INSTRUCTIONS: [Technical Field] The present invention relates to an α-titanium alloy material applied to a golf club head, in particular, to a ratio of the weight percentage of titanium, Ming and tin. The golf club head alloy material having high elongation is added by adding trace elements such as bismuth, hunger, bismuth, zirconium, complex, iron, broken, oxygen and/or nitrogen. [Prior Art] The alloy technology currently developed for use in golf club heads is mainly titanium strontium alloy material, as disclosed in US Patent No. 2006/0045789, the conventional 6A1-4V-Ti titanium alloy (ie, weight percentage for Ming and hunger) The balance is titanium metal), the composition of which comprises 5.5 to 6.75 weight percent, 3.5 to 4.5 weight percent of hunger, maximum of 0.3 weight percent of iron, and a maximum of 0.2 weight percent of oxygen. The golf club head made of 6A1-4V-Ti titanium alloy has the characteristics of higher elastic deformation force, the same strength and lower density than the club head made of stainless steel in the early stage. The volume of the golf club head is increased without increasing the weight of the golf club head so that the area of the preferred hitting point is relatively increased, so as to have a high hitting success rate. In addition, the elastic deformation force higher than that of the stainless steel can provide a large elastic deformation ability when hitting the ball, and can also generate a large degree of elastic deformation-elongation, and can relatively reduce the golf ball when hitting the impact panel. The resulting ball is compressed and deformed to reduce the degree of damping of the ball striking stress, avoid the energy loss of the ball striking stress, and further increase the hitting distance. 5 200932921 However, until now, under the demand for large and diverse golf club heads, there is a need to develop low density and high ductility, but still maintain the original mechanical strength to improve design margin. SUMMARY OF THE INVENTION In view of the above needs, the problem to be solved by the present invention is to provide a high plasticity, high elongation titanium aluminum tin alloy for adjusting the elastic deformation ability of a golf club head. Another problem to be solved by the present invention is to provide a titanium I-alloy with a high elongation and to fine-tune the titanium-aluminum-tin alloy by using a small amount of the modifier element. In order to solve the above problems, the technical means proposed by the present invention is to provide a titanium aluminum tin alloy, the weight percentage thereof comprising: 89 to 95% of titanium, 3.5 to 6.5% of aluminum, and 1.5% to 3.5% of tin. The titanium aluminum tin alloy of the present invention described above has a density in the range of 4.25 to 4.45 g/cm3. The above titanium aluminum-tin alloy of the present invention is formed by casting, forging or mechanical processing with a titanium alloy having an elongation of 11% to 15% and a tensile strength of 700 to 950 MPa. 5%至3. 5%, 5% to 3. 5%, 5% to 5%, 5% to 5%, 5% to 5%, 5% to 5%铌S 2%, vanadium S 2%, molybdenum S 2%, zirconium S 2%, chromium $2%, iron $1%, 矽$1%, oxygen^0.3%, and nitrogen^0.05%. The above titanium tin-tin alloy of the present invention has a composition density ranging from 4.25 to 4.45 g/cm3. 6 200932921 The content of titanium and aluminum in the titanium-aluminum-tin alloy of the present invention has a significant effect on improving the normal temperature and high-temperature strength of the alloy, lowering the specific gravity, and increasing the elastic modulus compared with the conventional 6A1 - 4V Ti; Hunger, turn, bismuth, chromium, and iron are yS stabilizing elements. Compared with 6Ai-4V_Ti, the amount of vanadium added is greatly reduced, thereby reducing the manufacturing cost of titanium aluminum tin alloy. Further, the invention has good hot workability, is easy to mass-produce in a factory, and has a lower density than the same alloy, which is advantageous for the enlargement of the golf club head and the design margin thereof. [Embodiment] A preferred embodiment of the present invention will be described below in conjunction with the drawings. Referring to FIG. 1, FIG. 2 and FIG. 3, the titanium alloy of the first embodiment of the present invention has a weight percentage of the alloying elements of the alloy: 89% to 95% of titanium, and 3.5% to 5% of aluminum. And tin alloys with a density ranging from 4.25 to 4.45 g/cm3, an elongation of 11% to 15%, and a tensile strength of 700 to 950 MPa, and casting, forging or Machining into a ❹ type. The invention can also adjust its characteristics by adding a trace amount of a modified element, such as a group consisting of elements such as lanthanum, vanadium, niobium, chromium, molybdenum, iron, lanthanum, oxygen and nitrogen, for example, The strength of the alloy is increased by adding a small amount of 鉱', but the elongation property is not reduced; the fluidity during casting and the auxiliary degassing effect can be improved by relatively reducing the amount of slave addition, but the original alloy is not affected. Mechanical properties; by adding a small amount of molybdenum, the alloy can precipitate a uniformly distributed carbide and improve the heat resistance, so as to reduce the alloy welding 200932921 thermal cracking phenomenon can also increase the hardening ability and high temperature strength of the alloy; A small amount of zirconium makes the alloy after molding improve the strength of the material without being deformed by heat treatment, and can be combined with the addition of molybdenum to form high strength and high toughness (the raw ' "I by adding an appropriate amount of chromium' to enhance the alloy Anti-rust and button resistance, the service life of the rain-fighting club head; can be done by adding a small amount of iron, which has good plasticity and is easy to process; Shi Xi' to improve the fluidity of molten metal.
