Titanium Bolt
Titanium Bolts are fasteners made from an extremely strong and corrosion-resistant metal called titanium. They're used in many aerospace, automotive, and industrial applications because of their strength and durability. These bolts can withstand higher temperatures than other metals while remaining lightweight. They're also non-magnetic, meaning they won't interfere with the operation of electronic devices nearby or be affected by magnetic fields like steel bolts sometimes can. Lastly, their low thermal expansion rate makes them ideal for engineering applications such as bridges, where consistency is critical.
Low density and high specific strength
The density of metallic titanium is 4.51g/cm3, which is higher than aluminum but lower than steel, copper, and nickel, but its specific strength is at the top of the metal.
Corrosion resistance
Titanium is a very active metal, its equilibrium potential is very low, and the thermodynamic corrosion tendency in the medium is high. But in fact, titanium is very stable in many media. For example, titanium is corrosion-resistant in oxidizing, neutral and weakly reducing media.
Good heat resistance
The new titanium alloy can be used for a long time at a temperature of 600°c or higher.
Good low-temperature resistance
Titanium alloy ta7 (ti-5al-2.5sn), tc4 (ti-6al-4v) and ti-2.5zr-1.5mo are represented by low-temperature titanium alloys whose strength decreases with the decrease of temperature. Improved, but the plastic change is not big. It maintains good ductility and toughness at low temperatures of -196-253°c, avoids cold brittleness of metals, and is an ideal material for cryogenic containers, storage boxes and other equipment.
Strong anti-damping performance
After metal titanium is subjected to mechanical vibration and electric vibration, its own vibration decay time is longer than steel and copper metal.
Non-magnetic and 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 adopted by the medical community.
Tensile strength is close to its yield strength
This property of titanium shows that its yield strength ratio (tensile strength/yield strength) is high, which means that the metal titanium material is poor in plastic deformation during forming. Due to the large ratio of the yield limit of titanium to the modulus of elasticity, 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 the excellent corrosion resistance of titanium, the wall thickness can be greatly reduced, and the heat exchange between the surface and the steam is dropwise condensation. The heat group is reduced, and the heat resistance can also be reduced without scaling on the surface, so that the heat transfer performance of titanium is significantly improved.
Low modulus of elasticity
The modulus of elasticity of titanium is 106.4 high standard a at room temperature, which is 57% of steel.
Absorption performance
Titanium screw is a kind of metal with very active chemical properties, which can react with many elements and compounds at high temperature. Titanium getter mainly refers to the reaction with carbon, hydrogen, nitrogen, and oxygen at high temperatures.

Several Surface Treatment Methods of Titanium Bolt
Mechanical polishing
Mechanical polishing is to rely on cutting or plastic deformation of the material surface and remove the convex part of the workpiece surface to get a smooth surface polishing method, the general use of oilstone strip, wool wheel, sandpaper, etc., mainly by hand, the surface quality requirements of the method can be used to superfine polishing. Super precision grinding and polishing is the use of special grinding tools, in the grinding and polishing fluid containing abrasive, the workpiece is pressed on the surface of the processing, for high-speed rotation movement. The surface roughness can be up to Ra0.008 microns with this technology, which is the best among various polishing methods. This method is often used in optical lens molds. Mechanical polishing is the main method of die polishing.
Chemical polishing
Chemical polishing is a process in which the concave part of the micro convex part of the surface is dissolved in a chemical medium to obtain a smooth surface. This method can polish the workpiece with complex shape and many workpieces at the same time with high efficiency. The surface roughness obtained from chemical polishing is generally Ra10 μm.
Electrolytic polishing
The basic principle of electropolishing is the same as that of chemical polishing, that is, by selectively dissolving the tiny protrusions on the surface of the material to make the surface smooth. Compared with chemical polishing, it can eliminate the effect of cathode reaction and has better effect.
Ultrasonic polishing
Ultrasonic polishing is a kind of machining method that utilizes tool section to make ultrasonic vibration and polish brittle and hard materials by abrasive suspension. The workpiece is put into the suspension of the abrasive and placed in the ultrasonic field together. By the oscillation of ultrasonic wave, the abrasive is grinded and polished on the workpiece surface. Ultrasonic machining macroscopic force is small, will not cause workpiece deformation, but tooling production and installation is more difficult.
Fluid polishing
Fluid polishing relies on the fluid and the abrasive particles carried by it to wash the workpiece surface to achieve the purpose of polishing. Hydrodynamic grinding is driven by hydraulic pressure, the medium is mainly used in the lower pressure under the flow of a good special compound (polymer material) and mixed with abrasive made, abrasive can be used silicon carbide powder.
