Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion with a toe portion, a top portion, a sole portion, and a back portion. The back portion may be include a back wall portion. The golf club head may also include a face portion, an interior cavity, at least one weight portion, and at least one port. The interior cavity may be partially or entirely filled with a polymer material. Other examples and embodiments may be described and claimed.

A composite material golf club head is provided having a body made from a first metal and a face insert press fitted to a portion of the body and made from a second metal The metals are chosen so that the first metal is heavier than the second metal. The second metal is disposed towards the front and top of the body, and is preferably hard-anodized. In addition, an interlocking structure, for example rectangular or dove tail shaped channels, is provided in the body so that the face insert becomes embedded in the interlocking structure to anchor the face insert to the body. Portions of the golf club head, such as the face insert or sole plate, are anodized to protect against corrosion. The anodized coating is colored to improve aesthetic characteristics or infused with a polymer to increase or reduce friction. Disclosed herein is a golf club head having a body portion and a face insert. The front of the body portion further comprises a cutout sized and dimensioned to receive the face insert. The body portion is preferably made from a high-strength metal such as stainless steel, titanium or titanium alloy. The face insert is preferably comprised of a metal having a lower density than that of the body portion. The face insert comprises an aluminum metal matrix composite (MMC) containing an amount of scandium and zirconium. The golf club head may also include a top line insert made of a lightweight material and at least one heavy weight member disposed to the back of the club head.

Disclosed herein are various embodiments of a golf club head having improved mass distribution characteristics. The golf club head includes a body and a face positioned at a forward portion of the body. The golf club head also includes one or more mass elements positioned at predetermined locations about the head. The mass elements assist in achieving a desired relationship between the moment of inertia about a center of gravity x-axis and the moment of inertia about a center of gravity z-axis.

Embodiments of golf club heads, golf clubs, and methods to manufacture golf club heads and golf clubs are generally described herein. In one example, a golf club head may include a body portion, and an internal mass portion comprising a material having a greater density than a material of the body portion, a height in a top-to-sole direction, a depth in a front-to-back direction, and a width in a toe-to-heel direction. The distance between the internal mass portion and a toe portion edge is substantially less than the distance between the internal mass portion and a heel portion edge. The volume of the internal mass portion increases in a top-to-sole direction, and the height of the internal mass portion is greater than the width of the internal mass portion. Other examples and embodiments may be described and claimed.

The sole cavity ports described herein can have varying thicknesses across the cavity port lengths. In some embodiments, the golf club heads described herein can have a weight insertable into the sole port, wherein the weight can comprise a variable density. Other examples and related methods are also disclosed herein.

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion having a front portion, a rear portion, a toe portion, a heel portion, a top portion, and a bottom portion. The golf club head may include a sealed cavity located behind a face portion. A polymer insert and a filler material may be contained within the sealed cavity. Other examples and embodiments may be described and claimed.

A golf club head has a body having a ball striking face, a rear opposite the ball striking face, a crown, a sole, a heel, and a toe, the body having a void defined by a peripheral edge on the sole. The body further defines a cover that extends over the void and forms at least a portion of the crown. At least a portion of the peripheral edge of the void includes a lip extending from the peripheral edge inwardly into the void. The golf club head may additionally or alternately include one or more weight receptacles connected to the sole and having an opening in the sole, such that each weight receptacle is configured to receive insertion of a weight through the opening.
