Abstract

A golf club head includes a striking face portion, and an aft body portion. The striking face portion includes a titanium alloy including four or more beta (β) stabilizers and one or more alpha (α) stabilizers. Each of the four or more beta (β) stabilizers is independently present in the titanium alloy in an amount of about 0.25 to about 1.75 wt %. A titanium alloy includes titanium, four or more beta (β) stabilizers, and one or more alpha (α) stabilizers.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A golf club head, comprising:
 a striking face portion, and   an aft body portion,   the striking face portion comprising a titanium alloy comprising four or more beta (β) stabilizers and one or more alpha (α) stabilizers, each of the four or more beta (β) stabilizers being independently present in the titanium alloy in an amount of about 0.25 to about 1.75 wt %.   
     
     
         2 . The golf club head of  claim 1 , wherein each of the four or more beta (β) stabilizers is independently present in the titanium alloy in an amount of about 0.5 to about 1.5 wt %. 
     
     
         3 . The golf club head of  claim 1 , wherein each of the four or more beta (β) stabilizers is independently present in the titanium alloy in an amount of about 0.75 to about 1.25 wt %. 
     
     
         4 . The golf club head of  claim 1 , wherein the four or more beta (β) stabilizers comprise Mn. 
     
     
         5 . The golf club head of  claim 1 , wherein each of the four or more beta (β) stabilizers is present in the titanium alloy in generally the same amount. 
     
     
         6 . The golf club head of  claim 1 , wherein the one or more alpha (α) stabilizers comprises Al. 
     
     
         7 . The golf club head according to  claim 6 , wherein the titanium alloy comprises an amount of Al of about 7 to about 10 wt %. 
     
     
         8 . The golf club head of  claim 1 , wherein the titanium alloy has a composition selected from the group consisting of:
