Abstract

An electrode for resistance welding or heating consists of or is faced with an alloy of about 97 per cent of copper and not more than one per cent of beryllium, together with cobalt. The alloy may consist of 97 per cent of copper, 2,6 per cent of cobalt and 0,5 per cent of beryllium. Such an alloy when heated to 900 DEG C., quenched in water and again heated to 500 to 600 DEG C., for one hour and allowed to cool in air or in a furnace has a conductivity between 36 and 44 per cent that of copper and a Brinell hardness between 170 and 210. This alloy is readily machinable and may be forged, and rolls readily at 850 DEG C., and may also be rolled cold after annealing.
