Golf club head

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.

1 . A golf club head, comprising:
 a main body, having a first junction surface, wherein the main body is made of a first material; and   a club portion, having a second junction surface, wherein the second junction surface is used to be jointed with the first junction surface, the club portion is made of a second material, and the second material and the first material are substantially different materials.   
   
   
       2 . The golf club head according to  claim 1 , wherein as compared with the first material, the second material has a higher ductility. 
   
   
       3 . The golf club head according to  claim 1 , wherein the main body is integrally formed and has a hitting surface. 
   
   
       4 . The golf club head according to  claim 3 , wherein the first material is a stainless steel or a titanium alloy. 
   
   
       5 . The golf club head according to  claim 4 , wherein the main body is formed by casting, forging, or machining. 
   
   
       6 . The golf club head according to  claim 1 , wherein the second material is a soft iron, a cast iron or a Fe/Mn/Al alloy. 
   
   
       7 . The golf club head according to  claim 6 , wherein the club portion is formed by casting, forging, or machining. 
   
   
       8 . The golf club head according to  claim 1 , wherein the main body comprises a main portion and a hitting plate, the main portion has a notch, the shape of the hitting plate matches with the shape of the notch, and the hitting plate is disposed on the notch. 
   
   
       9 . The golf club head according to  claim 8 , wherein the main portion is made of a stainless steel or a titanium alloy. 
   
   
       10 . The golf club head according to  claim 8 , wherein the hitting plate is made of a titanium alloy, a stainless steel, a Fe/Mn/Al alloy or an aluminum alloy. 
   
   
       11 . The golf club head according to  claim 8 , wherein the main portion, the hitting plate, and the club portion are formed by casting, forging, or machining. 
   
   
       12 . The golf club head according to  claim 8 , wherein the main portion and the hitting plate are jointed by welding, brazing, soldering, bonding, friction stir welding, or three-dimensional (3D) welding. 
   
   
       13 . The golf club head according to  claim 1 , further comprising at least one weighting structure disposed in the main body. 
   
   
       14 . The golf club head according to  claim 13 , wherein the weighting structure is disposed at the bottom or at the back of the main body. 
   
   
       15 . The golf club head according to  claim 14 , wherein the weighting structure is a W/Ni alloy, a tungsten rubber, or a weighting screw. 
   
   
       16 . The golf club head according to  claim 14 , wherein the weighting structure is formed by casting, forging, machining, or powder metallurgy. 
   
   
       17 . The golf club head according to  claim 1 , wherein the first junction surface and the second junction surface are jointed by welding, brazing, soldering, bonding, friction stir welding, or 3D welding.
