Not So Important Stuff (For your reading)
Titanium is almost the only thing in the world completely non-toxic to human body, it is the top aerospace materials that able to adapt to the harsh conditions of outer space, but also can be safely implanted in the body become a part of the body of medical equipment timber.
1. Healthy, Environment & Human-friendly
As titanium is non-toxic & non-reactive with human body/blood, it is widely adopted in the medical for making human apparatus. Titanium also cannot be magnetised
Titanium is 4.51g/cm3 in density, higher than aluminium, lower than steel, copper and nickel, whose intensity tops in all metals. In other words, its weight nearly aluminum at the same volume. However, its intensity is stronger than aluminium and even steel.
3. Free from rust, acids & bases
Titanium is kept rust-proof in deep sea and stable in all kinds of media, like hydrochloric acid, nitric acid and even mixed acid. The reason is titanium generates a high density and hard oxide layer, which protects it from corrosion
4. Heat & Low temperature resistance
The melting point of Titanium is extremely high, and Titanium can be used for a long time in over 600 Degree Celsius environment, its intensity gets intensified as the temperatures falls down. But its plasticity can be kept almost constant. The metal remains in good ductility even at -253 Degree Celsius without being brittle. For this reason, titanium is the ideal material for low-temperature containers
5. Stronger than steel
Titanium shows a high ultimate performance (tensile strength/yield strength),that means titanium products not easy to deform after forming. Go this big ratio, Ti makes a big resilience when the titanium products form.
6. Good heat transfer performance
Titanium metal's thermal conductivity is lower than the carbon steel and copper, but because of its excellent corrosion resistance, so the wall thickness can be greatly attenuated, and the surface and steam's heat exchange is drop wise condensation, the heat resistance is reduced, it can be also reduced if the titanium surface is fouling-free, so that the titanium heat exchange performance is improved obviously.
