Titanium and titanium materials have a series of comparative advantages over other metal materials and are one of the important strategic metal materials in the country. Titanium is silver white, melting point up to 1668℃, belongs to refractory rare light metal. Titanium has the characteristics of low density, high specific strength, low thermal conductivity, good resistance to high temperature and low temperature, strong corrosion resistance, good biocompatibility, etc., which is far superior to other alloys in high-end fields such as aerospace applications. Specifically, the same tensile and fatigue strength, titanium alloy can reduce the weight of aviation equipment, can replace steel; Titanium alloy can be used in a relatively high temperature environment, can replace aluminum alloy, etc. Titanium alloy has stable chemical properties, good corrosion resistance, and can replace aluminum alloy parts. Titanium alloy and polymer matrix composites have good compatibility.
Titanium metal and its products are widely used in aviation, aerospace, ships, weapons, biomedicine, chemical metallurgy, ocean engineering, sports and leisure and other fields for its superior performance. Titanium alloy is an alloy formed by adding appropriate amount of other elements on the basis of titanium, adjusting matrix phase composition and comprehensive physical and chemical properties. According to the prospectus, titanium is known as "space metal," "ocean metal," "modern metal" and "strategic metal." Titanium and titanium alloy are of strategic significance to the development of national defense, economy and science and technology. The development level of titanium industry is an important symbol of a country's comprehensive strength.
Each link of the titanium alloy industry chain presents a pattern of concentration at both ends and slightly scattered in the middle. The upstream of the industrial chain is the sponge titanium supplier, which occupies the location advantage of natural resources and presents a certain natural monopoly. The process barriers in the middle and upstream titanium alloy industry are high, and it takes as long as several years for material enterprises to become qualified suppliers, which is superimposed with higher production capacity and cost control ability requirements. At present, major domestic enterprises have formed the first-mover advantage. The midstream forging and casting industry, especially the large die forging manufacturers, has high requirements on the input of large equipment. With the combination of technical barriers such as the unpredictability of heat treatment in midstream process, enterprises with first-mover advantages can achieve scale utility by improving capacity utilization rate and have a large elasticity space of profitability. Due to various types of structural parts and different process requirements, the scale of personnel and equipment investment must be expanded to expand production, and the scale effect is relatively limited.
