Benefits of technology
The present invention is a golf club head made of two different materials that have different properties. The main body is made of a first material, while the club portion is made of a second material that has higher ductility. This results in a golf club head that has a preferred damping effect and a high coefficient of rebound. Additionally, the use of different materials reduces manufacturing costs.
Problems solved by technology
The prices of these materials are usually expensive.
Therefore, the manufacturing cost is relatively high for the conventional golf club head 1.
With the high rigidity material, it is not only quite difficult to adjust the angle between the club portion 112 and the hitting plate 12 but also easily results in the crack and damage of the main body 11.
In addition, the main body 11 made of a material with a higher rigidity may also cause the golf club head 1 to have a poorer damping effect and a lower coefficient of rebound, and as a result, the hitting effect is reduced and the golfer has a poor hitting sense.

first embodiment
[0020]In the first embodiment, the main body 21 is integrally formed and has a hitting surface 212, wherein the first material of the main body 21 is a stainless steel or a titaniumalloy, and the main body 21 is formed by casing, forging, or machining. The second material of the club portion 22 is a soft iron, a cast iron, or a Fe / Mn / Al alloy, and the club portion 22 is formed by casing, forging, or machining.
[0021]It should be noted that, in the first embodiment, the golf club head 2 is an iron head, and in other applications, the golf club head 2 may also be a putter head or a wood head (as shown in FIG. 3).
[0022]The second material has a higher ductility than the first material, so after the main body 21 and the club portion 22 are jointed together, the club portion 22 has the function of adjusting the angle, and the golf club head 2 has a preferred damping effect and a high coefficient of rebound. Furthermore, the golf club head 2 is formed by the main body 21 and the club port...
second embodiment
[0025]The main portion 311 is made of the stainless steel or titaniumalloy, and the hitting plate 312 is made of titanium alloy, stainless steel, Fe / Mn / Al alloy or aluminum alloy. The main portion 311 and the hitting plate 312 are formed by casting, forging, or machining. In the second embodiment, the main portion 311 and the hitting plate 312 are jointed by 3D welding, or they may be jointed together by welding, brazing, soldering, bonding, or friction stir welding.
[0026]It should be noted that, in the second embodiment, the golf club head 3 is an iron head, and in other applications, the golf club head 3 may also be a putter head or a wood head (as shown in FIG. 5).
[0027]The club portion 32 (the second material) of the golf club head 3 in the second embodiment has a higher ductility as compared with the main portion 311 and the hitting plate 312 (the first material), so that the club portion 32 has the function of adjusting the angle. Similar to the golf club head 2 of the first ...

Abstract
A golf club head is provided. The golf club head comprises a main body and a club portion. The main body has a first junction surface, and the main body is made of a first material. The club portion has a second junction surface, the second junction surface is used to be jointed with the first junction surface, and the club portion is made of a second material. The second material and the first material are substantially different materials. As compared with the first material, the second material has a higher ductility, so after the main body and the club portion are jointed, the club portion has the function of adjusting the angle, the golf club head has a preferred damping effect and a high coefficient of rebound, so as to solve the problem that the integrally-formed main body and the club portion of the conventional golf club head must be manufactured with plenty of expensive material, and to reduce the manufacturing cost.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a golf club head. More particularly, the present invention relates to a golf club head with a club portion and a main body made of different materials.[0003]2. Description of the Related Art[0004]FIG. 1A is a schematic exploded view of a conventional golf club head, and FIG. 1B is a schematic combined view of the conventional golf club head. Referring to FIGS. 1A and 1B, the conventional golf club head 1 comprises a main body 11 and a hitting plate 12. The main body 11 is integrally formed and has a notch 111 and a club portion 112. The shape of the hitting plate 12 matches with the shape of the notch 111, and then, the hitting plate 12 and the notch 111 are jointed together through welding, brazing, or other mechanical jointing manners.[0005]Generally, in conventional manufacturing process, the main body 11 having the club portion 112 is integrally formed by the same material such as st...