Magnetic grinding and polishing
Magnetic grinding and polishing is the use of magnetic abrasive in the magnetic field under the action of the formation of abrasive brush, grinding workpiece processing. This method has high processing efficiency, good quality and easy to control processing conditions. With a suitable abrasive, the surface roughness of the machine can reach Ra 0.1 μm.
Edm ultrasonic composite polishing
In order to improve the polishing speed of the workpiece with the surface roughness Ra of 1.6 μm or more, the ultrasonic wave is combined with the special high-frequency narrow pulse high peak current pulse power supply for composite polishing, and the ultrasonic vibration and the electric pulse corrosion simultaneously act on the surface of the workpiece, and rapidly reduce The surface roughness, which is effective for polishing the rough surface of the mold after machining by car, milling, electric spark and wire cutting, is very effective.
What are the processing techniques for titanium screws
Coil processing
Refers to the original wire rod that the maker of the raw materials bought.A coil unit mainly includes the following parameters: A, brand b, product name c, specification d, material e, furnace number or batch number f, quantity or weight.
Thread drawing process
Operation process:
A) Small wire drawing: Since the minimum specification of the general disk unit is 5.5mm, and most small screws require smaller wire diameters, and the small screws deform greatly when formed. In order to reduce the processing stress caused by cold drawing and ensure the processability of the wire, the cold drawing of the wire is divided into two stages. First, a continuous wire drawing machine is used to roughly draw the disc element to a certain wire diameter, and then it is annealed. Eliminate the processing stress caused by rough drawing.
B) Large wire drawing: After the disc element is pickled, it is cold drawn to the required wire diameter through a wire drawing machine. Suitable for wires used
Cold heading process
To shape it through the interaction between molds, first cut the wire rod and make it into a screw blank to form the head, cross recess (or other head shape), thread blank diameter and rod length, rounded corners under the head, etc.
Description: It can be designed according to the needs of customers. Commonly used head types are p head, b head, f head, t head, etc. Commonly used groove types include cross groove, straight groove, plum blossom groove, inner hexagonal groove, etc.
Teeth rubbing process
The cold-forged blank is rolled into threads, and the threads are formed through the interaction between the movable die plate and the fixed die plate.
Heat treatment process
A) Purpose: To obtain higher hardness and strength of screws after cold heading.
B) Function: Achieve self-tapping locking of metal and improve the mechanical properties of metal parts, such as torsion resistance, tensile resistance, and wear resistance.
C) Annealing: (700℃x 4hr): Elongated structure – Regular polygonization.
Electroplating process (optional)
The surface of the electroplated product can present the required color effect and surface anti-oxidation coating effect.
Understand the grades of titanium
The first step in choosing the best titanium bolt is understanding the various available grades of titanium. A bolt's grade is a measure of its strength. Naturally, the higher the grade, the stronger the bolt. Titanium bolts typically come in grades 1 through 5, with grade 5 being the strongest. If you're working on a project where strength is a top priority, you'll want to opt for grade 5 titanium bolts.
Metric or imperial?
Titanium bolts are available in both metric and imperial sizes. Metric sizes are typically used in europe and asia, while imperial sizes are more common in the united states. When choosing titanium bolts, be sure to select the correct size for your project.
Thread pitch
The thread pitch is the distance between threads on a screw or bolt. Titanium bolts are available in a variety of thread pitches, from fine to coarse. Coarse thread pitches are stronger and less likely to strip, while fine thread pitches are more precise but weaker. Choose the thread pitch that is best suited for your project.
Head style
Titanium bolts are available with various head styles, including hex heads, flanged heads, button heads, and countersunk heads. Hex heads are the most common type of bolt head and can be used with a wrench or socket driver. Flanged heads have a raised area around the bolt head that helps to distribute the load evenly and prevent stripping.
Consider the bolt's application
Another important factor to consider is the application of the bolt. Are you using the bolt in a marine or saltwater environment? If so, you'll want to choose a titanium bolt with high corrosion resistance, such as grade 2 or grade 3. On the other hand, if you're using the bolt in a high-temperature environment, you may opt for grade 4 titanium, which is known for its thermal resistance.
Choose the right size and thread
Choosing the right size and thread for your titanium bolt is also important. The size of the bolt refers to its diameter, while its thread refers to the amount of spiraled ridges that wrap around the bolt's shaft. You'll want to choose a size and thread compatible with your project's other components. Remember that titanium bolts are slightly smaller in diameter than their steel counterparts, so you may need to adjust your measurements accordingly.
Consider the bolt's coating
Finally, consider the coating of the bolt. While titanium is naturally resistant to corrosion and wear, many bolts are coated with additional layers of protection. Some coatings, such as anodization, can further improve the bolt's corrosion resistance, while others, such as cadmium plating, can enhance its wear resistance. In addition, coatings can come in various colours, which can be useful for identifying different bolts in your project.
