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
The present invention is about a kind of low-density alloy (Low-Density Alloy for Making aGolf Club Head) of golf driver head, particularly about blending ratio by control titanium, aluminium and vanadium, and select to add trace elements such as molybdenum, chromium, iron, silicon and/or boron, for the low-density alloy of the golf driver head of adjusting position of centre of gravity and lifting elastic deformability.
Background technology
The tradition golf driver head is stainless steel mostly, as SUS630 or SUS431 (AISIA AISI standard 630 types and 431 types), and it is made with precision pouring method (dewax method), but the density of this kind material is bigger, and intensity is lower, therefore the bar head made from above-mentioned materials, its wall thickness must reach more than a certain thickness, just can reach the requirement of strength of bar head; Yet, on reality is used,, cause with long-pending can't the increasing of the made rod head body of above-mentioned materials owing to require the bar head key points in design that the nose heave amount of bar must not be too heavy, therefore the preferable striking point on the ball scope on the bar head batting surface can significantly be dwindled, and causes the probability of batting failure to heighten.
For addressing the above problem, the bar head of titanium alloy manufacturing is adopted in the industrial community research and development, as United States Patent (USP) the 5th, 505, No. 795 " golf club manufacture method (Method of manufacturing golf club) ", the 5th, 643, No. 108 " golf club header structure and manufacture method thereof (Structure for golf club head and themethod of its manufacture) ", the 6th, 832, No. 961 " golf driver head of rod (Wood-typegolf club head) ", the 6th, 880, No. 222 " golf club method for making head (Method of manufacturinga golf club head) " and the 6th, 905, the titanium alloy of No. 061 employing Ti-6Al-4V such as " golf club method for making head (Method of makinga golf club head) " (is weight percent 6% aluminium and 4% vanadium, all the other are titanium metal) to make a golf club head, because the density of titanium alloy is lower than stainless steel relatively, and its intensity and stainless steel are suitable, and can present higher relatively elastic deformability, therefore can be under the prerequisite that does not increase the nose heave amount of bar, it allows to strengthen the volume of golf driver head, the preferable striking point on the ball area of golf driver head is increased, to improve shotmaking.
On the other hand, because the density of the titanium alloy of Ti-6Al-4V is lower than stainless steel relatively, therefore it can be used for making the partial component of golf club head, reach the position of centre of gravity of adjusting golf driver head by this, rod head noumenon for example, hitting panel, cover plate or balancing weight etc., and because its elastic deformability (elongation) is relatively higher than stainless steel, therefore utilize its preferable elastic deformability can produce bigger elastic deformation level usually at square stance, and the spheroid compression set that can cause during hitting panel in collision in order to relative minimizing golf ball, reduce the degree of the damped absorption of batting stress relatively, with the power loss of the stress of avoiding batting, and then promote hitting distance.
Yet, considering the long-pending maximization of rod head body and adjusting under the center of gravity nargin, be necessary further to improve above-mentioned titanium alloy, make it more reduce density, and add other element in addition, but still possess former physical strength, to promote the application nargin of titanium alloy.
Other relevant titanium alloy as shown in the following Table I, is enumerated reference in this.
The titanium alloy of table one, traditional various compositions is formed and physical strength
