Why have titanium screws become a common accessory for bicycles? Is it because titanium screws have a high face value? Or does it have some magical function? Today we will reveal this question!
Bicycles use titanium screws because they are lighter, more durable, and tougher than ordinary screws. Lightweight is important in cycling because the weight of each part has an impact on speed and handling. The lightweight nature of them can effectively reduce the overall weight of the bike, making riding easier and more comfortable.
In addition, the corrosion resistance and toughness of titanium screws are excellent, which can effectively extend the service life of bicycle parts. Moreover, in extreme environments, such as bad weather and strong vibration, titanium screws can maintain stability and prevent bike parts from loosening or being damaged.
Of course, They are also more difficult and costly to make than ordinary screws, but for cyclists who pursue high quality and performance, this cost is worthwhile.
What are the advantages of titanium screws？
1, low density, high specific strength: the density of titanium metal is 4.51g/cm3, higher than aluminum and lower than steel, copper, and nickel, but the specific strength is located in the first metal.
2, corrosion resistance: titanium is a very active metal, and its equilibrium potential is very low, in the medium of thermodynamic corrosion tendency. But in fact, titanium is very stable in many media, such as titanium in oxidizing, neutral and weakly reducing media is corrosion resistant.
3, good heat resistance: new titanium alloy can be used for a long time at 600 ℃ or higher.
4, good low-temperature resistance: titanium alloy TA7 (Ti-5Al-2.5Sn), TC4 (Ti-6Al-4V), and Ti-2.5Zr-1.5Mo, etc. as a representative of low-temperature titanium alloys, titanium screw strength increases with the reduction of temperature, but the plasticity does not change much. In -196-253 ℃ low temperature to maintain good ductility and toughness, to avoid the metal cold embrittlement, is the ideal material for low-temperature containers, storage tanks, and other equipment.
5, strong anti-damping properties: titanium metal by mechanical vibration, and electrical vibration, compared with steel, and copper metal, its own vibration attenuation time is long.
6, non-magnetic, non-toxic: titanium is a non-magnetic metal, in a very large magnetic field that will not be magnetized, is non-toxic, and has good compatibility with human tissue and blood, so it is used by the medical profession.
7, tensile strength and its yield strength close to titanium of this performance shows its flexural strength ratio (tensile strength/yield strength) is high, said the titanium metal material in the forming of plastic deformation is poor. As the yield limit of titanium and the ratio of the modulus of elasticity of titanium is large, so that the rebound capacity of titanium molding.
8, good heat transfer performance: titanium metal thermal conductivity, although lower than carbon steel and copper, because of titanium's excellent corrosion resistance, so the wall thickness can be greatly reduced, and the surface of the heat transfer with the steam in the form of drops of condensation, reducing the heat group, too, the surface of the surface is not scaling can also reduce the thermal resistance, so that titanium's heat transfer performance is significantly improved.
9, low modulus of elasticity: titanium modulus of elasticity at room temperature is 106.4 high standard a, 57% of steel.
10, suction performance: titanium screw is very active chemical properties of the metal, and at high temperatures can react with many elements and compounds. Titanium suction mainly refers to the reaction with carbon, hydrogen, nitrogen, and oxygen at high temperatures.
Therefore, titanium screws have become a common accessory for bicycles not because of their high face value, but because of their lighter weight, corrosion resistance, and tougher performance.
