A nickel-base alloy comprising : 12-40 wt % chromium; up to 13 wt % copper; up to 8% aluminium; balance nickel and incidental impurities is disclosed. Such alloys show an improved carbon corrosion resistance at high temperatures. Such an alloy could therefore be utilised in chemical processing or conveying apparatus, such as steam reforming, syngas production, fertilizer production, ammonia production or coal gasification, or more generally where gases with high carbon potentials are present. The alloy may further comprise one or more rare earth elements, up to a combined total of 1 wt %.
