As a raw material element for titanium bolts, titanium is a highly reactive metal. Compared to traditional stainless steel, titanium bolts have better flexibility and oxidation resistance. “The application of ordinary stainless steel bolts in various industries is more extensive. Compared to titanium bolts under high-pressure environments, titanium bolts have stronger compression resistance. Therefore, in aerospace metals, titanium alloys are often selected for production, with titanium bolts as the connecting pieces
Titanium screw classification:
Titanium bolts: round head bolts, self tapping bolts, hexagon bolts, countersunk head bolts, slotted bolts, square head bolts, stud bolts, non-standard bolts, fastening bolts, standard bolts, flat head bolts
Differences between titanium bolts and traditional bolts:
Titanium bolts are the same as ordinary stainless steel, iron, and copper bolts, except that the material is titanium. The raw materials for titanium bolts are relatively expensive, and they are also beautifully made. It seems like handicrafts. Titanium is resistant to acid and alkali corrosion, so the price of titanium bolts is generally relatively high.
Low density, high specific strength: The density of titanium metal is 4.51 g/cm3, higher than aluminum but lower than steel, copper, and nickel, but its specific strength ranks first among metals.
Corrosion resistance: Titanium is a very active metal with a low equilibrium potential and a strong thermodynamic corrosion tendency in the medium. However, titanium is actually very stable in many media, such as oxidizing, neutral, and weakly reducing media, where it is resistant to corrosion.
Good heat resistance: The new titanium alloy can be used for a long time at temperatures of 600 ℃ or higher.
Good low temperature resistance: Low temperature titanium alloys such as titanium alloys TA7 (Ti-5Al-2.5Sn), TC4 (Ti-6Al-4V), and Ti-2.5Zr-1.5Mo, whose strength increases with decreasing temperature, have little plastic change. Maintains good ductility and toughness at low temperatures of – 196-253 ℃, avoiding cold brittleness of metals, making it an ideal material for cryogenic containers, storage tanks, and other equipment.
Strong damping resistance: Compared with steel and copper metals, titanium metal has a long vibration attenuation time after being subjected to mechanical and electrical vibration.
Non magnetic and non-toxic: Titanium is a non magnetic metal that will not be magnetized in large magnetic fields. It is non-toxic and has good compatibility with human tissues and blood, so it is used in the medical industry.
Tensile strength is close to its yield strength: This property of titanium indicates that its yield strength ratio (tensile strength/yield strength) is high, indicating poor plastic deformation of metallic titanium materials during forming. Due to the large ratio of the yield limit to the elastic modulus of titanium, the resilience of titanium during molding is large.
Good heat transfer performance: Although the thermal conductivity of metallic titanium is lower than that of carbon steel and copper, due to its excellent corrosion resistance, the wall thickness can be greatly reduced. Moreover, the heat transfer method between the surface and steam is droplet condensation, reducing heat groups. Without fouling on the surface, it can also reduce thermal resistance, significantly improving the heat transfer performance of titanium.
Low elastic modulus: The elastic modulus of titanium is 106.4 high standard a at room temperature, which is 57% of that of steel.
Aspiration performance: Titanium screws are a chemically active metal that can react with many elements and compounds at high temperatures. Titanium gettering mainly refers to the reaction with carbon, hydrogen, nitrogen, and oxygen at high temperatures.
Applications of titanium bolts in various fields:
- Automobile industry
Titanium is an essential metal in the racing industry, and is deeply loved by enterprise manufacturers due to its high quality and strength. Of course, materials such as carbon fiber have emerged in recent years, but it still cannot shake the dominant position of titanium in the racing industry. With the development of the entire automotive industry, titanium metal will not only be used for racing manufacturing, but also be widely used in the civil automotive industry. Japanese cars have already used more than 600 tons of titanium metal materials. Of course, the global automotive industry is accelerating the use of titanium metal materials.
- Nuclear industry
In the development of the nuclear industry, titanium metal components such as titanium screws are essential components. In the construction process of nuclear reactors, many of the components, pipelines, and related components, in addition to using hafnium and zirconium metal, also require a large amount of titanium metal and titanium alloy metal. With the continuous development of the nuclear industry, the value of titanium metal will continue to increase.
- Aerospace industry
The widespread use of titanium materials in the aerospace industry is no stranger to everyone. After all, China’s aerospace industry has made tremendous progress, so there will be no shortage of relevant introductions. Therefore, in media reports, we also recognize that titanium is used in China’s space rockets and spacecraft, and the amount of titanium used in civil aircraft accounts for about 20-25% of the weight of the framework; In addition, titanium is also widely used in strategic rocket engines, spacecraft (such as Shenzhou V and Shenzhou VI), and satellite antennas.
Shenzhen JINGBANG focuses on customized production of titanium bolts. The company mainly produces and processes titanium bolts, lengthened bolts, small bolts, and other non-standard bolts
