Abstract

Embodiments of golf club weight attachment mechanisms are described herein. In some embodiments, a golf club head comprises a head body with an interior cavity, a shell portion, and a bracket with a weight member coupled to the bracket. In one embodiment, the bracket and the weight member can be configured to be fully contained within the interior cavity. Other examples and related methods are also described herein.

Claims

1. A golf club head comprising:

a body comprising a receptacle;

a multi-density weight comprising;

a first weight component comprising a first density; and

a second weight component comprising a second density greater than the first density;

wherein;

the first weight component is configured to receive the second weight component;

the multi-density weight is configured to couple to with the receptacle;

the first weight component comprises a tungsten alloy;

the second weight component comprises a tungsten alloy having a weld-averse trait with respect to the body;

the second weight component is at least partially bounded by the first weight component; and

a thickness of the first weight component around the second weight component is at least 0.075 inch.

2. The golf club head of claim 1, wherein the second weight component is coupled to the first weight component with a swedged bond.

3. The golf club head of claim 1, wherein the multi-density weight is coupled to the receptacle of the body with a weld bond.

4. The golf club head of claim 1, wherein the multi-density weight is coupled to the receptacle of the body with a brazed bond.

5. The golf club head of claim 1, wherein the second weight component comprises greater than 70% of a total volume of the multi-density weight.

6. The golf club head of claim 1, wherein the multi-density weight forms a portion of a backside of the body.

7. The golf club head of claim 1, wherein the multi-density weight forms portion of a backside and a toe region of the body.

8. The golf club head of claim 1, wherein the multi-density weight forms a portion of a backside, a toe region, and a sole region of the body.

9. The golf club head of claim 1, wherein the multi-density weight forms a portion of a sole region and a toe region of the body.

10. The golf club head of claim 1, wherein the first weight component comprises a density of less than 13 g/cm³ and the second weight component comprises a density of greater than 11 g/cm³.

11. A golf club head comprising:

a body comprising a receptacle;

a multi-density weight comprising;

a first weight component comprising a first density; and

a second weight component comprising a second density greater than the first density;

wherein;

the first weight component is configured to receive the second weight component;

the multi-density weight is configured to couple to with the receptacle;

the first weight component comprises a tungsten alloy;

the second weight component comprises a tungsten alloy having a weld-averse trait with respect to the body;

the first weight component partially bounds the second weight component;

a thickness of the first weight component around the second weight component is at least 0.075 inch; and

the multi-density weight forms a portion sole region and a toe region of the body.

12. The golf club head of claim 11, wherein the second weight component is coupled to the first weight component with a swedged bond.

13. The golf club head of claim 11, wherein the multi-density weight is coupled to the receptacle of the body with a weld bond.

14. The golf club head of claim 11, wherein the multi-density weight is coupled to the receptacle of the body with a brazed bond.

15. The golf club head of claim 11, wherein the second weight component comprises greater than 70% of a total volume of the multi-density weight.

16. The golf club head of claim 11, wherein the first weight component completely bounds the second weight component.

17. The golf club head of claim 11, wherein the multi-density weight forms a portion of a backside and a toe region of the body.

18. The golf club head of claim 11, wherein the multi-density weight forms a portion of a backside, a toe region, and a sole region of the body.

19. The golf club head of claim 11, wherein the first weight component comprises a density of less than 13 g/cm³ and the second weight component comprises a density of greater than 11 g/cm³.
