Problems solved by technology

If the composition of the deplating solution is changed, although the weight block can not be corroded, the nickel-chromium coating on the body cannot be completely dissolved
[0007] The composition of the traditional tungsten-nickel-iron high specific gravity alloy weight block with a specific gravity of 14 is 70% tungsten, 25% nickel, and 5% iron. When deplating the ball head, it is necessary to cover the weight block and do two deplating. The cost is high, and the ball head scrap rate is also high

Abstract

The invention discloses a high-specific-gravity tungsten-nickel-iron alloy for a balancing weight of a golf club and a preparation method thereof, and belongs to the technical field of alloy. The method comprises the following steps: (1) preparing materials, wherein the used metal powder is reduced tungsten powder, hydroxyl nickel powder and hydroxyl iron powder; (2) preparing powder, namely, weighing sieved tungsten powder, iron powder and nickel power with corresponding weight according to the required weight ratio under a clean working environment, wherein the tungsten, nickel and iron in percentage by weight are that 62-80% of W, 7-15% of Ni, and 10-23% of Fe; (3) initially mixing, namely, initially mixing the tungsten powder, nickel powder and iron powder obtained in step (2) through a stainless steel plate, wherein the bottom layer is tungsten powder, the middle layer is nickel powder, and the top layer is iron powder during the initial mixing; and (4) mixing, namely, transferring the initially mixed alloy powder into a mixer to mechanically mix, and then adding an adhesive to obtain the mixed metal powder. According to the high-specific-gravity tungsten-nickel-iron alloy for the balancing weight of the golf club, the ratio of nickel to iron is adjusted, so that the cost can be decreased, and the yield is increased; in addition, the corrosion is avoided, and moreover, the requirement of a ball head can be met.

Description

technical field [0001] The invention relates to a tungsten-nickel-iron alloy and a preparation method thereof, in particular to a high-specificity tungsten-nickel-iron alloy for a golf club counterweight and a preparation method thereof, belonging to the field of alloy technology. Background technique [0002] In recent years, the popularity of golf has become more and more popular, which has also increased the demand for golf clubs and other related products among sports enthusiasts. [0003] In order to make the golf club head play the best hitting effect, it is generally adopted to set a counterweight structure at the bottom of the club head. With the help of this counterweight structure, the center of gravity of the club head moves down, which improves the stability of the golfer's swing. And it can assist the batter to hit the ball effectively, increasing the flying distance of the ball and falling to the expected position. [0004] Chinese patent No. 01317494.8 disclo...
