A wear- and corrosion-resistant lining material for extruder barrels or injection molding machine cylinders, constituted of a non-ferrous, tungsten carbide-containing alloy material incorporating from 30 to 45% tungsten carbide, 22 to 61% nickel, up to 37% cobalt, up to 12% chromium, 1.3 to 3.0% boron, 0.7 to 3.3% silicon, and up to 1.0, 3.3 and 0.6% of manganese, iron and carbon, respectively, all percentages being given by weight. The lining is centrifugally cast with the tungsten carbide particles dispersed differentially across a substantial proportion of the thickness thereof.
