Golf club head

Abstract

The invention relates to a golf club head which comprises a front side shell and a rear side shell that are connected to form a club head shell; wherein, the front side shell is made of metal with better elasticity like titanium alloy or maraging steel or stainless steel and so on, and is provided with a striking surface. The front side shell extends a ring wall part from the rear part of the striking surface, which on the whole looks like a cup. A scarf joint part is arranged on the outer end of the wall part. The distance between the striking surface of the wall part and the outer end of the wall part is equal to or larger than 8cm, while the thickness of the wall part is equal to or less than 2cm. The rear side shell is made of lightweight metal with lighter proportion like magnesium alloy or aluminum alloy and so on, which on the whole looks like a deep cup. A scarf joint part is arranged on the opening end edge for mutually scarf jointing with the scarf joint part of the front side shell, and the neck part of the club head shell is arranged on the front side shell. The golf club head overcomes the connections problem between the titanium alloy or stainless steel striking surface and the magnesium alloy or aluminum alloy shell.

Description

technical field [0001] The present invention relates to a golf club head, in particular to a golf club head using a light alloy such as magnesium or aluminum as a shell. Background technique [0002] The golf club head shell formed by light alloy such as magnesium or aluminum has the advantages of light weight, and it is easy to design a super large and low center of gravity club head, especially the magnesium alloy has good shock absorption, as the club head shell has its own its advantages. However, the strength of magnesium alloy is poor, so it is not suitable for the hitting surface. Therefore, the hitting surface must be made of materials with better elasticity, such as titanium alloy or stainless steel. However, the melting point of magnesium or aluminum alloy is low, so titanium alloy or The hitting surface of stainless steel cannot be joined with the housing of magnesium or aluminum alloy by brazing, nor can it be joined by general welding. Because the materials of ...

Problems solved by technology

However, the strength of magnesium alloy is poor, so it is not suitable for the hitting surface. Therefore, the hitting surface must be made of materials with better elasticity, such as titanium alloy or stainless steel. However, the melting point of magnesium or aluminum alloy is low, so titanium alloy or The stainless steel hitting surface cannot be brazed with the magnesium or aluminum alloy shell, nor can it be joined by ordinary welding. Because the materials of the two are different, the strength of the welded joint is insufficient and the joint effect is poor.
