Titanium alloy tubing is a tube made of titanium alloy.
It has high mechanical properties, excellent stamping performance, and can be welded in various forms. The strength of the welded joint can reach 90% of the strength of the base metal, and the cutting performance is good. Titanium tubes have high corrosion resistance to chlorides, sulfides, and ammonia. The corrosion resistance of titanium in seawater is higher than that of aluminum alloys, stainless steel, and nickel based alloys. Titanium also has strong impact resistance.
Compared With Other Metal Materials, Titanium Alloy Tubing Has The Following Advantages
1. High strength (tensile strength/density), the tensile strength can reach 100-140kgf/mm2, while the density is only 60% of steel.
2. Good strength at medium temperature, with a usage temperature several hundred degrees higher than aluminum alloy. It can still maintain the required strength at medium temperature and can work for a long time at temperatures of 450-500 ℃.
3. Good corrosion resistance, immediately forming a uniform and dense oxide film on the surface of titanium in the atmosphere, with the ability to resist corrosion from various media. Titanium usually has good corrosion resistance in oxidizing and neutral media, and its corrosion resistance is even better in seawater, wet chlorine gas, and chloride solutions. However, in reducing media such as hydrochloric acid solutions, titanium has poor corrosion resistance.
4. Titanium alloys with good low-temperature performance and extremely low interstitial elements, such as TA7, can maintain a certain degree of plasticity at -253 ℃.
5. Low elastic modulus, low thermal conductivity, and no ferromagnetism.
6. High hardness.
7. Poor stamping performance, good thermoplasticity.
