Uniformity of polishing of the weight member is thus improved.
Description
- This application is a continuation-in-part application of U.S. patent Ser. No. 10/673,418, filed on Sep. 30, 2003.
- 1. Field of the Invention
- The present invention relates to a weight member for a golf club head. In particular, the present invention relates to a weight member for a golf club head made of WmoNi alloy having a specific gravity ranging between 8.6 and 13.3.
- 2. Description of Related Art
- A conventional weight member for a golf club head is made by powder metallurgy in which metal powders of high density and high rigidity such as tungsten having a density of 19.30 g/cm3, iron having a density of 7.8 g/cm3, and nickel having a density of 8.9 g/cm3 are pressed to form a predetermined shape of the metal powders. Then the shaped metal powders are sintered to form a WFeNi weight member for a golf club head. Although the powder metallurgy is widely used, there exists several disadvantages, including high cost for molds, low stretchability of products, long processing time, aptness to thermal expansion/shrinkage, and difficulty in forming delicate patterns, letters, serial number, trade names, etc.
- Another method for manufacturing a weight member made of WFeNi alloy includes a precision casting process in which a specific metal melting sequence and a specific composition ratio are utilized to prevent sedimentation of tungsten having a high melting point. In the precision casting process, nickel of 30%-50%, iron of 30%-50%, tungsten of 20%-35%, silicon of less than 1%, manganese of less than 1%, and niobium of less than 0.5% are fed into a high-temperature furnace at a temperature above 1450° C. and melted to form a weight member made of WFeNi alloy for use in a golf club head. The weight member is then inserted or welded to a golf club head body that is generally made of stainless steel of SUS304, 17-4, and 4130.
- This precision casting process overcomes the problems of the above conventional powder metallurgy. However, if the mixture ratio of the nickel, iron, and tungsten was not properly controlled, a pearlite structure was precipitated in a base of a γ (iron, nickel) phase of the WFeNi alloy, deteriorating the rust-resisting property of the weight member. Further, such γ (iron, nickel) phase of the WFeNi alloy is apt to result in cracks while welding the weight member to the golf club head body. During spray testing at 40° C. for 24 hours (which simulates a highly corrosive environment) to the WFeNi alloy by using NaCl solution of 5% by weight, the rusted area of the WFeNi alloy often exceeded 8% of the overall surface area of the WFeNi alloy. Further, since tungsten is often precipitated on the surface of the WFeNi alloy (the deep color portion is the pearlite structure and the white portion surrounded by the pearlite structure is the precipitated tungsten), the tungsten/γ (iron, nickel) phase formed by the alloy causes patterns on the weight member made of WFeNi alloy after grinding and polishing procedures. As a result, there exists an obvious insertion line between the WfeNi weight member and the golf club head body when the weight member made of WFeNi alloy is directly inserted into a bottom surface of the golf club head body. Further, the insertion line of the products varies in response to the thickness ground off and the grinding angle. Thus, it is difficult to control the processing conditions.
- In conclusion, since the conventional weight member made of WFeNi alloy contains iron such that the weight member has poor characteristics in the metallographical composition, rust-resisting property, and welding. The assembling procedure, appearance, bonding strength, manufacturing tolerance, and life of the golf club product are adversely affected. There is a need for improving the WfeNi weight member of the golf club head.
- An object of the present invention is to provide a weight member for a golf club head, wherein molybdenum is added to increase the density of the weight member and to improve the rust-resisting property of the weight member. However, molybdenum has a density greater than that of iron, and the rust-resisting property more excellent than that of iron.
- Another object of the present invention is to provide a weight member for a golf club head, wherein the weight member is made of a WMoNi alloy to improve the uniformity of the polishing and the appearance of the weight member.
- To achieve the aforementioned objects, the present invention provides a weight member for a golf club head that is made of a WMoNi alloy by powder metallurgy or a precision casting process. The WMoNi alloy includes tungsten 1-35 wt %, molybdenum 4-55 wt %, and nickel 25-95 wt %, and has a specific gravity ranging between 8.6 and 13.3. Molybdenum increases the density of the weight member and improves the rust-resisting property of the weight member. The tungsten, molybdenum, and nickel provide a uniform metallographic phase. Uniformity of polishing of the weight member is thus improved.
- Further scope of the applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various will become apparent to those skilled in the art from this detailed description.
- The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus are not limitative of the present invention, and wherein:
-
FIG. 1 is an exploded perspective view of a golf club head in accordance with the present invention. - A preferred embodiment of the present invention is now to be described hereinafter in detail.
