Summary of Titanium Screw Density and Vibration Reduction Function!
We have summarized the density and vibration reduction function of titanium screws into ten points:
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 highly reactive metal with a low equilibrium potential in media prone to thermodynamic corrosion. But in reality, titanium is very stable in many media, such as oxidizing, neutral, and weakly reducing media.
3. Good heat resistance: The new titanium alloy can be used for a long time at temperatures of 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 decreasing temperature, but the plasticity changes very little. Good ductility and toughness can be maintained at -196-253 ℃, while avoiding metal cold brittleness. It is an ideal material for low-temperature containers, storage tanks, and other equipment.
5. Powerful vibration reduction function: Compared with steel and copper, titanium has a longer attenuation time after mechanical and electrical vibrations.
6. Non magnetic and non-toxic: Titanium is a non-magnetic metal that will not be magnetized in large magnetic fields. It is non-toxic and has good compatibility with human tissues and blood, so it is selected by the medical community.
7. Tensile strength is close to its bending strength: The function of titanium indicates that its bending strength is higher than (tensile strength/bending strength), indicating poor plastic deformation of titanium. Because the ratio of the bending limit to the elastic modulus of titanium is high, titanium has a strong rebound ability.
8. Good heat transfer function: Although the thermal conductivity of titanium is lower than that of carbon steel and copper, due to its excellent corrosion resistance, the wall thickness of titanium can be greatly reduced, and the heat transfer method between the surface and steam decreases. Condensation will reduce thermal groups, and if the surface does not scale, the thermal resistance will decrease, greatly improving the heat transfer function of titanium.
9. Low elastic modulus: The elastic modulus of titanium at room temperature is 106.4 high standard a, which is 57% of that of steel.
10. Inhalation function: Titanium screws are a chemically active metal that 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.
2、 Vibration reduction function of titanium screws
Core features: Excellent damping characteristics and fatigue performance
The vibration reduction function of titanium alloy is another key advantage, mainly reflected in the following aspects:
High damping characteristics:
Principle: The lattice structure of titanium alloy can convert more vibration energy into thermal energy and dissipate it, rather than transferring or reflecting energy back like many steels. This inherent material property gives it a high damping capacity.
Effect: When the system (such as engine, bicycle frame, precision instrument) vibrates, using titanium screws can help attenuate the vibration faster, reduce resonance amplitude and duration.
Excellent fatigue performance:
Vibration is one of the main causes of metal fatigue. Titanium alloys have very high fatigue strength and fatigue crack propagation resistance under alternating loads (vibrations).
This means that in long-term, high-frequency vibration environments, titanium screws are less prone to fatigue failure than many steel screws, have a longer service life, and higher reliability.
The impact of low elastic modulus:
The elastic modulus of titanium (about 110 GPa) is lower than that of steel (about 200 GPa), which means it is "softer" and undergoes greater elastic deformation under the same load.
This greater elastic deformation can absorb and buffer a portion of the impact energy, thereby playing a role in vibration reduction to a certain extent. But this also means that at connections that require extremely high stiffness, redesign may be necessary.
Summary of vibration reduction function: Titanium screws can not only "absorb vibration" (high damping), but also "resist damage caused by vibration" (high fatigue strength).
