Titanium Road Bike----the Choice Of Smart People
Titanium alloy road bike----the choice of smart people
Like to ride a road bike, we know that the current mainstream frame material is just a few kinds of titanium alloy road bikes - the road car with the choice of fever, steel frame (low price to high price is also available) aluminum alloy (low price) There are high-priced places, more famous are the giant TCR SLR series, Canon Dell CAAD series, lightning top aluminum, and TREK's top aluminum, etc.) carbon fiber (many of the entry whites feel that the frame is carbon fiber definitely It is relatively expensive. I don’t know that the so-called Xiamen carbon in China can buy carbon fiber frames for more than 1,000 yuan. Of course, the quality problem is a matter of opinion. No comment, anyway, domestic manufacturers always like to boast carbon fiber modulus.
Titanium material, this is the article to be introduced in this article. Many people say that it is a fever-reducing choice. There are also many people who don’t understand why it is a fever-reducing choice. Of course, this is not related to people’s understanding of titanium alloy. Relationship.
Titanium alloy introduction
Titanium is an important structural metal developed in the 1950s. Titanium alloys are widely used in various fields due to their high strength, good corrosion resistance and high heat resistance. Many countries in the world have recognized the importance of titanium alloy materials, which have been researched and developed successively and have been put into practical use. In the 1950s and 1960s, the company developed high-temperature titanium alloys for aircraft engines and structural titanium alloys for the aircraft. In the 1970s, a number of corrosion-resistant titanium alloys were developed. Since the 1980s, corrosion-resistant titanium alloys and high-strength titanium alloys have been further developed. development of. Titanium alloys are mainly used to make aircraft engine compressor components, followed by structural components for rockets, missiles and high-speed aircraft.
Frame material comparison
Steel frame: The advantage of the steel frame is that it can be made very slender and maintains strength, but the weight and elasticity are not good, and once the surface paint is dropped, corrosion resistance is a problem. There are many kinds of steel frame pipes. What is the higher-end pigeon? Steel, Renault 925 and the like, the general Taobao car is high carbon steel.
Aluminum frame: The strength of aluminum alloy is not as good as steel, so it can't be too thin, there is a "tube type", but the elasticity is good, the force is much harder than the steel frame, sometimes it will feel the back, on the Canon Dell CAAD10 There is a good embodiment, the feeling of stepping is very strong, but metal fatigue is a problem, after a few years of use, the performance is slightly reduced, the mainstream materials are 6061, 7005, 7075 and so on.
Carbon frame: Carbon is very simple, the most "soft", the most flexible, it can be said that the most fearful collision, but the lightest, so the "carbon shelf life" has been a topic, but the carbon fiber force is the most in all frames Ok, that is, the road feel is very direct, there is a certain shock absorption, that is, the feeling of feedback is the most accurate, especially in climbing and sprinting. This feeling is very direct, the carbon fiber frame market is really The fish and dragon are mixed, the price is too chaotic, but it is gratifying that the products of some foundries in China are still good, cheap and good, the mainstream material is Toray's T700 T800.
Titanium: The titanium alloy is also seen in front of it. It is a long life with a frame. The durable titanium alloy road bike is a road car with a fever-reducing choice. The long-distance is very comfortable. The metal properties determine the shock absorption is very good. Titanium alloy It has a good anti-fatigue property. It is called a memory metal. It is lighter than steel. It is slightly heavier than aluminum. Its strength is far more than that of the two metals. Therefore, it is very suitable as a material for the frame, but it also has a shortcoming. Most of the round tubes, the top has a special-shaped tube, but the cost is slightly expensive, and it is not as easy to paint as other materials in the frame painting. Most of the titanium is natural. Some top titanium frames are similarly painted with paint. The mainstream material is 325ti. And 64ti.
Why is titanium bike is expensive?
Some friends asked me, I went to Baidu for a titanium alloy frame, and I also looked at Taobao. The price is still relatively expensive. Why is it so expensive? Because the nature of titanium alloy determines the welding difficulty of titanium alloy frame, it must be insulated under the protective gas, and the process requirements are very strict. Secondly, the quality problem of titanium alloy pipe is also a big problem. A batch of pipes in the alloy factory had quality problems, which caused the frame to break from the head pipe. Fortunately, there was no serious problem.
Titanium road bike tubes
Basically, there are two major categories, 325 titanium and 64 titanium. The grades are different and the performance is different. 6/4 titanium is very hard, even hard to some brittleness, 325 titanium is relatively tougher, some people psychologically feel that 64 titanium is the top of the titanium alloy frame, in fact, I also have this feeling, of course, still have to look The wall thickness, the tube type and many other factors are combined. One yield strength is 1100 and 950. The Young's modulus is the same. The wall thickness is high and the rigidity is low. The 6al4v is harder than the 3al2.5v. It’s all thighs that fool you.
