Golf club head structure for improving casting fluidity in a slurry shell

Abstract

A golf club head structure includes a first portion and a second portion adjacent thereto. The first portion and the second portion have a first thickness and a second thickness respectively. The ratio of the first thickness to the second thickness ranges between 0.56 and 1.00 that may enhance casting fluidity of molten iron in a slurry shell to thereby reduce the possibility of generating contraction cavities and slag-eyes in the golf club head.

1 . A golf club head made of Fe—Mn—Al alloy, comprising: 
 a club head body having at least two adjacent portions located at a reference point;    the two adjacent portions having a first thickness and a second thickness with respect to the reference point;    the ratio of the first thickness to the second thickness ranging between 0.56 to 1.00 that improves casting fluidity of molten iron of Fe—Mn—Al alloy to reduce the possibility of generating contraction cavities and slag-eyes in slush casting;    
   
   
       2 . The golf club head as defined in  claim 1 , wherein the club head body is an iron-type club head.  
   
   
       3 . The golf club head as defined in  claim 2 , wherein the club head body has a thickness ranging from 2 mm to 6 mm.  
   
   
       4 . The golf club head as defined in  claim 2 , wherein further comprising a weight member welding to the club head body.  
   
   
       5 . The golf club head as defined in  claim 1 , wherein the club head body is a pitching wedge or a sand wedge.  
   
   
       6 . The golf club head as defined in  claim 5 , wherein the club head body has a thickness ranging from 2 mm to 17 mm.  
   
   
       7 . The golf club head as defined in  claim 1 , wherein the club head body is a wood-type club head.  
   
   
       8 . The golf club head as defined in  claim 7 , wherein the club head body has a thickness ranging from 1 mm to 3 mm.
