Description of the Invention: [Technical Field] The present invention relates to a weight member of a golf club head, and more particularly to a weight alloy of a golf club head having a preferred extension strength and specific gravity . [Prior Art] A general golf club head is generally composed of a bottom portion, a ball striking surface, a top portion, and a neck portion, and the neck portion is inserted into the shaft to be easily twisted when swung. In order to avoid the torsion generated during the swing, while increasing the smoothness of the swipe and producing a good hitting point, the club head needs to have a lower center of gravity and an appropriate counterweight position. At present, the center of gravity of the club head used in the market is mostly located in the area near the rear half of the club head; the weight method is mostly the production of block, sheet or column weights by powder metallurgy. W (tungsten)-Ni (nickel)-Fe (iron) alloy or W (tungsten)-Ni (nickel)-Cu (copper) alloy is often used. The weight is fixed to the corresponding position at the bottom of the club head by means of embedding, locking, brazing, welding, riveting or gluing. The above-mentioned club head weighting method is fixed at a desired position by a plurality of high-weight weights, and the weight of the club head is adjusted by the distribution of the weights at different positions. However, due to the need to meet both the weight limit of the head and the position of the center of gravity, it is usually necessary to use a computer-aided calculation for the counterweight, and after multiple corrections, the high gravity and low center of gravity of the club head can be achieved. Common ball joints commonly used weights are commonly used in aluminum bronze alloys and tungsten-iron alloys, among which the crane iron alloy (component ratio is about 19.3g/cm3 of crane metal: ferrous metal 7. 8g/cm3: Nickel metal 8·9 g/cm3) has the advantages of weight 200914087 weight, small volume and high hardness, so it is widely used in the industry. Usually, the weight of the 'tungsten-iron-nickel alloy is processed by the powder metallurgy process, which first mixes the metal powder according to the preset ratio and compacts it into 'ασ after' sintering in the south temperature (and vacuum) environment. And processing and heat treatment to obtain a weight. However, the above prior art still has a number of disadvantages, such as high molding cost, low elongation of the finished product, long process time, and inability to directly extrude fine trademarks, patterns, characters, and models. The reason for this is that it is difficult to make a fine trademark pattern because of the extremely high hardness of the crane metal in the crane iron and nickel heavy alloy. If the current machining is performed after sintering, the production efficiency will be affected.岫 岫 岫 以 以 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密 精密Will be in the melt casting process / the problem of the production of crane precipitation 'thus so that the precision is shorter and can directly _ + the purity of this product, the high elongation of the finished product, the process time tungsten-iron nickel counterweight alloy j precision (four) still can not Taking care of the tradition of 'manufacturing.
