Titanium screw density and vibration reduction function!
The density and vibration reduction function of titanium screws are summarized as follows:
1. Low density, high specific strength: The density of titanium is 4.51g/cm3, higher than that of aluminum, but lower than that of steel, copper, and nickel.
2. Corrosion resistance: Titanium is a very active metal with a low equilibrium potential in a medium 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 the decrease of temperature, but the plasticity changes very little. It can maintain good ductility and toughness at -196-253 ℃ and avoid cold brittleness of the metal. 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, non-toxic: Titanium is a non-magnetic metal that will not be magnetized in a large magnetic field. It is non-toxic and has good compatibility with human tissues and blood, therefore it is chosen by the medical community.
7. The tensile strength is close to its bending strength: the function of titanium indicates that its Flexural strength is higher than (tensile strength/Flexural strength), indicating that the plastic deformation of titanium is poor. Due to the large ratio of the bending limit to the elastic modulus of titanium, its resilience is high.
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 condensation of surface and steam heat transfer methods will reduce thermal groups. If the surface does not scale, the thermal resistance will be reduced, greatly improving the heat transfer function of titanium.
9. Low elastic modulus: The elastic modulus of titanium is 106.4 high standard a at room temperature, which is 57% of that of steel.
10. Inspiratory 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.
