The date of revision is: October 9, 1998. The invention is: 1. The present invention relates to an alloy, especially one. A constituent alloy for a golf club head. [Prior Art] The 5th golf ball is mainly used to drive the club by swinging the swing and using the club head to hit the golf ball. Therefore, the golf club head must have a high frequency hitting ball. In addition to the high strength and high wear resistance that are not worn and damaged, it is necessary to have such characteristics as avoiding the player being too tired and having high stability, so that the golf ball is hit and traveled, and δ a It is even more necessary to take into account the difficulty in the molding preparation process, in order to avoid the problem that the finished product cannot be accepted by the market due to the price factor due to the increase in cost; therefore, the development of new materials, especially different έJ旳,. and alloying, in order to produce a variety of characteristics of the golf j electric burial „ cup head 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋(6A1_4V Ti alloy) rate golf club head suspension helmet is a must for the market and users, because the alloy made of sorghum 4 twist ball 椁 具有 has excellent strength performance, j has The characteristics of wear resistance, 丄, very in line with the average player's shots need another kind of hexa-molybdenum-vanadium-titanium alloy (6AI-IM0-IV Ti alloy), mainly by Mo) '1.Owt% about 6 〇wt% of aluminum (Ai), i.〇wt% of molybdenum (V (V), 2.0wt% of zirconium (Zr), and the patent application of No. 1324938 No. 096108389 Replacement page revision date: 90.0 wt% titanium (Ti) alloy in October 1998 for the manufacture of higher strength, more wear-resistant golf club heads. Although both alloys can be made with high strength With two pairs of wear-resistant golf club heads, it meets the needs of the average player; but if you can further develop alloys of different compositions based on these alloys, the strength of the golf club head can be made. Higher, better wear resistance, and other characteristics such as light weight, stability of hitting, low manufacturing cost, etc., I believe that it can create a double-naked situation between players and industry players. [Invention] The object of the present invention is to provide a The alloy of the golf club head is used to prepare a golf club head with light weight, high strength, high wear resistance and high strike stability. Thus, the alloy of the golf club head of the present invention comprises 7.8Wt. %〜10_0wt% of aluminum, no more than 2% of the content of molybdenum, not more than 2% by weight of vanadium, not more than 2%, and not more than 0, and the balance is used for balance The effect of the invention is that the composition of aluminum and titanium can effectively reduce the specific gravity of the alloy by increasing the content of aluminum, and at the same time, the addition of the cut increases the flow and properties in the alloy molding. Refining the grains by arsenic, indium and titanium to strengthen the structural strength and wear resistance of the alloy, and then producing a light weight, high strength, high wear resistance, high impact stability, and low process cost. The demand for golf club heads. 6 1324938 Patent Application No. 096108389 Supplementary, Corrected, No Line Drawing Instructions Replacement Date: 98 Years of the Year [Embodiment] The foregoing and other technical contents, features and effects of the present invention are described below with reference to the drawings. A detailed description of one preferred embodiment will be apparent. A preferred embodiment of the alloy of the golf club head of the present invention comprises 7.8 wt% to 10.0 wt% of molybdenum which is not greater than and not containing niobium, vanadium of not more than 2 wt% and not containing niobium, and not more than 2 The enthalpy of % is not more than 0, and the rest is titanium which is used for balance and whose content is not bismuth. South strength # characteristics, is that titanium itself has a light weight, high hardness, an excellent deoxidizer 'to a higher weight percentage of 7.8wt% ~ l 〇. 0wt% of the composition of a large amount of titanium, significantly reducing the specific gravity of the alloy, the actual The upper limit of the alloy can be reduced to 4.2 g/em 3 to 43 g/cm 3 , so that the manufactured Nalph club head has a light weight per unit volume, and at the same time, the excessive growth of the alloy crystal grains can be suppressed. The grain is maintained in a small volume state; if it is not larger than the domain and the content is not in the field, the high temperature strength, creep strength and high knives of the alloy can be increased to increase the wear resistance of the manufactured golf club head. The ruthenium which is not more than 2wt% and the content is not 0 can prevent the grain from being too coarse in the grain shape to achieve the effect of refining the grain, and the wear of the golf club head made by the smashing Consumption and strength; :::Add' is based on process considerations, by means of less... H °, 矽 composition makes it easier to improve the fluidity of the alloy in liquid form, and smoothly uses a liquid alloy for golf clubs. Head molding system 7 1324938 No.0961083 The replacement of the No. 89 patent application, the replacement of the manual without the line of the revised page, the revised period: 98 years, 1 month, and then reduced the cost of the process. When the golf club head is made by using the alloy of the present invention, the casting smelting technique is first used, and then the smelting mud is applied to the wax mold to perform the sand blasting operation, and the squeezing and slinging operations are repeated several times, and after air drying, The sand mold can be completed, and the alloy melt of the present invention is poured (filled) into the sand mold, and after the alloy melt is cooled, it is taken out and surface-treated, that is, the golf club head is finished.
