ABSTRACT:
An improved shaft suitable for use in the treatment of molten aluminum including pumping or fluxing employing an impeller, comprised of a shaft material comprised of a carbon or graphite having an exterior surface and a refractory layer provided to cover the exterior surface of the shaft. The refractory layer is resistant to attack by the molten metal. The refractory layer and the carbon or graphite material have a coefficient of thermal expansion less than 5.times.10.sup.-6 in/in/.degree. F., the refractory layer has a ratio of coefficient of thermal expansion in the range of 5:1 to 1:5.
