Abstract: This device relates to an intensively improved cable band, especially to a cable band capable of unclipping the clipped band at any time. Tapered type steel ball injection hole (5) is formed to the clip portion (3) by inclinational projection (4) at the end of the band (2) with a predetermined length, and wherein steel ball (6) is inserted inside so that the band (2) is clipped, typical metal cable band (1) configured above makes it possible to easily unclip and reuse the cable band (1) by forming a cut hole (7) longitudinally in the inclinational projection (4) of the clip portion (3) so as to move the steel ball (6).

Abstract: 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˜95 wt % W powder, 3.0˜8.0 wt % Mo powder, 0.5˜3.0 wt % Ni powder, and 1.0˜4.0 wt % Fe powder with each other, molding the mixed powders, and sintering the molded powders.
