Titanium screw density and vibration reduction function summary

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 reactive metal, and its equilibrium potential is very low in thermodynamically corrosion-prone media. But in fact, 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 in 600℃ or higher temperature for a long time.

4. Good low temperature resistance: the strength of TA7(Ti-5Al-2.5Sn), TC4(Ti-6Al-4V) and Ti-2.5Zr-1.5Mo and other low temperature titanium alloys 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 metal. It is ideal for cryogenic vessels, storage tanks and other equipment.

5. Strong vibration reduction function: compared with steel and copper, titanium has longer attenuation time after mechanical and electrical vibration.

6. Non-magnetic, non-toxic: Titanium is a non-magnetic metal and will not be magnetized in a large magnetic field. It is non-toxic and has good compatibility with human tissues and blood, so it is chosen by the medical community.

7. Tensile strength close to its bending strength: the function of titanium shows that its bending strength ratio (tensile strength/bending strength) is high, indicating that the plastic deformation of titanium is poor. Because the ratio of the bending limit to the elastic modulus of titanium is large, the springback ability of titanium 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, but due to its excellent corrosion resistance, titanium can greatly reduce the wall thickness, and surface and steam drop condensation heat transfer methods may reduce the heat group, if the surface is not scale, the thermal resistance decreases, thus greatly improve the titanium heat transfer function.

9. Low elastic modulus: the elastic modulus of titanium at room temperature is 106.4 high standard a, which is 57% of steel.

10. Suction function: Titanium screw is a chemically very active metal, 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.
