First, how about titanium alloy tube

1. The density of titanium alloy is generally about 4.51g / cm3, which is only 60% of steel. The density of pure titanium is close to that of ordinary steel. Some high-strength titanium alloys exceed the strength of many alloy structural steels. Therefore, the specific strength (strength / density) of the titanium alloy is much greater than that of other metal structural materials, and the manufactured parts have high strength, good rigidity, and light weight.

2. 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 the temperature of 450 ~ 500 ℃. High specific strength, while the specific strength of aluminum alloys decreases significantly at 150 ° C. The working temperature of titanium alloy can reach 500 ℃, while that of aluminum alloy is below 200 ℃.

3. Titanium alloy With its excellent characteristics, titanium alloy has gradually become one of the new important structural materials in the development of the aerospace industry. Titanium alloy is between aluminum and steel in terms of specific gravity strength and temperature range, but the titanium alloy itself has more superior characteristics, that is, it has a higher specific strength, and, Has good resistance to seawater corrosion and ultra-low temperature performance.

4. Titanium alloy can maintain its mechanical properties at low and ultra-low temperatures. Low temperature properties, titanium alloys with very low interstitial elements, such as TA7, can still maintain a certain degree of plasticity at -253 ° C. Therefore, titanium alloy is also an important low temperature structural material.

What is the use of titanium alloy tube

Second, the use of titanium alloy pipe

1. Titanium alloy is mainly used to make aircraft engine compressor parts, followed by rockets, missiles and high-speed aircraft structural parts. In the mid-1960s, titanium and its alloys have been used in general industry for making electrodes for the electrolytic industry, condensers for power stations, heaters for oil refining and desalination, and environmental pollution control devices. Titanium and its alloys have become a corrosion resistant structural material. It is also used in the production of hydrogen storage materials and shape memory alloys.

2. Titanium alloys can be divided into heat-resistant alloys, high-strength alloys, corrosion-resistant alloys (titanium-molybdenum, titanium-palladium alloys, etc.), low-temperature alloys, and special-function alloys (titanium-iron hydrogen storage materials and titanium-nickel memory alloys) )Wait. The composition and properties of typical alloys are shown in the table.
