Benefits of technology

[0005]The primary objective of the present invention is to provide a golf club head, which a housing made of magnesium alloy or aluminum alloy and a face made of titanium alloy or stainless have a strong bonding strength therebetween without the drawback as described above.

Problems solved by technology

But, magnesium alloy has a weak strength that is not suitable for the face.
However, magnesium alloy or aluminum alloy has a lower melting temperature than titanium alloy and stainless, so that the titanium alloy or stainless face can't bond to the magnesium alloy or aluminum alloy housing by brazing or other conventional welding.

Embodiment Construction

[0012]As shown in FIG. 1 to FIG. 4, a golf club head 10 of a first preferred embodiment of the present invention includes a front member 20 and a rear member 30.

[0013]The front member 20 is made of a flexible material, such as aluminum alloy, stainless or Maraging steel. The front member 20 has a face 21 and an annular wall 22 projected from a back of the face 21. The front member 20 is a cup-like member. The annular wall 22 has a connecting portion at a distal end. As shown in FIG. 3, a length W of the wall 22 is identical to or greater than 8 mm, and a thickness D thereof identical to or less than 2 mm. In the present embodiment, the length is 10 mm, and the thickness D is 1.5 mm.

[0014]The rear member 30 is made of a light material, such as magnesium alloy or aluminum alloy. The rear member 30 is a cup-like member also with a greater depth. The rear member 30 has a connecting portion 31 at an open end to be engaged with the connecting portion 23 of the front member 20. As shown in...

Abstract

A golf club head includes a front member, a rear member and a neck connected together to form a housing. The front member, which is made of a flexible material, such as aluminum alloy, stainless or Maraging steel, has a face and an annular wall projected from a back of the face to form a cup-like member, wherein the wall has a connecting portion at a distal end thereof, and a length of the wall is identical to or greater than 8 mm and a thickness of the wall is identical to or less than 2 mm. The rear member, which is made of a light metal, such as magnesium alloy or aluminum alloy, has a connecting portion to engage the connecting portion of the front member. The neck is fixed on the rear member.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to a golf club, and more particularly to a golf club head made of light alloy, such as magnesium alloy or aluminum alloy.[0003]2. Description of the Related Art[0004]A golf club head, which a housing thereof is made of magnesium alloy or aluminum alloy, has many advantages, such as light weight, greater size and lower center of gravity. Especially for a magnesium alloy golf club head, it has a superior vibration absorbing capacity. But, magnesium alloy has a weak strength that is not suitable for the face. To overcome this issue, the face is usually made of the alloy with superior flexibility, such as titanium alloy or stainless. However, magnesium alloy or aluminum alloy has a lower melting temperature than titanium alloy and stainless, so that the titanium alloy or stainless face can't bond to the magnesium alloy or aluminum alloy housing by brazing or other conventional welding...
