What are the advantages of titanium screws?

As the raw material element of titanium screws, titanium is a kind of metal with strong activity. Compared with traditional stainless steel, titanium screws have better flexibility and oxidation resistance.

In various industries more widely used, ordinary stainless steel screws in high pressure environment compared with titanium screws, titanium screws have stronger compression capacity, so in aerospace metal, will choose titanium alloy to make, titanium screws as one of the connectors.

Titanium screw and material advantage

1, small density, high specific strength: titanium density of 4.51g/cm3, higher than aluminum and lower than steel, copper, nickel, but the specific strength is located in the first metal.

2, corrosion resistance: titanium is a very active metal, its balance potential is very low, the thermodynamic corrosion tendency in the medium is large. But in fact titanium is very stable in many media, such as titanium in oxidizing, neutral and weak reducing media is corrosion resistant.

3, good heat resistance: the new titanium alloy can be used at 600℃ or higher temperature for a long time.

4, good low temperature resistance: titanium alloy TA7 (Ti-5Al-2.5Sn), TC4(Ti-6Al-4V) and Ti-2.5Zr-1.5Mo represented by the low temperature titanium alloy, its strength increases with the decrease of temperature, but the plastic change is little. It maintains good ductility and toughness at -196-253℃ and avoids cold brittleness of metal. It is an ideal material for cryogenic containers, storage tanks and other equipment.

5, strong damping performance: titanium metal by mechanical vibration, electrical vibration, compared with steel, copper, its own vibration attenuation time is long.

6, non-magnetic, non-toxic: titanium is a non-magnetic metal, in a large magnetic field will not be magnetized, non-toxic and has a good compatibility with human tissue and blood, so it is used by the medical community.

7, the tensile strength and its yield strength is close to: this performance of titanium shows that the strength ratio (tensile strength/yield strength) is high, indicating that the metal titanium material in the forming of plastic deformation. Due to the large ratio between the yield limit and elastic modulus of titanium, the springback ability of titanium forming is large.

8, good heat transfer performance: although the thermal conductivity of titanium metal is lower than carbon steel and copper, but because of the excellent corrosion resistance of titanium, so the wall thickness can be greatly reduced, and the surface and steam heat transfer mode for droplet condensation, reduce the heat group, too surface no scaling can also reduce the thermal resistance, the heat transfer performance of titanium significantly improved.

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, suction performance: titanium screw is a kind of chemical properties are very active metal, at high temperature can react with many elements and compounds. Titanium suction mainly refers to the reaction with carbon, hydrogen, nitrogen and oxygen at high temperature."
