Problems solved by technology

[0002] Traditional golf club heads are mostly made of stainless steel, such as SUS630 or SUS431 (American Iron and Steel Institute AISI standard 630 and 431), and are made by precision casting (waxing method), but this material has a high density and strong strength. Therefore, the wall thickness of the club head made of the above materials must reach a certain thickness in order to meet the strength requirements of the club head; however, in actual use, due to the requirement that the club head weight should not be too heavy The main point is that the volume of the club head made of the above materials cannot be increased, so the range of the best hitting point on the ball hitting surface of the club head will be greatly reduced, resulting in a great increase in the probability of hitting the ball.

Embodiment 1

[0021] As shown in Table 2 and accompanying drawing 1, the low-density alloy of the golf club head of the first embodiment of the present invention is made of titanium metal (density 4.51g / cm 3 ), aluminum metal (density 2.70g / cm 3 ) and vanadium metal (density 5.79g / cm 3 ) as the main alloy composition, titanium aluminum vanadium alloy is composed of 84% to 94% by weight of titanium, 6.5% to 9.5% of aluminum and less than 1.5% of vanadium, with a composition density of 4.40g / cm 3 The following titanium alloys are preferably titanium-aluminum-vanadium alloys with 91% titanium, 8% aluminum and 1% vanadium (such as Ti-8Al-1V alloy or Ti-7.5Al-0.05V alloy shown in Table 2).

Embodiment 2

[0023] In the low-density alloy of another embodiment of the present invention, it is preferable to adjust the weight percentage of aluminum to between 5.5% and 8.5% without changing the original titanium weight percentage of 84% to 94%; in addition, the vanadium The weight percentage is adjusted below 3.0% at the same time. At this time, the low-density alloy still maintains the original mechanical strength of the first embodiment of the present invention.

Embodiment 3

[0025] Compared with the Ti-8Al-1V alloy of the first embodiment of the present invention, the low-density alloy of embodiment 3 slightly reduces the content of aluminum elements, but does not affect the elongation properties of the low-density alloy; at the same time, the low-density alloy slightly Increase the content of vanadium. Compared with the Ti-8Al-1V alloy of the first embodiment of the present invention, the proportion of aluminum and vanadium elements in this low-density alloy is slightly changed. Although the proportion of aluminum and vanadium elements in the low-density alloy is different from that of the Ti-8Al-1V alloy of the present invention, it does not deviate from the technical scope of the low-density alloy of the present invention.

[0026] The following comparative characteristics of the low-density alloy of the present invention and the traditional titanium alloy mainly exemplify the comparison of the Ti-8Al-1V alloy (or Ti-7.5Al-0.05V alloy) and the ...

Abstract

This invention discloses a low-density alloy for head of golf club. The alloy comprises: Ti 84-94 wt.%, Al 6.5-9.5 wt.% (or 5.5-8.5 wt.%), and V less than 1.5 wt.% (or less than 3.0 wt.%). Selectively, trace elements such as Mo, Ge, Fe, Si and / or B can also be added. Since the major component is Ti with a density lower than 4.40 g / cm3, and obtained Ti alloy has a low density and a high elongation rate.

Description

technical field [0001] The present invention relates to a low-density alloy (Low-Density Alloy for Making a Golf Club Head), especially by controlling the mixing ratio of titanium, aluminum and vanadium, and selectively adding molybdenum, chromium, iron, silicon and / or Or boron and other trace elements are used to adjust the position of the center of gravity and improve the low-density alloy of the golf club head with elastic deformation ability. Background technique [0002] Traditional golf club heads are mostly made of stainless steel, such as SUS630 or SUS431 (American Iron and Steel Institute AISI standard 630 and 431), and are made by precision casting (waxing method), but this material has a high density and strong strength. Therefore, the wall thickness of the club head made of the above materials must reach a certain thickness in order to meet the strength requirements of the club head; however, in actual use, due to the requirement that the club head weight should ...
