Application cases of titanium alloy materials such as titanium forgings, titanium alloy tubes, titan

According to statistics, 16%-20% of the total amount of titanium is used in sports and leisure products, and it is the third largest user of titanium. In sports equipment, titanium is used in: golf clubs, heads, tennis rackets, badminton rackets, fencing protection Masks, swords, sprinting shoe spikes, climbing tools, snowboards, ski shoes, ski poles, ice skates, diving suits, fishing tackle, tent poles, etc. The following are typical application cases of titanium and titanium alloys in leisure sports.

　　1, golf club, ball head

　　 Titanium golf clubs and heads are still the main pillars of titanium used in civil applications. It seems that every manufacturer in the world has produced golf clubs and heads. Golfers always want to play with clubs with bigger heads. Titanium has a small specific gravity and high strength, which can make the ball head larger without increasing the total weight of the club. In extensive tests, the hit rate of golfers with titanium heads can be increased by an average of 20% compared with the hit rate of steel heads, and the hitting distance has been improved. Larger golf heads currently require a very thin surface, so the surface material needs to be very durable. The SP-700 new titanium alloy developed by Japan Steel Pipe Company has high strength and good formability. Recently, it has been used as the surface material of Taylor brand 300 series golf heads and is popular in the golf market.

　　2, tennis racket, badminton racket

　　 At present, the application of titanium in tennis rackets is mainly to bury a net made of pure titanium into the racket frame. In this way, not only the momentary inertia force of the tennis racket hitting the ball is improved, but even when the ball does not hit the center of the racket, the ball is easily shot out, which enhances the hitting power of the racket, and is highly praised by users. In recent years, the demand for titanium tennis rackets in Japan has been on the rise. Now, almost all tennis racket manufacturers in Japan are selling titanium rackets, which account for about half of the racket market. In order to classify the grades, while producing rackets according to the characteristics of titanium, the handles of tennis rackets also use titanium-nickel superelastic alloy materials and coating processing methods to develop new uses for titanium. Recently, the use of titanium's resilience to enhance the hitting effect has attracted much attention. Some Japanese companies are currently developing and applying new titanium fiber materials to tennis rackets. This alloy is a shape memory alloy with super-elastic function. Even if it deforms under load, it will return to its original shape immediately after the external force is removed. Baosheng Metal embeds this material on the left and right sides of the racket handle, which can significantly increase the rebound force when hitting the ball. Like tennis rackets, badminton rackets made of pure titanium for the frame and titanium alloy (Ti-3Al-2.5V) for long handles have been developed and commercialized.

　　 3. Racing bicycles

　　 The bicycle is driven by human power because it needs to be very light, especially on a racing car that considers the speed of the race. If the weight of the car is reduced by 1 gram, it can gain a thousandth of a second. Normal bicycles use 36 spokes, while titanium bicycles use 24, which not only reduces weight, but also reduces wind resistance. Titanium and titanium alloys are first used in parts. The Italian company Campagnolo has used titanium and titanium alloys to manufacture a variety of parts for racing bicycles, including: encapsulated transmission pins, left-hand nuts, pinless crankshafts, Front and rear hub axles, left and right pedal axles, etc. The American Litespeed company uses titanium to produce bicycle frames. The average weight of these frames is 2.5 pounds, and each is priced at $2,800. Titanium frames are lighter and more comfortable than chromium-molybdenum alloy frames, and have a longer lifespan. In the past 4 years, frames made of Ti-3Al-2.5V (sports grade) titanium alloys made of industrial pure titanium tubes for non-aviation are very popular. The price of each pair is between US$1600-3500, and the price of the entire bicycle It is US$2400-6000. There are currently nearly 50 companies producing titanium bicycles, and the United States has long been the largest producer and consumer of titanium bicycles. Baosheng Metal is now widely developing bicycle sports all over the world. Titanium bicycles are particularly suitable for high-end bicycle sports. Therefore, the sales of titanium bicycles are gradually increasing.

　　 4. Racing cars

　　 Because titanium has excellent physical and mechanical properties, it has been used in racing cars and limited-production exotic sports cars. The application of titanium in the automobile industry can greatly reduce the weight of automobiles, reduce their fuel consumption, protect the environment and reduce noise. The characteristics of titanium have been well reflected in racing cars. Almost all metal parts in the car can be made of titanium and titanium alloys, such as: bolts, connecting rods, rockers, buffer rear brackets, exhaust pipes, return pipes, valves, valve springs, brakes, sensor components, etc. In addition, titanium can also be used for surface coating, and has been used to improve the surface performance of brake plates, which can ensure that the brake plates are light and have a long life. Titanium is used in automobiles to extend the service life of valves, springs and connecting rods.

　　 5. Other sporting goods

　　Mountaineering and ski equipment is moving in the direction of lightweight and miniaturization. Titanium has the characteristics of light specific gravity, high strength, and low impact value at low temperatures. As an excellent material for mountaineering and skiing equipment, it has been widely used, such as titanium alloy mountaineering sticks, mountaineering sole nails, climbing fasteners, and ski poles , Ice skates, etc. Titanium sporting goods also include: fencing protective masks, swords, fishing rods, fishing reels, racing boat parts, and injection molded Ti-Fe series sole nails for track and field shoes. At present, titanium used in sporting goods in my country is still in its infancy, and the technology and technology still lag far behind the advanced level of foreign countries, and the production equipment is still relatively backward. At the same time, it also shows that my country has great growth potential in this area.
