Titanium screw

Titanium density of 4.51g/cm³, higher than aluminum, and lower than steel, and copper, nickel strength is much higher than other metals. Titanium alloy made of screws lightweight and strong, specializing in race tuning, hanging white iron. Titanium screws are high-strength, lightweight, corrosion-resistant screws, commonly used in aerospace, medical equipment, and other fields. Titanium has good corrosion resistance and will not cause rust due to long-term exposure to humid environments or strong acids and alkalis. Therefore, They are one of the best choices for equipment that needs to be installed in humid, high-temperature, corrosive, and other environments.

Product Information

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 medium 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, its 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 brittleness, low-temperature containers, storage tanks, and other equipment, the ideal material.

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, non-toxic and 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 molding of plastic deformation is poor. As the yield limit of titanium and the ratio of the modulus of elasticity is large, titanium molding rebound capacity.

8, good heat transfer performance: titanium metal thermal conductivity, although lower than carbon steel and copper, but because of titanium's excellent corrosion resistance, 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 temperature.

Titanium screws in various fields of application

1. nuclear industry
In the development process of the nuclear industry, titanium screws and other titanium components is an essential part of the construction process in the nuclear reactor, many of the components of the pipeline and related parts, in addition to the use of hafnium-zirconium metal, but also need a large number of titanium and titanium alloy metal, with the continuous development of the nuclear industry, the value of titanium will continue to increase.

2. automobile industry
Titanium is an essential metal in the automotive industry, because of its quality and strength of the performance of the enterprise manufacturers love, of course, in recent years the emergence of carbon fiber materials, but still can not shake the dominant position of titanium in the racing industry.

With the development of the entire automotive industry, titanium will not only be used in the manufacture of racing cars in the civilian automotive industry will also be used in large quantities, the Japanese automobile the use of titanium materials has exceeded 600 tons, of course, the global automotive industry is accelerating the use of titanium materials.

3. Aerospace industry
Widespread use of titanium materials in the aerospace industry, I believe we will not be unfamiliar, after all, China's aerospace industry has made great progress, then the introduction of the relevant will not be less, so in the media reports we also recognize that China's space rockets and the capsule will be used in titanium, civil aircraft with titanium accounted for the amount of frame weight of about 20 to 25%; in addition to the strategic rocket engines, spacecraft ( In addition, strategic rocket engines, spacecraft ( such as Shenzhou V, Shenzhou VI ), satellite antennae, etc. also use titanium in large quantities.

What are the advantages of titanium screws over traditional screws?

As the raw material element of the production of it, titanium is a very active metal, compared with traditional stainless steel, it has better flexibility and oxidation resistance.
More widely used in various industries, ordinary stainless steel screws in high-pressure environments with it compared to titanium screws, They are more resistant to pressure, so aerospace metal will choose titanium alloy to make, titanium screws as one of the connectors.
