Disclosed are a tungsten material for a penetrating splinter shell and forming method thereof enabling a penetrator to perforate a hard target on high-speed impact as well as having the following splinter cause a severe damage on an inner component by changing a breakage characteristic of the material into brittle fracture from ductile fracture in a manner that a mechanical characteristic of the material is adjusted by controlling a sintering condition and a composition ratio of a tungsten heavy alloy material having Mo added thereto. The present invention includes the steps of mixing 90 SIMILAR 95wt% W powder, 3.0 SIMILAR 8.0wt% Mo powder, 0.5 SIMILAR 3.0wt% Ni powder, and 1.0 SIMILAR 4.0wt% Fe powder with each other, molding the mixed powders, and sintering the molded powders. <IMAGE> |
