Why titanium bike frame's retail price is so expensive, compared with steel and carbon?
I believe that contact with bicycles knows the material "titanium alloy". Titanium alloy is an alloy composed of other elements based on titanium. It can be said that it is the best in bicycle materials. It is not only expensive but also has good quality and material quality. Titanium alloy materials are more precious than us. The carbon fiber parts are much more expensive.
Titanium alloy is widely used in bicycles. It is not only used in titanium alloys on the frame. Basic parts of titanium bicycles are basically made of titanium alloy parts, such as titanium alloy stems, titanium alloys, etc. There are titanium alloy materials, even the screws of bicycles will have titanium alloy materials. Titanium alloys can be said to belong to super high-end metal materials, and the processing technology is extremely complicated.
Titanium alloy parts, firstly with screws, titanium alloy screws are incomparable with respect to steel screws, regardless of the texture or quality of the screws. Titanium alloy screws have lightweight, high strength, and good toughness. Corrosion resistance, etc. It can be said that all titanium alloy parts have the characteristics of lightweight, high strength, good toughness, and corrosion resistance. The disadvantage is that it is particularly expensive.
Titanium alloys are so expensive because titanium alloys are high-performance materials that are widely used in aerospace technology. The manufacturing process is complicated and the quantity is not so much. It is the most expensive material for manufacturing bicycle frames. It is one of the best in all metal materials, so it is very popular among bicycle lovers. Although it is expensive, it is worth the money. These are the reasons why titanium alloy is expensive.
In so many bicycle materials, such as steel, aluminum alloy, carbon fiber, etc., only titanium alloy has high strength, low density, low modulus of elasticity, excellent fatigue resistance and corrosion resistance. Carbon fiber material bicycles, carbon fiber parts are expensive, but a fatal flaw is not repairable.
Titanium alloy can be said to have inherent advantages in repairing this aspect. Once the carbon fiber is damaged, it is irreparable. Although it is only a little crack, titanium alloy is not like this. If the titanium alloy is damaged, it will only malfunction in the welding place. As long as it is re-welded, it can be used continuously. The frame of materials like aluminum alloy is completely repaired with titanium alloy.
At this time, you may have questions about why aluminum alloys can't be repaired if they break. It's not that they can't be repaired. Everyone knows what bicycles are pursuing and they are lightweight. Therefore, when bicycle manufacturers use aluminum alloy materials, Light weight will be thought of, so the aluminum alloy used will be thinner, and the thickness of the frame will not provide the conditions for welding.
Not all aluminum alloy frames can't be repaired, but they are not as high as titanium alloys. Titanium bicycles are extremely difficult to be broken because of their high strength. Even if they fall, they are generally In the welded part, it can continue to be used after the repair welding, and the strength change is not too large, so this is also the reason why the titanium alloy is expensive.
With the continuous innovation of bicycle technology, the demand for titanium alloy is getting bigger and bigger. Xiaobian believes that most of the bicycle materials in the future will be titanium alloy, and the development speed of titanium alloy is getting faster and faster.
