New description: [New technical field] This is a golf club head, especially a golf club head with a high-strength aluminum alloy striking panel. [Prior Art] - Corresponding to different numbers, the weight of the Schottky club head is about its fixed specification value. For example, the golf club head of #5 weighs about 256 grams. In the prior art, A has adjusted the position of the center of gravity, and the high-strength unrecorded steel is used to manufacture the striking panel. Although the thickness of the striking panel can be reduced to 2.lmm by using (4) steel, the golf club head with a total weight of about 244·87 g is: The weight of the hitting panel of Luan Steel is about 57.59 grams. The proportion of the weight of the golf club head is quite high, and the adjustment of the center of gravity of the golf club head is not ideal. In order to adjust the position of the center of gravity of the golf club head for better hitting performance, it is necessary to save more weight from the striking panel' and save the impact panel when the total weight of the golf club head remains unchanged. The weight is reconfigured in the rest of the ball head 'by changing the position of the center of gravity of the golf club head. Since the density of the titanium alloy is about 4_5g/cm3, when a titanium (Ti) alloy is used to manufacture the striking panel, the golf club head having the total weight of about gram can be used as an example, and the striking panel can be used (the thickness is about 2.8 mm). The weight is reduced to approximately 44.46 grams. In terms of density alone, the material for making the impact panel is Ming alloy, which has a density of about 2.7 g/em3. Although it can theoretically reduce the weight of the M355111 hitting panel, the golf hitting panel is used for direct contact and impact on the golf ball in addition to the density and weight. Therefore, other considerations are needed. Mechanical properties such as strength, ductility, and toughness, which are primarily related to the fatigue life of the impact panel of a golf club head. Among the conventional high-strength aluminum alloys, for example, the 7-75th precipitation hardening type aluminum alloy of the 7 series is still insufficient in mechanical properties, and it is necessary to conform to the demand of the golf club head by thickening the thickness of the striking panel. Therefore, the conventional high-strength aluminum alloy cannot effectively reduce the weight of the striking panel and thereby adjust the position of the center of gravity of the golf club head. [New content] Therefore, the purpose of this creation is to provide a golf club head with a high-strength aluminum alloy striking panel, which can effectively reduce the thickness of the striking panel to achieve the purpose of adjusting the center of gravity of the golf club head. In order to achieve the above objectives, the present invention provides a golf club head of a high-strength alloy hitting panel. The golf club head includes at least a striking panel and a body. The striking panel has a striking surface for hitting the golf ball, and the thickness of the striking panel is between 2.7〇1111 and 37 mm. The main body forms the rest of the golf club head of the high-strength aluminum alloy striking panel. In the golf club head of the present invention, the high-strength aluminum alloy body in which the high-strength aluminum alloy striking panel is made contains 0 〇 6% or less, 〇丨% or less of Fe'2 to 2.5% of Cuq. 5 〜 2 5% of Mg, 5 to 95% of Zn, 〇〇5% or less of Μη '〇.1~〇2% of Zr, 0.05% or less of 〇, 〇.〇5. /. The following h' 〇.〇1~〇.1% of Sc, and the remaining % of A, where % means weight M355111%' and the weight ratio of Zn to Mg is between 3.2 and 4.4. The advantage of this creation is that the design of the center of gravity of the golf club head can be given more freedom in the case of a thinner aluminum alloy striking panel that meets the needs of the golf club head. [Embodiment] Figs. 1A and 1B show a golf club head 1' according to an embodiment of the present invention, which includes a striking panel 102 and a main body 1〇4. The main body can be carbon steel (such as S20C or S25C carbon steel), stainless steel (such as i7_4pH stainless steel), alloy steel, iron-manganese alloy, nickel-based alloy, cast iron, super alloy steel, pure titanium, titanium alloy (such as Ti6A14V or CPTi titanium alloy). ), metal materials such as aluminum alloys, magnesium alloys, or copper alloys. The striking panel 1〇2 and the main body 104 can be integrally molded by casting, powder sintering, forging, or machining. In addition, the golf club head 1 of the present invention can integrally cast the main body ι 4 having the opening of the striking panel 1〇2 by dewaxing, and then arrange and weld the striking panel 1〇2 to the striking surface of the main body 104. Step 2: The two finished products can be further subjected to Grinding, Polishing or Age Hardening. The striking panel 1 〇2 to be welded to the main body 1 can be formed by extrusion, casting or rolling. Referring to FIG. 1B, the striking panel 1〇2 has a striking surface 1〇2a for striking a golf ball, and the striking surface i〇2a of the striking panel 1〇2 is provided with a plurality of horizontally extending face grooves ( Sc〇re Lines) 丨〇 2b, these face grooves l 〇 2b are substantially parallel to the bottom 丨 (10) of the golf club head 1 。. Further, in the Nalph club head 100, the M355111 is constituted by the main body 104 except for the striking panel 1〇2. In this embodiment, the surrounding area l〇2c of the striking panel 1〇2 (relative to the striking surface 1〇2a (refer to FIG. 1B)) is fixed to the main body 1G4, and other areas of the m position are It is exposed by the through holes 1 〇 4b of the main body 104. 2 is a golf club head 200' according to another embodiment of the present invention, which is substantially identical to the golf club head 1 , except that the golf club head 200 further includes a bottom portion of the body 1 1〇6 weight block 丨 (10). The weight 108 can be made of a material having a specific gravity greater than that of the head body, for example, a crane alloy, a crane alloy, a steel alloy or the like, and can be made by casting, forging, powder metallurgy or the like. It is suitable for the manufacture of high-strength alloys of this type of hitting panels. The series is shown in Table 1 below.
