Benefits of technology

[0011]Therefore, an object of the present invention is to provide a golf club head that is lightweight, has good mechanical properties, and has a CT value close to the upper limit (257 μsec) regulated by the USGA and a strength close to the lower limit (3000 hits) of the strength standard of the faces of commercial golf clubs.
[0016]Because the striking front face plate of the front striking portion is made from the rolled titanium-based alloy with a relatively low density and a relatively high Young's modulus, it can achieve effects including lightweight, good mechanical strength and abrasion resistance, and can comply with the regulations of the USGA. Therefore, the golf club head of the present invention can have a reduced total weight such that a center of gravity thereof may be easily adjusted using a weight unit, while complying with the regulations of the USGA related to a golf club head.

Problems solved by technology

However, the CT value of the face will increase as a result of reduction of strength caused by decrease in the thickness.

Embodiment Construction

[0021]Before the present invention is described in greater detail with reference to the accompanying preferred embodiments, it should be noted herein that like elements are denoted by the same reference numerals throughout the disclosure.

[0022]Referring to FIG. 1, a golf club head 1 according to the first preferred embodiment of this invention comprises a back portion 11 and a front striking portion 12 connected to the back portion 11. The front striking portion 12 includes a striking front face plate 121 connected to the back portion 11 and has a thickness ranging from 1.0 mm to 4.2 mm. A total volume of the back portion 11 and the striking front face plate 121 ranges from 300 cc to 460 cc. A total weight of the back portion 11 and the striking front face plate 121 ranges from 170 grams to 220 grams.

[0023]The striking front face plate 121 is made by rolling a titanium-based alloy (811 Ti alloy) . Preferably, the 811 Ti alloy has a density ranging from 4.35 g / cm3 to 4.36 g / cm3, a te...

Abstract

A golf club head includes: a back portion; and a front striking portion connected to the back portion and having a thickness ranging from 1.0 mm to 4.2 mm. The front striking portion includes a striking front face plate that has a characteristic time ranging from 220 μ sec-257 μsec. The front striking portion is made by rolling a titanium-based alloy and the titanium-based alloy has a density ranging from 4.35 g / cm3 to 4.36 g / cm3, a tensile strength ranging from 130 ksi to 146 ksi, a yield strength ranging from 120 ksi to 132 ksi, and a Young's modulus ranging from 120 Gpa to 135 Gpa. A total volume of the back and front striking portions ranges from 300 cc to 460 cc, and a total weight of the back and front striking portions ranges from 170 grams to 220 grams.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to a golf equipment, and more particularly to a golf club head.[0003]2. Description of the Related Art[0004]Golf sport involves a player twisting his / her waist to swing a golf club and strike a golf ball. Thus, in addition to having relatively high strength and abrasion resistance to enhance stroke stability, the golf club is required to have a suitable weight to minimize player fatigue when swinging the same.[0005]Consequently, the golf equipment industry has been aggressive in searching, developing and designing new materials and manufacturing procedures for golf club heads. In particular, current major research and development of the golf equipment industry focus on preparation of the golf club head having various properties with alloys of different compositions. A golf club head made of 6Al-4V Ti alloy is most popular in recent years, since it has good mechanical strength as shown in Table 1 a...