- Referring initially to
FIG. 1 , a golf club head in accordance with the present invention includes a golfclub head body 20 having arecession 21, and aweight member 10 engaged in therecession 21 of the golfclub head body 20 by means of welding, insertion, pressing, or brazing. The shape of theweight member 10 and the location of therecession 21 can be altered according to the product need. Theweight member 10 can be made by powder metallurgy. - In a case that the weight member is manufactured by a precision casting process, metals are fed into a high-temperature furnace at a temperature between 1450° C. and 1750° C. (preferably 1660° C.-1680° C.) in a specific metal melting sequence and a specific composition ratio while controlling the mixture ratio among tungsten, molybdenum, and nickel, thereby forming a molten WMoNi alloy. Next, the molten WMoNi alloy is poured into a preheated mold with a specific shape, precise patterns, and letters. The preheating temperature for the mold is set between 950° C. and 1300° C. Thus, a weight member for a golf club head is made by a precision casting process. The weight member is then engaged (by, e.g., insertion, welding, pressing, etc.) to a golf club head body that is generally made of stainless steel, such as a series of stainless steel of SUS304, 17-4, and 4130.
- According to the present invention, in the precision casting process, nickel particles, molybdenum particles, and tungsten particles are added in sequence into the high-temperature furnace. The molten nickel reduces the melting point of the tungsten. Thus, the tungsten particles having a high melting point are melted in the furnace without causing sedimentation of tungsten. Next, appropriate sampling test and control are proceeded to form molten WMoNi alloy comprising tungsten 1-35 wt %, molybdenum of 4-55 wt %, and nickel of 25-95 wt % to have a specific gravity ranging between 8.6 and 13.3. Although the density of molybdenum (10.2 g/cm3) is smaller than that of tungsten (19.3 g/cm3), a melting point of molybdenum (2610° C.) is even more smaller that that of tungsten (3410° C.). Accordingly, the furnace temperature required for precision processing can be lowered through increasing the amount of molybdenum and reducing the amount of tungsten. For example, a weight percentage of tungsten is not greater than 35 wt %.
- The density of the WMoNi alloy can be changed according to different uses of the golf clubs. Preferably, the density of the WMoNi alloy is ranging between 8.6 g/cm3 and 13.3 g/cm3.
- In a case that the weight member is manufactured by power metallurgy, tungsten powders of 1-35 wt %, molybdenum powders of 4-55 wt %, and nickel powders of 25-95 wt % are well mixed. Subsequently, the mixed powers are pressed and then sintered to form the required
weight member 10. - In either case, the
weight member 10 made of WMoNi alloy contains no iron, and molybdenum contained in WMoNi alloy has replaced iron contained in the conventional WfeNi alloy. First, molybdenum has a density greater than that of iron. Consequently, the amount of tungsten used in the WMoNi alloy is lower than that used in conventional weight members made of WFeNi alloy. Second, molybdenum has the rust-resisting property more excellent than that of iron. Advantageously, theweight member 10 would not generate pearlite structure that adversely affects the strength or rust-resisting property. Concretely, the weight member in accordance with the present invention has a greater density and improved rust-resisting property. During spray testing at 40° C. for 24 hours (which simulates a highly corrosive environment) to the WMoNi alloy by using NaCl solution of 5% by weight, it will be found that the rusting problem can be significantly improved in the WMoNi alloy. - In addition to insertion, pressing, and brazing, the
weight member 10 can be engaged to the golfclub head body 20 by welding such as tungsten inert gas arc welding, laser welding, or electrical arc welding. - Further, the compositions of tungsten, molybdenum, and nickel contained in WMoNi alloy provide a uniform metallographic phase since no composition of iron exists in WMoNi alloy. There is no γ (iron, nickel) phase to be generated in WMoNi alloy. Thus, precipitation of tungsten on the surface of the WMoNi alloy is prevented, and undesired patterns cannot be generated. Since the surface of the
weight member 10 provides improved polishing uniformity, the insertion line between theweight member 10 and the golfclub head body 20 can be hardly seen when the weight member is directly engaged to (particularly by insertion) the surface of the golfclub head body 20 and then polished. Thus, the engaging difference between individual golfclub head body 20 and theweight member 10 can be avoided, and the processing conditions can be controlled to be the same. Accordingly, the added value and the engaging/assembling tolerance of theweight member 10 are increased. - Further, the flowability during casting can be improved by adding silicon less than 1.5%. Further, an appropriate amount of manganese (Mn), copper (Cu), vanadium (V), and niobium (Nb) can be selectively added. The mechanical properties of the weight member, the flowability during casting, and removal of gas are improved when at least one of Mn of less than 1.0%, Cu of less than 4.0%, V of less than 1.0%, and Nb of less than 1.0% is added. Further, the WFeNi alloy may contain trace elements such as carbon of less than 0.1%, sulfur of less than 0.1%, and phosphorus of less than 0.1%.
- According to the above, the disadvantages of the weight member made by the conventional precision casting process are obviated and/or mitigated by the
weight member 10 in accordance with the present invention. The physical/chemical properties of theweight member 10 are improved by means of replacing iron with molybdenum. The density of theweight member 10 is increased. Further, the rust-resisting property, uniformity of the polishing, appearance, and the assembling tolerance of the weight member are improved while allowing the weight member to be welded to a golf club head body. - While the principles of this invention have been disclosed in connection with its specific embodiment, it should be understood by those skilled in the art that these descriptions are not intended to limit the scope of the invention, and that any modification and variation without departing the spirit of the invention is intended to be covered by the scope of this invention defined only by the appended claims.
