Titanium is mainly used for the production of aircraft engine compressor

Titanium is mainly used for the production of aircraft engine compressor components, followed by structure rockets, missiles and high-speed aircraft. The mid-1960s, titanium bars and its alloys have been in general industrial applications, electrodes for electrolysis industry production, power plant condensers, oil refining and desalination heater and environmental pollution control devices. Titanium and its alloys have become a corrosion resistant structural materials. In addition, for the production of hydrogen storage materials and shape memory alloys.
Titanium is an important new structural materials used in the aerospace industry, the proportion between the aluminum and steel, the strength and the use of temperature between, but higher than aluminum, steel strength and excellent corrosion resistance to sea water and ultra-low temperature performance. In 1950 the United States for the first time in the F-84 fighter-bombers later used as the fuselage insulation panels, wind shield, tail cover other non-load-bearing components. 1960s began using parts from titanium alloy fuselage toward the rear of the fuselage, in part, instead of structural steel bulkheads, beams, flap tracks and other important bearing components. The amount of titanium in military aircraft rapidly increased, reaching 20% to 25% by weight of the aircraft structure. Since the 1970s, civilian aircraft began extensive use of titanium alloys, such as the Boeing 747 with a capacity of 3640 kg or more of titanium. Aircraft Mach number greater than 2.5 was used in place of titanium casting to the steel, to reduce the structural weight. Again, American SR-71 high-altitude reconnaissance aircraft speed (Mach 3, altitude 26,212 meters), 93% titanium structural weight of the aircraft, known as "all-titanium" aircraft.

Introduction What are the characteristics of titanium?

Introduction What are the characteristics of titanium?
Titanium used in petroleum, chemical, pharmaceutical, food industry, has a pivotal role. titanium bars and titanium alloys can be long-term work between 450 ℃ ~ 550 ℃ and minus 250 ℃. Titanium has good salt tolerance classes, the ability to seawater and nitric acid corrosion, Ti-30M alloy is resistant to high concentrations of hydrochloric acid and sulfuric acid corrosion.
Titanium for pitting, etching, stress corrosion resistance is particularly strong; alkali, chloride, chlorine, organic materials, nitric acid, sulfuric acid, etc. have excellent corrosion resistance. However, the corrosion resistance of titanium with a reduction of oxygen and chromium salts medium is poor. Here Xiaobian to introduce titanium characteristics.
Titanium plate is kind of the equivalent of the surface oxide film with a good durable wear hair separating agent, using titanium plate plates save seed separating agent, make peeling easier plate, eliminating the pre-treatment process kinds of plates, titanium plates than seed copper starting sheet to light half titanium starting sheet is more than three times the life of the copper seed plate, depending on the operating conditions of up to 10 to 20 years. Titanium plate preparation seed crystal structure of copper dense, smooth surface, good quality. Because titanium species sheet without smearing separating agent, and thus avoid the contamination of copper electrolyte.Increase productivity reduce copper production costs, which have better economic benefits.

Chemical classification of titanium

Chemical classification of titanium
Titanium is allotrope, melting point 1668 ℃, showed a close-packed hexagonal lattice structure, called α titanium bars at temperatures below 882 ℃; body-centered cubic lattice structure at above 882 ℃ was called β titanium. The use of the different characteristics of the two titanium structures, adding appropriate alloying elements, so that the phase transition temperature and relative content of different tissues obtained by gradually changing the titanium (titanium alloys). At room temperature, there are three titanium matrix organization, titanium will be divided into the following three categories: α alloy, (α + β) alloys and β alloys.
