The density of titanium and its vibration-damping function are summarized below:
1. Low density, high specific strength: the density of titanium is 4.51g / cm3, higher than aluminum, but lower than steel, copper, and nickel.
2. Corrosion resistance: titanium is a very active metal with a low equilibrium potential in media with a thermodynamic tendency to corrode. However, titanium is actually very stable in many media, such as oxidizing, neutral and weakly reducing media.
3. Good heat resistance: new titanium alloys can be used for a long time at 600℃ or higher.
4. Good low-temperature resistance: the strength of low-temperature titanium alloys such as TA7 (ti-5al-2.5sn), TC4 (Ti-6Al-4V), and ti-2.5zr-1.5mo increases with the decrease of temperature, but the plasticity changes are very small. It maintains good ductility and toughness at -196-253°C and avoids metal cold embrittlement. It is an ideal material for cryogenic containers, storage tanks, and other equipment.
5. Strong vibration damping: Compared with steel and copper, titanium has a longer decay time after mechanical and electrical vibrations.
6. Non-magnetic, non-toxic: Titanium is a non-magnetic metal and will not be magnetized in large magnetic fields. It is non-toxic and has good compatibility with human tissues and blood, so it is chosen by the medical profession.
7. The tensile strength is close to its bending strength: the function of titanium shows that its bending strength is higher than (tensile strength/bending strength), indicating that titanium has poor plastic deformation. Because the ratio of titanium’s bending limit to its modulus of elasticity is large, titanium’s resilience is large.
8. Good heat transfer function: Although the coefficient of thermal conductivity of titanium is lower than the coefficient of thermal conductivity of carbon steel and copper, because of its excellent corrosion resistance, titanium wall thickness can be greatly reduced, and the surface and the steam heat transfer method down condensation will reduce the heat group if the surface is not scaling, then the thermal resistance will be lowered, which greatly improves the function of heat transfer of titanium.
9. Low modulus of elasticity: the modulus of elasticity of titanium at room temperature is 106.4 high standard a, which is 57% of steel.
10. Gas absorption function: titanium is a chemically very active metal, which can react with many elements and compounds at high temperatures. Titanium gas absorption mainly refers to the reaction with carbon, hydrogen, nitrogen, and oxygen at high temperatures.
