US Patent 7431664 Composite metal wood club

A metal wood golf club head adapted for attachment to a shaft, comprising of a body portion composed of titanium alloy and a graphite crown portion, each portion constructed of a different density material. Combining a high-density material in the body portion, with a low-density material in the crown portion, creates an ultra-low center of gravity relative to the geometric face center, resulting in higher launch angles and spin rate ratios. The body portion has an attachment ledge section and the crown portion has attachment section that overlays the attachment section of the body. A vibration dampening gasket is disposed between the attachment sections.
