Why Is Titanium Not Expensive, But Titanium Products (like Frames) Are?

There are several reasons for this situation:
1. Titanium sponge must be remelted in an electric furnace to become a usable ingot, and titanium is very reactive at high temperatures, making processing difficult;
2. Pure titanium is very soft and generally not suitable for use as titanium products, so other elements need to be re-added. For example, titanium 64, which is commonly used in the aerospace industry, has many other elements added to improve the performance of the metal.
3. Titanium is very hard to work with. It's not really hard, but it is "sticky". I picked up a Titanium 64 handle with a spatula and soon the texture of the spatula was filled with slag. It is said that due to low speed, titanium can not cut, too high speed, titanium will oxidize, ordinary machining centers can not process titanium products.

4, titanium using glasses is even more difficult. The rim of the frame is very fine and requires a lot of fine processing. This is definitely a big challenge for titanium, a particularly difficult material to work with. In addition, titanium frames also involve titanium welding technology, which is more difficult. How difficult is titanium alloy processing technology? Let's put it this way, people all over the world who design airplanes, as long as they can use aluminum alloys through structural optimization, they won't use titanium alloys because of the difficulty of machining titanium alloys. How hard is titanium alloy welding metal? Titanium alloy welding technology is currently only China, the United States, Russia can be used in the aircraft. Russia's titanium alloy welding technology is good, titanium ore is also a lot, so the use of titanium alloy made several submarines, the maximum depth of more than 1,000 meters, in the world has been unparalleled.
