Golf is largely affected by the materials of the golf equipment. Therefore, different clubs are required to be used in different places and situations on the golf course. The clubs are also designed into a variety of shapes of different lengths, which can be roughly divided into three categories. : Wood, iron and putter.
1. Titanium alloy wood club head
Wood rods are used for opening and long-distance shots. In order to make the ball hit more straight and farther, the weight of the wood head needs to be maintained at 200g, and the volume should be increased as much as possible to increase the ball and wood head. Contact area.
Titanium alloy has low density, high strength and good corrosion resistance. Under the same weight, the hollow ball head made of titanium alloy is 2-3 times larger than the stainless steel ball head, and the mass can be evenly distributed around the ball head, so that the player can hit the ball farther and straighter.
2. Titanium alloy iron head
Irons are mainly used for mid-range and precise shots, which require higher accuracy. When the ball is in contact with the striking surface, the striking surface must provide enough friction to increase the spin rate after the ball is hit. In this way, the rolling of the ball can be better controlled when hitting the ball, making the hitting more accurate.
Some companies add a titanium-diamond composite to the club’s striking surface to increase the coefficient of friction through diamond particles on and near the surface of the striking surface. But this will make the ball head overweight by nearly 30g, otherwise, the ball head will become smaller and even difficult to hit the ball. The iron head using titanium alloy as the body can be embedded with diamond composite on the same volume of the striking surface, while the quality remains unchanged.
3. Titanium alloy putter head
Putting is used to hit the ball into the hole on the green [i]. The titanium-tungsten putter series launched by a company uses titanium alloy in the middle body of the ball head, with counterweight tungsten at both ends [ii]. After the tungsten block is inlaid with the body, it can be made to reach Dense combination.
The density of titanium alloy is generally 4.51g/cm, and the density of weight tungsten is about 19g/cm so that 70% of the mass of the ball head is concentrated at the two ends. This design can increase the rotational inertia of the ball hitting surface by about 50%. The higher the rotational inertia, the putter head can prevent the twisting caused by not hitting the center of the ball head. This putter has more obvious advantages on the green than the traditional putter.
market expectation
With the rapid growth of China's economy and the rapid improvement of people's living standards, golf has been favored by the majority of sports enthusiasts. Especially for middle and high-level consumer groups, golf is also a way of business social interaction in addition to physical fitness. China will become another consumer market with huge potential besides the United States and Japan.
Titanium alloys have entered the golf equipment industry for more than 20 years, and various titanium materials have been used in golf heads in a comprehensive manner. But the price of titanium alloy ball heads is higher, almost three times that of stainless steel ball heads, so the ball head market is still dominated by stainless steel. How to improve titanium alloy casting technology and reduce costs will become the main research direction of golf head manufacturers in the future.
