Embodiment Construction
[0027]A golf club head alloy according to the present invention can be used to produce various parts of a golf club, preferably the string plate of a golf club head. The composition of the golf club head alloy and the method using the golf club head alloy to produce a sheet material for a striking plate of a golf club head will now be described.
[0028]The golf club head alloy includes 7-9.5 wt % of aluminum, 0.5-2 wt % of vanadium, 0.05-0.4 wt % of silicon, less than 0.4 wt % of iron, less than 0.15 wt % of oxygen, less than 0.1 wt % of carbon, less than 0.05 wt % of nitrogen, with the rest being titanium. The golf club head alloy has a density of 4.32-4.35 g / cm3.
[0029]In this example, the golf club head alloy preferably includes 7.5-8.5 wt % of aluminum, 1.0-1.5 wt % of vanadium, 0.15-0.25 wt % of silicon, 0.25-0.4 wt % of iron, less than 0.15 wt % of oxygen, less than 0.1 wt % of carbon, less than 0.05 wt % of nitrogen, and 89-91 wt % of titanium. The density of the golf club head ...

Abstract
A golf club head alloy includes 7-9.5 wt % of aluminum, 0.5-2 wt % of vanadium, 0.05-0.4 wt % of silicon, less than 0.4 wt % of iron, less than 0.15 wt % of oxygen, less than 0.1 wt % of carbon, less than 0.05 wt % of nitrogen, with the rest being titanium. The golf club head alloy has a density of 4.32-4.35 g / cm3. A method uses the golf club head alloy to produce a sheet material for a club head striking plate and for a golf club head. The method includes smelting the golf club head alloy into a titanium alloy rod, and repeatedly heating the titanium alloy rod and forging the titanium alloy rod into a flat blank. The flat blank is hot rolled to form a thin blank, wherein the flat blank has a reduction ratio of 70-75%. The thin blank is cold rolled into an alloy sheet material, and the alloy sheet material is annealed to form a sheet material for a club head striking plate and for a golf club head.
Description
CROSS REFERENCE TO RELATED APPLICATIONS[0001]This is a continuation-in-part application of U.S. patent application Ser. No. 13 / 946,021 filed on Jul. 19, 2013.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a golf club head alloy and a method for producing a sheet material for a striking plate of a golf club head and for the golf club head by using the golf club head alloy and, more particularly, to a low-density, high-toughness golf club head alloy and a method for producing a durable sheet material for a striking plate of a golf club head and for the golf club head by using the golf club head alloy.[0004]2. Description of the Related Art[0005]Conventionally, the parts of a golf club head, such as the club head body, the striking plate, the lid or the weights, are generally produced through precision casting of stainless steel, such as SUS630 or SUS431 (type 630 or type 431 according to American Iron and Steel Institute). However, due...
