Golf is an advanced sport. It often gives the impression that it is "upscale in the high-end atmosphere." It is loved by high-end people at home and abroad. People have high requirements for golf equipment, not only beautiful appearance, but also lightweight clubs, and fast and accurate shots, thus promoting the continuous development of the golf club manufacturing industry.

Most of the golf clubs used in the early days were made of persimmon wood, and later they were gradually replaced by stainless steel. In the early 1990s, the Japanese began to introduce titanium golf clubs. The use of titanium alloy clubs has excellent stability and elasticity, which makes the family of golfers an invaluable asset, thus greatly promoting the development of titanium golf clubs.

Golf is largely affected by the equipment of the golf club. Therefore, different clubs are required to be used in different situations at different locations on the course. The clubs are also designed to have a variety of different lengths and can be divided into three categories. : Wood, iron and putter.

1, titanium alloy wood head

Wooden clubs are used for driving and long-distance shots. In order to make the ball more straight and farther, the weight of the wooden club head needs to be maintained at 200g, and the volume must be increased as much as possible to increase the ball and wooden club 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 sufficient friction to increase the spin rate after the ball is hit. In this way, when the ball is hit, the ball can be better controlled to make the ball more accurate.

A company has added a titanium-diamond composite to the striking surface of the club to increase the coefficient of friction by using diamond particles on the surface and near surface of the striking surface. But this will make the ball head overweight nearly 30g, otherwise the ball head will become smaller and even harder to hit the ball. The iron head with titanium alloy as the body can be inlaid with diamond composite on the striking surface of the same volume, while the quality remains unchanged.

3.Titanium putter head

Putters are used to hit the ball into the hole on the green [i]. The titanium-tungsten putter series launched by a company uses a titanium alloy in the middle body of the ball head and counterweight tungsten [ii] at both ends. The tungsten block and the body are inlaid into each other by high pressure sintering or hot pressing to achieve Dense combination.

The density of hafnium titanium alloy is generally 4.51g / cm ?, and the density of weighted tungsten is about 19g / cm ?, so that 70% of the mass of the ball head is concentrated at both ends. This design can increase the inertia of the ball striking surface by about 50%. The higher the rotational inertia, the putter head can prevent the distortion caused by not hitting the center of the ball head. This putt has a clear advantage over traditional putts on the green.

  market expectation

With the rapid growth of China's economy and the rapid improvement of people's living standards, golf has been favored by sports enthusiasts. Especially for middle and high-end consumer groups, golf is not only a way to keep fit, it is also a way of business and social interaction. China will become another consumer market with huge potential besides the United States and Japan.

Titanium alloy has entered the golf equipment industry for more than 20 years, and the use of various titanium materials on golf heads has been very comprehensive. However, 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 mainly stainless steel. How to improve titanium alloy casting technology and reduce cost will become the main research direction of golf head manufacturers in the future.
