Compared with other alloy tubes, titanium and titanium alloys in the industry is much worse, which is mainly due to two factors, 1, titanium processing and production difficulties, resulting in titanium and titanium alloys in the market popularization of other metals slower, and to a certain extent affects the consumer's consumption habits. 2, people are accustomed to using the alloy materials that they are more often accustomed to use. But with the maturity and perfection of titanium and titanium alloy metallurgy as well as processing technology, many excellent properties of titanium have gradually been discovered and utilized, which has enhanced the popularity of titanium alloys to a certain extent, so what are the unique properties and advantages of titanium alloys, especially the special tube? You can mainly refer to the following points:
1, high specific strength. Specific strength refers to the ratio of tensile strength and density, titanium tube tensile strength can reach 100-140kgf/mm2, while the density is only 60% of other steel.
2, good low temperature performance. Generally speaking, like the titanium alloy with very low interstitial elements, such as TA7, it can maintain a certain degree of plasticity at -253 ℃, and other steel can not achieve this effect;
3, good corrosion resistance. This point has been introduced many times before, the corrosion resistance of titanium is very good, this is because in the atmosphere, such as titanium plate, titanium tube, titanium bar and other titanium products, the surface of the formation of a layer of uniform oxidized film, this layer of oxidized film has a very good corrosion resistance. After a variety of tests, titanium has good corrosion resistance in a variety of acids and alkalis, in terms of corrosion resistance, titanium is better than general stainless steel.
4, high strength. Titanium in up to 450-500 ℃ temperature can still work normally for a long time, which is other alloys can not do, and the use of titanium temperature than aluminum alloy hundreds of times higher.
In summary, it can be seen that the superior performance of titanium tubing makes it very unique in many specific environments and occasions.
