What are the properties of titanium alloy tubes?

1.The density of titanium alloys is generally around 4.51g per cubic centimeter, which is only 60% of that of steel. The density of pure titanium is close to that of ordinary steel, and some high-strength titanium alloys exceed the strength of many alloy structural steels. Therefore, the specific strength (strength/density) of titanium alloys is much greater than that of other metal structural materials, and the components made from them have high strength, good rigidity and light weight.

2. The operating temperature is several hundred degrees higher than that of aluminum alloys. They can still maintain the required strength at medium temperatures and can work for a long time at temperatures ranging from 450 to 500℃. These two types of titanium alloys still have a high specific strength within the range of 150℃ to 500℃, while the specific strength of aluminum alloys drops significantly at 150℃. The operating temperature of titanium alloy can reach 500℃, and that of aluminum alloy is below 200℃.

3. Due to its excellent properties, titanium alloy has gradually become one of the new and important structural materials frequently used in the development of the aerospace industry. Titanium alloy is superior to aluminum and steel in terms of specific gravity, tensile strength and operating temperature range. However, titanium alloy itself has more superior properties, such as high specific strength, excellent resistance to seawater corrosion and ultra-low temperature performance.

Titanium alloys can still maintain their mechanical properties at low and ultra-low temperatures. Titanium alloys with excellent low-temperature performance and extremely low interstitial elements, such as TA7, can still maintain certain plasticity at -253℃. Therefore, titanium alloy is also an important low-temperature structural material.
