发明名称 ARROWHEAD
摘要 An arrowhead is provided to increase accuracy rate for a target by shortening a length of the arrowhead and concentrating the center of gravity at a front portion of the arrowhead. An arrowhead(100) comprises a body section(10) having a rod shape, and a head section(20) coupled to an end of the body section. The head section has a diameter larger than that of the body section. A tip of the head section is sharpened. The body section and the head section include 94 to 96 weight percent of tungsten, 1.8 to 2.5 weight percent of cobalt, and 2.2 to 3.5 weight percent of nickel. A length of the head section is about 20 to 45% relative to the total length of the arrow head. The total weight of the body section and the head section is 110 to 120 grains.