下 ~~~~Z,n:mg I 七2〜4 述高強度鋁合金所含成分及含量限定之理由敘述 在本創作高強度鋁合金中，Si與Fe係視為在特定令 下允°午存在之雜質。若Si含量太高時，Si在鋁合金中, 成Sl析出物或與Sc結合而形成ScSi或Sc2A1Si2的析注 M355111 並影響鋁合金的機械性質表現，故Si含量較佳係佔高強度 铭合金整體重量之0.06%以下。過高的Fe含量將使得高強 度铭合金中形成AlsFe的析出物，除了會降低鋁合金的再 結晶温度外，這些析出物也容易形成裂縫的起源而降低了 鋁合金的破裂韌性，故Fe含量較佳係不超過高強度鋁合金 整體重量的0.1%。 在本創作之高強度鋁合金中，添加適量的Cu，除了能 夠有效地形成化合物CuAl2並促進Gp g(Guinier_Prest〇nLower ~~~~Z,n:mg I 七2~4 The reason for the limitation of the composition and content of the high-strength aluminum alloy is described in the high-strength aluminum alloy of this creation, Si and Fe are considered to be under a specific order. Impurities present in the afternoon. If the Si content is too high, Si is precipitated in the aluminum alloy or combined with Sc to form ScSi or Sc2A1Si2, which affects the mechanical properties of the aluminum alloy, so the Si content is better than the high strength alloy. The overall weight is less than 0.06%. Excessively high Fe content will cause AlsFe precipitates to form in high-strength alloys. In addition to lowering the recrystallization temperature of aluminum alloys, these precipitates are also prone to the origin of cracks and reduce the fracture toughness of aluminum alloys. Preferably, it does not exceed 0.1% of the overall weight of the high strength aluminum alloy. In the high-strength aluminum alloy of this creation, an appropriate amount of Cu is added, in addition to being able to effectively form the compound CuAl2 and promote Gp g (Guinier_Prest〇n
Zone)的开^成之外，更有助於提升高強度鋁合金常溫時的延 伸率，藉此可增加所製成打擊面板〗〇2之韌性，並提升打 擊面板102之低週疲勞壽命（L〇w Cycle Fadgue Ufe)。在本 創作中’ Cu之含量較佳係介於高強度鋁合金整體重量的2〇/〇 至2.5%之間，可提升打擊面板1〇2之高強度鋁合金常溫時 的延伸率1%〜2%。當Cu含量過低（低於2%)時，則無法有 =改善高強度銘合金的勒性。當Cu含量過高（高於25%) 時，則會增加焊接時的熱裂敏感性。 A兩的Zn §罝有助於淬火反應（Quenching Reacti〇n) 的進行&為了使得高強度銘合金擁有較佳的泮火反應， 故=旦本創作之打擊面板1〇2所使用之高強度紹合金中的 3里在較佳之實施例中，Ζη的重量佔打擊面板j 〇2整 人重里係’丨於5%至9 5%之間。Zn含量愈高則愈難克服銘 、在疑固過私中的熱裂問題，故Zn含量較佳係佔高強度 鋁合金整體重量之9 5%以下。In addition to the opening of the Zone, it is more helpful to increase the elongation of the high-strength aluminum alloy at normal temperature, thereby increasing the toughness of the finished panel and improving the low-cycle fatigue life of the striking panel 102 ( L〇w Cycle Fadgue Ufe). In this creation, the content of Cu is preferably between 2〇/〇 and 2.5% of the total weight of the high-strength aluminum alloy, which can increase the elongation of the high-strength aluminum alloy hitting the panel of 1〇2 at room temperature by 1%~ 2%. When the Cu content is too low (less than 2%), there is no way to improve the strength of the high-strength alloy. When the Cu content is too high (above 25%), the thermal cracking sensitivity during welding is increased. A Zn § 罝 helps the quenching reaction (Quenching Reacti〇n) to proceed & In order to make the high-strength alloy have a better smoldering reaction, the height of the hitting panel 1 〇 2 is used. 3 of the strength of the alloy In the preferred embodiment, the weight of Ζη is between 5% and 95% of the weight of the striking panel j 〇2. The higher the Zn content, the more difficult it is to overcome the thermal cracking problem in the case of doubt and privacy. Therefore, the Zn content is preferably less than 95% of the total weight of the high-strength aluminum alloy.
