Problems solved by technology

[0008] Furthermore, if image 3 As shown, since tungsten is often precipitated on the surface of tungsten-iron-nickel alloy [the dark part is the wavelaid iron structure, and the white part surrounded by the wavelaid iron is the precipitated tungsten], therefore, the "tungsten + The γ[iron, nickel] phase also causes the weight block made of tungsten-iron-nickel alloy to produce patterns after grinding and polishing, so that the weight block made of tungsten-iron-nickel alloy is directly bonded to the bottom surface of the club head body At the same time, the fitting line between the tungsten-iron-nickel alloy and the club head body is clearly visible, and with the difference in grinding thickness and angle, each finished product is different, so it is difficult to control the process conditions

Embodiment Construction

[0029] refer to Figure 4-Figure 6 As shown, most of the manufacturing methods of the counterweight of the golf club head of the present invention are the same as the manufacturing method of the counterweight of the traditional golf club head of Taiwan Patent No. 91116681, so the same parts of the two manufacturing processes and conditions are no longer I will repeat it in detail.

[0030] The counterweight of the golf club head of the present invention is preferably manufactured by precision casting. When performing precision casting, firstly, according to the specific metal melting sequence and composition ratio, the required ingredients are added into the high-temperature furnace at a temperature between 1450-1750°C, preferably between 1600-1680°C, and chromium is added at the same time And properly control the mixing ratio of nickel and tungsten to produce molten tungsten-iron-nickel alloy;

[0031] Then, the molten tungsten-iron-nickel alloy is cast into a preheated mol...

Abstract

A clump weight for head of golf club made from precision cast tungsten iron-nickel alloy, which comprises 15-40% of iron, nickel 30-60%, tungsten15-30%, chromium 1.5-10.0% and molybdenum 0.5-5.0%.

Description

technical field [0001] The invention relates to a counterweight of a golf club head, in particular to a counterweight of a tungsten-iron-nickel alloy that improves cracks caused by welding heat by controlling the mixing ratio of nickel and tungsten and adding molybdenum at the same time. Background technique [0002] The weight of the traditional golf club head is usually made of tungsten [19.30g / cm 3 ], iron [7.8g / cm 3 ] and nickel [8.9g / cm 3 ] The metal powder with high specific gravity and high hardness is press-formed and sintered to form a tungsten-iron-nickel weight suitable for golf club heads. Although the powder metallurgy process is widely used in the industry, there are still many disadvantages in this process, such as: high cost of molding, low elongation of the finished product, long process time, easy thermal expansion and contraction, and inability to form precise patterns, characters, and models and trademarks etc. [0003] Another traditional golf club h...
