Fe-Mn-Al alloy club body combining with a Ti alloy striking plate

Abstract

A golf club head structure includes a Fe—Mn—Al alloy club body and a Ti alloy striking plate. The Fe—Mn—Al alloy club body connects to the Ti alloy striking plate by press-fitting or brazing so that the combined club head structure obtains lower Young's modulus to transmit a complete striking stress from the Fe—Mn—Al alloy club body to the Ti alloy striking plate while striking a golf ball. The Fe—Mn—Al alloy club body can eliminate vibration to maintain high elastic deformation of the Ti alloy striking plate while striking a golf ball. Furthermore, a W—Fe—Ni alloy weight member connects to the Fe—Mn—Al alloy club body by welding since Fe—Mn—Al alloy performs excellent heterogeneous welding ability.

1 . A golf club head comprising: 
 a Fe—Mn—Al alloy club body; and    a Ti alloy striking plate mounted to the Fe—Mn—Al alloy club body to constitute a combined member of the golf club head;    wherein when striking a golf ball, the combined member of the golf club head can return a striking stress from the Fe—Mn—Al alloy club body to the Ti alloy striling plate that improves the elastic deformation of the Ti alloy striking plate and the striking ability of the Fe—Mn—Al alloy club body.    
   
   
       2 . The golf club head as defined in  claim 1 , wherein the Ti alloy striking plate is combined with the Fe—Mn—Al alloy club body by a punching machine.  
   
   
       3 . The golf club head as defined in  claim 1 , wherein the Ti alloy striking plate connects to the Fe—Mn—Al alloy club body in a brazing process.  
   
   
       4 . The golf club head as defined in  claim 1 , wherein the Fe—Mn—Al alloy club body further includes a compartment adapted to accommodate a weight member.  
   
   
       5 . The golf club head as defined in  claim 4 , wherein the weight member made of heavier material with specific gravity greater than 10.0 g/cm 3  selected from W alloy or W—Fe—Ni alloy relative to Fe—Mn—Al alloy.  
   
   
       6 . The golf club head as defined in  claim 4 , wherein the weight member is mounted in the compartment of the Fe—Mn—Al alloy club body in a welding process.  
   
   
       7 . The golf club head as defined in  claim 6 , wherein the welding process is selected from a group consisting of gas tungsten arc welding, brazing, laser beam welding, plasma arc welding and ion beam welding.
