Abstract

PURPOSE: To obtain a superior wire surface without sticking brass on a die obtained by sintering diamond of prescribed grain sizes and volume, carbide, nitride, etc. of IVa group, Va group, VIa group and a prescribed volume of iron group metal.
CONSTITUTION: 20W70vol% diamond having ≤30μm grain sizes, carbide, nitride, boride of IVa group, Va group, VIa group metals and their solid solns. or mixture crystals, and ≤10% iron group metal are mixed. Such mixed powders are sintered in such a way that the diamond particles do not bind to each other, whereby a sintered body having ≤9×104kg/cm2 Young's modulus is obtained. At the time of drawing a brass plated steel wire with the die made of this sintered body, the brass does not stick to the die and the drawn wire of a beautiful wire surface is obtained.
