Application and prospect of titanium - part 1

At present, the demand for titanium products in the military aviation industry accounts for 15% of the total demand for titanium products in the world, and it is likely to grow to 20-25% in 2-3 years. However, some experts believe that even if this happens, the growth and decline of the civil aviation industry and the military aviation industry cannot really increase the actual demand for titanium products in the aviation industry. However, the expectation of the long-term development prospect of the world aviation industry is encouraging. The president of rbUS Industries firmly believes that the number of passenger aircraft owned by the world civil aviation industry will increase from 10,000 to 19,000 by 2019. This means that even if the world titanium industry does not grow, it will not be lower than the current production level.

Application of titanium

According to statistics, at present, about 10% of the world's titanium metal consumption is used to manufacture high gear pushchairs, computer shells and jewelry. At the annual meeting of the International Titanium Industry Association held not long ago, representatives said many times that the prospect of titanium metal application in the world jewelry industry is very bright, and efforts should be made to increase the consumption of titanium metal in this industry. According to the opinion of Edward Rosenberg, President of Sp Corp of the United States, although international jewelry manufacturers are still conservative on the whole, they have begun to study and compare the advantages and disadvantages of titanium metal and precious metals such as platinum, gold and silver in jewelry manufacturing in recent years. Edward Rosenberg believes that from the perspective of development, the international jewelry industry will not only consume 10% of titanium products in the future, but 35%, or even 45%. However, the precondition for attracting users from other non-traditional fields to adopt titanium products on a large scale is that the cost of titanium products must be reduced, which of course takes time. However, in any case, a considerable part of titanium products will always belong to the aviation industry, although titanium products will be more and more widely used in other industries and people's daily life

In life, but so far, titanium metal production enterprises still have to keep their eyes on the sky.

Since 1957, titanium materials have been widely used in space navigation, mainly as rocket engine casings, artificial satellite casings, fasteners, fuel storage tanks, pressure vessels, etc; There are also the cabin, skeleton, inner and outer skin of the spaceship. In space navigation, the use of titanium can greatly reduce the weight of aircraft. From the perspective of economic effect, the reduction of structural weight can save a lot of fuel, and greatly reduce the cost of building and launching rockets and missiles.

At present, titanium has replaced graphite in electrolytic cells at home and abroad. At present, some foreign countries have stipulated that all titanium condensers must be used in atomic power plants for safety. In this respect, titanium consumption is considerable. For example, thermal power plants with power generation capacity of 600000 KW require 60t of titanium materials, while atomic power plants with power generation capacity of 110KW require 150t of titanium materials.

Adding a small amount of titanium in alloy steel can greatly improve the properties of steel, and improve the strength, toughness and corrosion resistance of steel. In the hydrometallurgy of non-ferrous metals, good results have also been achieved after the use of titanium. For example, in the electrolytic production of metal nickel, titanium plate has been used as the parent plate instead of stainless steel plate. The stainless steel plate can only be used for about one year, while the titanium plate can be used for more than 10 years, and the service life has been extended by 10 times.  

Superconducting material is a promising material in the future. The alloy made of about 50% titanium and 50% niobium is one of the most researched and used superconducting materials at present. Niobium titanium alloy accounts for 90% of the more than 100 tons of superconducting materials produced annually in the United States. The artificially made barium titanate (BaTiO3) has special properties. It has a high dielectric constant and the capacitor made of it has a large capacity. At present, although titanium is 2-3 times more expensive than stainless steel, its service life is generally 10 times longer than stainless steel.
