Titanium is a kind of metal. In China, the output of titanium is very high and it can be seen everywhere. However, titanium is also very rare and can only be seen in the organization bases of various places. Titanium is the material people use to create rockets. Using this titanium to create rockets can ensure that the rockets fly higher and farther, so that the safety factor of the rocket is also higher. Titanium is also a cosmic metal, so what are the effects of titanium? It was not until 1947 that people began to smelt titanium in factories. That year, the output was only 2 tons. In 1955, production surged to 20,000 tons. In 1972, annual production reached 200,000 tons. The hardness of titanium is similar to that of steel, but its weight is almost half of the same volume of steel. Although titanium is slightly heavier than aluminum, its hardness is twice that of aluminum. Nowadays, titanium is used extensively to replace steel in space rockets and missiles. According to statistics, the amount of titanium used for space travel in the world now exceeds one thousand tons per year. Extremely fine titanium powder is also a good fuel for rockets, so titanium is known as cosmic metal and space metal. Titanium has good heat resistance and its melting point is as high as 1725℃. At room temperature, titanium can remain safe and sound in various strong acid and alkali solutions. Even the most powerful acid, aqua regia, cannot corrode it. Titanium is not afraid of seawater. Someone once sank a piece of titanium to the bottom of the sea. When they took it out five years later, they found many small animals and underwater plants stuck on it, but it was not rusted at all and was still shiny. Now, people are beginning to use titanium to build submarines - titanium submarines. Because titanium is very strong and can withstand very high pressures, this submarine can travel in the sea as deep as 4,500 meters. Titanium is corrosion-resistant, so it is often used in the chemical industry. In the past, components in chemical reactors that contain hot nitric acid were made of stainless steel. Stainless steel is also afraid of the strong corrosive agent - hot nitric acid. Every six months, these parts must be replaced. Now, although the cost of making these parts with titanium is more expensive than stainless steel parts, it can be used continuously for five years, which is much more cost-effective. We have introduced the effects of titanium in detail above. Titanium has a lot of utilization value in daily life. It can be used to make many tools. This kind of titanium is also very heat-resistant. Titanium will not corrode and rot after many years. Titanium is also used to make decorations. However, people generally use this titanium to make high-tech materials, which adds utilization value to the country. |