Mg是鋁合金中的一種主要析出強化相。吨含量佔高 又、呂口金整體重$較佳係介於15%至2 5%之間。若叫 M355111 含里太南（大於2.5。/。）時，會降低對應力腐蝕的抵抗能力。 反之’若Mg含量太低（小於1.5%)時’會降低機械性質。 另外’為了提高I呂合金的機械性質（例如：抗拉強度）， 本創作將打擊面板102之高強度鋁合金中Zn與Mg含量之 重量比設定在3.2至4.4之間。高強度鋁合金中Zn與Mg 含篁之重量比的提高，除具有較高之強度外，更可以有效 地形成Al-Zn-Mg化合物，以增加高強度鋁合金的抗腐蝕Mg is one of the main precipitation strengthening phases in aluminum alloys. The ton content is high, and the overall weight of Lukoujin is between 15% and 25%. If M355111 is contained in Tainan (greater than 2.5%), it will reduce the resistance to stress corrosion. On the contrary, if the Mg content is too low (less than 1.5%), the mechanical properties are lowered. In addition, in order to improve the mechanical properties of the Ilu alloy (for example, tensile strength), the present invention sets the weight ratio of Zn to Mg in the high-strength aluminum alloy of the striking panel 102 to be between 3.2 and 4.4. In the high-strength aluminum alloy, the weight ratio of Zn to Mg yttrium is increased, in addition to the higher strength, the Al-Zn-Mg compound can be effectively formed to increase the corrosion resistance of the high-strength aluminum alloy.

Therefore, the Zn/Mg ratio is too high or too low, which is not conducive to improving the stress crack resistance. The addition of Mn, Cr and Ti to the two strength alloys is mainly used to refine the crystal Mn Ti, although it contributes to the dispersion of precipitates and facilitates the refinement of grains, but the excessive content increases the quenching sensitivity, which is not conducive to heat treatment.

As can be seen from the data listed in Table 3, the high-strength aluminum alloy made of the present invention is used to make the impact panel, which is reduced by about 42.3%~55.5% compared with the conventional high-strength stainless steel; The alloy is reduced by about 25 〜% to 42.2% in weight. In addition, it has the golf club head made of the South Intensity Alloy made by this creation. The phase 13 M355111 is lower than the golf club head made of high-strength stainless steel. The overall weight is reduced by 4 degrees @ 12 G%~124 %; Compared with the golf club head made of tantalum alloy to hit the panel, the overall center of gravity is reduced by about 7.0% to 7.4%. In terms of the overall center of gravity of the golf club head, it is made of the high-strength alloy of the creation. The golf club head hitting the panel is increased by about 6.5%~6.7% compared with the golf club head which is known to be high-strength non-recorded steel to make the hitting panel; if it is made with the alloy (I), the high λ club Compared with the head, the increase is about 2.9%~3,1%. Please refer to the table again - as can be seen from Table 1, the tensile strength of the high-strength aluminum alloy used in this creation can even be as high as 122Ksi (the high-strength alloy used in the golf club head No. 5 in Table 1) . According to the trend of Figure 3, the golf club head number 5 in Table 1 is tested by the shelling test. The minimum thickness of the striking panel can be less than the 2.7 mm of the golf club head of the 3rd edition, but in actual In the experimental test, this trend is also met. However, in practical applications, the characteristics of the high-strength aluminum alloy used to make the impact panel are usually between the high-strength alloys used in the 3th "Towel No. 1 and No. 2 golf club heads", that is, the tensile strength. Between l〇9ksi and 94ksi, the minimum thickness that can be tested by shelling is between 2.7mm and 3.7mm. According to the above, the stress corrosion cracking sensitivity increases first and then increases with the increase of Zn/Mg ratio. Therefore, the Zn/Mg ratio is too high or too low to improve the stress corrosion cracking sensitivity. Therefore, Zn in Table 1 The weight ratio of the Mg content is set between 3.2 and 4.4. Based on the above description, the high-strength aluminum alloy developed by the present invention is applied to the production of the hitting panel of the golf club head, so that the tensile strength of the striking panel 14 M355111 is higher than that of the conventional one.
