Claim 6:
7. A cermet material, comprising:
tungsten carbide particulates; and
an alloy binder placed within the tungsten carbide particulates, the alloy binder comprising a transition metal included in a Ni Cr Al alloy that causes no liquid phase below 1310° C., creates over 45% of a gamma phase above 900° C. up to 1310° C., and creates over 30% comprised of a gamma prime phase between 450° C. and 600° C., wherein the gamma prime phase is characterized by a formula (Ni,Co)x(Cr,Al,Mo)y wherein x and y are integers, wherein an amount of the Al in the alloy binder is 3.1 to 5.1 weight percent, wherein the transition metal comprises at least one of Co, Mo, and W, wherein a weight percent of the alloy binder in the cermet material is 40%, and wherein a weight ratio of the tungsten carbide particulates to the alloy binder is 1.5 or less.
