Grade 5 titanium alloy rods have the advantages of high strength, low density, good mechanical properties, good toughness and corrosion resistance. In addition, titanium alloy rods have poor technological performance, difficult cutting, easy to absorb impurities such as hydrogen, oxygen, nitrogen, carbon, etc. during hot processing, poor wear resistance, and complex production process. Industrial production of titanium began in 1948. In order to meet the needs of the development of the aviation industry, the titanium industry is developing at an average annual rate of about 8%. At present, the annual output of materials processed by all titanium alloy rod manufacturers has reached more than 40,000 tons, and there are nearly 30 titanium alloy rod brands. The widely used titanium alloy rods are Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) and industrial pure titanium (TA1, TA2 and TA3).
(1) Titanium alloy rod has high strength
The density of titanium alloy can be analyzed generally at about 4.5g/cm3, which is only 60% of steel. The strength of pure titanium is close to the strength of ordinary steel in our company. Some problems have high strength and titanium alloys have surpassed the development of many related researches. The strength of alloy structural steel. Therefore, the specific strength (strength/density) of titanium alloy is much higher than that of other metal industrial structural design materials, which can produce parts with high working strength, good rigidity and light weight. At present, traditional Chinese titanium alloys are used in the engine work of my country's aircraft mainly through components, skeletons, skins, fasteners and landing gear.
(2) Titanium alloy rod has high thermal strength
The operating temperature is several hundred degrees higher than that of aluminum alloy, and the required strength can be maintained at medium temperature. It can work for a long time at 450-500 ° c, and the specific strength is still high in the range of 150-500 ° c. The specific strength of aluminum alloy is 150 °C drop, the working temperature of titanium alloy can reach 500 °C, and the working temperature of aluminum alloy is below 200 °C.
(3) Titanium alloy rod has good corrosion resistance
The corrosion resistance of titanium alloys in humid atmosphere and seawater is significantly better than that of stainless steel, and it has good corrosion resistance such as alkali, chlorine, chlorine, nitric acid, and sulfuric acid. However, titanium has poor corrosion resistance to reduced oxygen and chromate media.
(4) Titanium alloy rod has good low temperature performance
The mechanical properties of titanium alloys can be maintained at low and ultra-low temperatures. Titanium alloys with good low temperature performance and extremely low gap design elements, such as TA7, can maintain a certain plasticity by themselves at -253 °C. Therefore, the development of titanium alloys is also an important low-temperature product structure. material.
