- Generally speaking, in order to meet the user's lightweight requirement of the golf club head, a person ordinarily skilled in the art may manufacture the golf club head with a titanium alloy. For example, the conventional titanium alloy includes aluminum, vanadium, chromium, silicon, iron, titanium and inevitable impurities. However, due to the poor fluidity of the conventional titanium alloy, the formation rate of the golf club head under a vacuum centrifugal casting method for manufacturing the golf club head is merely 40-60%. Thus, it is necessary to provide a titanium alloy for casting a golf club head to solve the problems mentioned above.
- To solve the problems mentioned above, the purpose of the present invention is to provide a titanium alloy for casting a golf club head at an excellent formation rate of the golf club head.

As such, by the mix portion of the composition of aluminum, vanadium, chromium, silicon, iron and titanium, the titanium alloy for casting a golf club head of the present invention with the vacuum centrifugal casting method may provide good formation rate, and the golf club head of the present invention may also have better mechanical properties, such as tensile strength and yield strength, than the golf club head manufactured by the conventional titanium alloy, which are the effects of the present invention.
- The titanium alloy for casting a golf club head of the present invention, wherein the titanium alloy comprises 7.25-7.75 wt % of aluminum. As such, the fluidity of the titanium alloy for casting a golf club head may be increased by adjusting the aluminum content.
- The titanium alloy for casting a golf club head of the present invention, wherein the titanium alloy comprises 4.25-4.75 wt % of vanadium. As such, the strength of the titanium alloy for casting a golf club head may be increased by adjusting the vanadium content.
- The titanium alloy for casting a golf club head of the present invention, wherein the titanium alloy comprises 1.0-1.5 wt % of chromium. As such, the strength of the titanium alloy for casting a golf club head may be increased by adjusting the vanadium content.
- The titanium alloy for casting a golf club head of the present invention, wherein the titanium alloy comprises 0.05-0.10 wt % of silicon.
- The titanium alloy for casting a golf club head of the present invention, wherein the titanium alloy comprises 0.05-0.08 wt % of iron. As such, the strength of the titanium alloy for casting a golf club head may be increased by adjusting the iron content. As such, the strength of the titanium alloy for casting a golf club head may be increased by adjusting the iron content.
- The titanium alloy for casting a golf club head of the present invention, wherein a tensile strength of the golf club head is between 140 ksi and 150 ksi, wherein a yield strength of the golf club head is between 128 ksi and 138 ksi, and wherein an elongation rate of the golf club head is between 4% and 8%. As such, the strength of the golf club head may meet the requirement for swinging, allowing the useful life of the golf club head to be increased.
- The titanium alloy for casting a golf club head of the present invention, wherein a formation rate of the golf club head is between 85% and 96%. As such, the strength of the golf club head may meet the requirement of swinging, allowing the waste produced in the process of casting the golf club head to be decreased.
- To make the aforementioned and other objectives, characteristics and advantages of the invention obvious and to facilitate the understanding of said objectives, characteristics and advantages, the preferred embodiments of the invention are elaborated below with the accompanying drawing.
- The titanium alloy for casting a golf club head may comprise specific ratios of aluminum (Al), vanadium (V), chromium (Cr), silicon (Si), iron (Fe), with the remaining being titanium and inevitable impurities.
- Specifically, the titanium alloy for casting a golf club head may comprise 7.0-8.0 wt % of aluminum, and preferably comprise 7.25-7.75 wt % of aluminum. As such, the fluidity of the titanium alloy for casting a golf club head may be increased. It should be noted that the golf club head will become brittle when the golf club head contains an excessive amount of aluminum. Thus, the aluminum content of the golf club head should not exceed 8.0%.
- The titanium alloy for casting a golf club head may comprise 4.0-5.5 wt % of vanadium, and preferably comprise 4.25-4.75 wt % of vanadium. As such, the mechanical properties (such as tensile strength and yield strength) of the titanium alloy for casting a golf club head may be increased. However, it should be noted that the formation rate of the golf club head will be affected when the golf club head contains an excessive amount of vanadium. Thus, the vanadium content of the golf club head should not exceed 5.5%.
- The titanium alloy for casting a golf club head may comprise 0.5-1.5 wt % of chromium, and preferably comprise 1.0-1.5 wt % of chromium. As such, the mechanical properties (such as tensile strength and yield strength) of the titanium alloy for casting a golf club head may be increased. However, it should be noted that the formation rate of the golf club head will be affected when the golf club head contains an excessive amount of chromium content. Thus, the chromium content of the golf club head should not be exceed 1.5%.
- The titanium alloy for casting a golf club head may comprise 0.05-0.15 wt % of silicon, and preferably comprise 0.05-0.10 wt % of silicon. However, it should be noted that the elongation rate and formation rate of the golf club head will be decreased when the golf club head contains an excessive amount of silicon content. Thus, the silicon content of the golf club head should not be exceed 0.10%.
- The titanium alloy for casting a golf club head may comprise 0.05-0.3 wt % of iron, and preferably comprise 0.05-0.08 wt % of iron. As such, the mechanical properties (such as tensile strength and yield strength) of the titanium alloy for casting a golf club head may be increased. However, it should be noted that the formation rate of the golf club head will be affected when the golf club head contains an excessive amount of iron content. Thus, the iron content of the golf club head should not be exceed 0.3%.
- Thus, the formation rate of the golf club head is increased as a person ordinarily skilled in the art manufactures the golf club head using the titanium alloy for casting the golf club head mentioned above with a vacuum casting method. The tensile strength and the yield strength of the golf club head cast by the titanium alloy are better than the golf club head cast by the conventional titanium alloy.
- To verify the formation rate of the golf club head as being improved and better mechanical properties of the golf club head are obtained through the use of the titanium alloy for casting the golf club head mentioned above with a vacuum casting method, the following embodiments have been conducted.
- The formation rate of the golf club head manufactured by the titanium alloy of the present invention (A1 group) can reach 85-96%, whereas, the formation rate of the golf club head manufactured by the conventional titanium alloy (A2 group) was merely between 40% and 60%.
- Moreover, the mechanical properties of the golf club head mentioned above were shown in Table 1.
-
TABLE 1 Mechanical properties of each group of the golf club head in the test: Tensile Strength Yield Strength Elongation Rate Group (ksi) (ksi) (%) A1 140-150 128-138 4-8 A2 128-138 115-125 3-7 - As shown in Table 1, the tensile strength and the yield strength of the golf club head manufactured by the titanium alloy of the present invention are significantly higher than those of the golf club head manufactured by the conventional titanium alloy. It shows that the composition ratios of the aluminum, vanadium, chromium, silicon, iron and titanium contained in the titanium alloy for casting the golf club head may increase not only the formation rate of the golf club head but also the mechanical properties (such as tensile strength and yield strength).
- In summary, the golf club head manufactured using the titanium alloy for casting the golf club head mentioned above with the vacuum centrifugal casting method may have an excellent formation rate, and the golf club head manufactured by the present invention may also have better mechanical properties (such as tensile strength and the yield strength) than the conventional titanium alloy, which are the advantages of the present invention.
- Although the invention has been described in detail with reference to its presently preferable embodiments, it will be understood by one of ordinary skill in the art that various modifications can be made without departing from the spirit and the scope of the invention, as set forth in the appended claims
