Golf club head

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.
