Abstract

The compositions comprise about 80 to about 97% by weight of the refractory particles of, for example, tungsten carbide. The particles are bonded within an alloy matrix of between about 5 and about 50% nickel, sufficient carbon to avoid the formation of detrimental carbon deficient or excess carbon phases and a balance of about 95 to about 50% iron by weight. In a preferred embodiment, the alloy matrix additionally contains from about 5 to about 20% by weight of manganese. These compositions are useful for rock drilling.
