There are many types of pipes and materials used in construction and decoration. Do you know how to choose the right one? Are you familiar with titanium alloy pipes and their uses? In this article, we will provide answers to these questions, hoping to help you.
The density of titanium alloy is generally around 4.51g/㎝³, only 60% of steel. Some high-strength titanium alloys have a strength greater than many alloy structural steels. Therefore, the titanium alloy has a much larger specific strength (strength/density) than other metal structural materials, making the produced parts strong, rigid, and lightweight.
Titanium alloy can maintain the required strength even at high temperatures. It can work for a long time at temperatures ranging from 450℃ to 500℃. In the temperature range of 150℃ to 500℃, titanium alloy still has a high specific strength, while the specific strength of aluminum alloy significantly drops at 150℃. The working temperature of titanium alloy can reach 500℃, while aluminum alloy is limited to below 200℃.
Titanium alloy, with its excellent properties, has gradually become one of the important structural materials in the aerospace industry, often used in the manufacture of aircraft engines, rockets, missiles, and high-speed aircraft parts. Titanium alloy has a higher specific strength than aluminum and steel, and also has better resistance to seawater corrosion and ultra-low temperature durability.
Even at low and ultra-low temperatures, titanium alloy can still maintain its mechanical properties. Titanium alloys with low interstitial elements, such as TA7, can maintain a certain plasticity at -253℃. Therefore, titanium alloy is also an important low-temperature structural material.
Titanium alloy is mainly used to make compressor parts for aircraft engines, followed by structural parts for rockets, missiles, and high-speed planes. In the mid-1960s, titanium and its alloys began to be used in general industry for the manufacture of electrolytic industry electrodes, condensers for power plants, heaters for petroleum refining and seawater desalination, and environmental pollution control devices. Titanium and its alloys have become corrosion-resistant structural materials. They are also used in the production of hydrogen storage materials and shape memory alloys. According to their uses, 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).
In conclusion, titanium alloy pipes play a significant role in various fields, regardless of their size. Therefore, we should not underestimate the importance of these materials.
