloy at a temperature of 200 DEG C. to 280 DEG C. to an extrusion die and forcing it therethrough so that its temperature as it emerges from the die is in excess of 200 DEG C. and quenching the strip as it emerges from the die whereby its tensile strength within 6 hours of emerging from the die is about 35 Newtons/square mm2. This strip is suitable for conversion to a battery electrode.
