Titanium metal production has been only half a century old since 1948. It is a new industry that has developed along with the aerospace and aerospace industries. Its development has undergone several ups and downs because titanium is related to aircraft manufacturing. But on the whole, the development of titanium is very fast, and it exceeds the development speed of any other non-ferrous metals. This can be seen from the development of titanium sponge industry in the world: The titanium sponge production scale is 60kt/a in the 1960s, 1lOkt/a in the 1970s, 130kt/a in the 1980s, and 140kt/a by 1992. The actual production reached the highest level in history in 1990 and it was 105kt/a.
