Abstract WC-6Ni non-magnetic cemented carbide was fabricated mainly from ultra fine WC power and carbonyl
nickel power with a small amount of additives，carbon powder and tungsten powder through sinter-HIP. The influences
of sintering temperature and carbon distribution amount on the density，hardness and bending strength of
WC-6Ni non-magnetic cemented carbide were investigated in the present study. Experimental researches show that
the density，hardness and bending strength of WC-6Ni non-magnetic cemented carbide show different trends with
the increasing sintering temperature. The metallographic porosity rating of the alloy is A02B00C00 with the addition
of 5.98% carbon.
