  • the present invention provides a golf club head alloy that can be used to produce a light golf club head.
  • the present invention further provides a method of using the above golf club head alloy to produce a light golf club head.
  • a golf club head alloy according to the present invention includes by weight percent 6.5-7.5% of aluminum, 1.0-2.5% of iron, 0.05-0.2% of silicon, less than 0.15% of oxygen, less than 0.1% of carbon, less than 0.05% of nitrogen, the rest being titanium and inevitable impurities. Furthermore, the golf club head alloy has a density of 4.35-4.39 g/cm 3 . Preferably, the golf club head alloy includes by weight percent 6.8-7.5% of aluminum, 1.55-1.95% of iron, 0.11-0.15% of silicon. Thus, the golf club head alloy according to the present invention has a lower density due to the composition ratio thereof and, thus, can be used to produce a light golf club head, which is the effect of the present invention.
  • the golf club head alloy has an aluminum equivalent of 7.5-9.2.
  • the rolling rate of the golf club head alloy is enhanced, and the sheet formation rate in the subsequent procedures is increased.
  • a method of using the above golf club head alloy to produce a light golf club head according to the present invention includes: providing a sheet blank produced from the above aluminum club head alloy; annealing the sheet blank at 500-800° C. for 30-90 minutes and forming a striking plate; coupling the striking plate to a club head body to form a club head semi-product; and performing aging heat treatment on the club head semi-product at 400-700° C. for 30-240 minutes.
  • the weight of the resultant golf club head is reduced.
  • the cannon shot durability is further enhanced while reducing the bending deformations of the striking face in the horizontal direction (bulge) and the vertical direction (roll) after the cannon shot test, which are the effects of the present invention.
  • the striking plate has a tensile strength higher than 170 ksi, a yield strength higher than 150 ksi, an elongation of more than 10%, and a hardness of HRC 33-39.
  • the sheet blank is annealed at 650-800° C. for 40-50 minutes, and the aging heat treatment is performed on the club head semi-product at 550-650° C. for 30-120 minutes.
  • the FIGURE shows a method of producing a light golf club head of an embodiment according to the present invention.
  • a golf club head alloy according to the present invention includes by weight percent 6.5-7.5% of aluminum, 1.0-2.5% of iron, 0.05-0.2% of silicon, less than 0.15% of oxygen, less than 0.1% of carbon, less than 0.05% of nitrogen, the rest being titanium and inevitable impurities.
  • the golf club head alloy includes by weight percent 6.8-7.5% of aluminum, 1.55-1.95% of iron, 0.11-0.15% of silicon.
  • the golf club head alloy has a density of 4.35-4.39 g/cm 3 .
  • the golf club head alloy according to the present invention can have a lower density by adjusting the composition ratio thereof.
  • a manufacturer can use the above golf club head alloy to produce a light golf club head.
  • a method of producing a golf club head according to the present invention includes a sheet blank formation step S 1 , an annealing step S 2 , a club head semi-product formation step S 3 , and an aging heat treatment step S 4 , as shown in the FIGURE.
  • the sheet blank is produced from the above golf club head alloy.
  • the manufacturer can press the golf club head alloy into an electrode ingot, which is then smeltered into a titanium alloy rod. Then, the titanium alloy rod is forged into a plate blank that is finally hot rolled into the sheet blank.
  • the sheet blank is annealed at 500-800° C. for 30-90 minutes and forms a striking plate.
  • the sheet blank is annealed at 650-800° C. for 40-50 minutes.
  • the annealing temperature should not exceed 800° C. during the annealing step S 2 in order to avoid excessive softening that would lead to excessively large crystalline grains, thereby avoiding reduction in the tensile strength of the sheet blank.
  • the striking plate has a tensile strength higher than 170 ksi, a yield strength higher than 150 ksi, an elongation of more than 10%, and a hardness of HRC 33-39.
  • the manufacturer couples the striking plate to a club head body to form a club head semi-product.
  • the striking plate can be coupled to the club head body by welding, which can be appreciated by one having ordinary skill in the art. Redundant description is therefore not required.
  • the aging heat treatment is performed on the club head semi-product at 400-700° C. for 30-240 minutes.
  • the aging heat treatment is performed on the club head semi-product at 550-650° C. for 30-120 minutes.
  • the golf club head can be obtained accordingly.
  • striking plates (group A 1 ) are obtained by annealing at 780° C. for 45 minutes and are tested for measuring mechanical properties.
  • striking plates (group A 0 ) are produced from the conventional golf club alloy (64-Ti) by the same procedures. The results are shown in Table 1.
  • the density of the golf club head alloy according to the present invention (group A 1 ) is lower than the density of the conventional golf club head alloy (group A 0 ) and, thus, can be used to produce a lighter golf club head. Furthermore, the tensile strength of the golf club head alloy according to the present invention is slightly larger than the density of the conventional golf club head alloy.
  • golf club heads (group B 1 ) produced from the golf club head alloy by the sheet blank formation step S 1 , the annealing step S 2 , the club head semi-product formation step S 3 , and the aging heat treatment step S 4 are compared with golf club heads (group B 0 ) produced from conventional golf club alloy (64-Ti) by the same procedures, and the results are shown in Table 2.
  • the golf club heads (group B 1 ) produced from the golf club head alloy according to the present invention can withstand more cannon shots and, thus, have a better cannon shot durability.
  • the striking plates of the golf club heads produced from the golf club head alloy according to the present invention can be reduced in thickness to thereby reduce the weight of the golf club heads by about 3-4 g.
  • golf club heads (group C 1 ) produced from the golf club head alloy by the sheet blank formation step S 1 , the annealing step S 2 , the club head semi-product formation step S 3 , and the aging heat treatment step S 4 are compared with golf club heads (group C 0 ) produced without the aging heat treatment step S 4 , and the results are shown in Table 3.
  • the aging heat treatment step S 4 effectively increases the cannon shot durability of the golf club heads. After many times of cannon shots, the bending deformations of the striking face in the horizontal direction (bulge) and the vertical direction (roll) are significantly reduced (smaller than 30 mm).
  • the golf club head alloy according to the present invention has a density of 4.35-4.39 g/cm 3 due to the composition ratio thereof and, thus, can be used to produce a light golf club head, which is the effect of the present invention.
  • the method of producing a golf club head according to the present invention uses the above golf club head alloy. Under the premise of maintaining a proper cannon shot durability, the weight of the resultant golf club head is reduced. Furthermore, by performing the aging heat treatment on the club head semi-product, the cannon shot durability of the golf club head is further enhanced, and the bending deformations of the striking face in the horizontal direction (bulge) and the vertical direction (roll) are reduced, which are the effects of the present invention.
