The invention is characterised in that there is present in the binder phase a separate tungsten carbide particulattices and the binder phase being distributed in the interstices to form binder pools. The invention is characterised in that there is present in the binder phase a separate tungsten carbide particulate phase in excess of 0.05 total volume %, but not greater than 2 volume %, expressed as a % of the total composite material and that the tungsten carbide particulate phase is homogenously distributede phase in excess of 0.05
