Problems solved by technology

Furthermore, since the surface of the tungsten-iron-nickel alloy often has tungsten precipitated (the dark part is the wavelaid iron structure, and the white part surrounded by the wavelaid iron is the precipitated tungsten), so the "tungsten + The γ (iron, nickel)" phase also causes the weight block made of tungsten-iron-nickel alloy to produce patterns after grinding, so that the weight block made of tungsten-iron-nickel alloy is directly bonded to the bottom surface of the club head. At the same time, the fitting line between the tungsten-iron-nickel alloy and the club head 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
[0005] As mentioned above, since the weights of the conventional tungsten-iron-nickel alloys all contain iron components, the weights are prone to defects in metallographic composition, rust and corrosion resistance, and welding properties, and seriously affect golf club heads. The assembly, appearance, bonding strength, process margin and service life of the finished product, so it is indeed necessary to further improve the tungsten-iron-nickel alloy weight of the conventional golf club head

Embodiment Construction

[0014] Please refer to figure 1 As shown, it discloses an exploded perspective view of the weight block of the golf club head of the present invention. one

[0015] The counterweight 10 can be combined in a chamber 21 of a rod head 20 by means of welding, embedding, pressing and brazing. The shape of the counterweight 10 and the position of the chamber 21 are selected and changed according to product requirements, and the present invention can choose to manufacture the counterweight 10 by precision casting or powder metallurgy.

[0016] When choosing to use the precision casting method, firstly, the required ingredients are added to the high-temperature furnace (the temperature is between 1450°C and 1750°C, preferably between 1660°C and 1680°C) according to the specific metal melting sequence and composition ratio. At the same time, the mixing ratio of tungsten, molybdenum and nickel is properly controlled to obtain molten tungsten-molybdenum-nickel alloy; then, the molten t...

Abstract

Disclosed is a clump weight of golf ball rod head made of powdered metallurgy or precision cast wolfram molybdenum nickel alloy, wherein the wolfram molybdenum nickel alloy compromises (by weight ratio) wolfram 1%-70%, molybdenum 4%-55% and nickel 25%-95%.

Description

technical field [0001] The invention relates to a counterweight of a golf club head, in particular to a counterweight whose specific gravity, antirust and corrosion resistance and uniformity of bright surface are improved by molybdenum. Background technique [0002] The counterweight of conventional golf club heads is usually made of tungsten (19.30g / cm 3 ), Iron (7.8g / cm 3 ) and nickel (8.9g / cm 3 ) of metal powder with high specific gravity and high hardness, which is press-formed and sintered to form a tungsten-iron-nickel weight suitable for golf club heads. Although this 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 finished products, long process time, easy thermal expansion and contraction, and inability to form precise patterns, characters, Model and trademark etc. [0003] Another commonly used counterweight for golf club heads, such as "a counterweigh...
