Titanium Wheel Hub Bolt

what is titanium wheel hub bolt?

Titanium wheel hub bolt is a high-performance auto part, which is widely used in the field of automobile modification and high-performance vehicles due to its high strength, lightweight and corrosion resistance.and it`s the Bolts on which the vehicle attaches the wheels.

Wheel bolts are high-strength bolts that connect the wheels of a vehicle. The connection position is the hub unit bearing of the wheel! Generally, 10.9 is used for micro vehicles, and 12.9 is used for large and medium-sized vehicles! The structure of the hub bolt is generally knurled key gear and threaded gear! And a hat head! Most of the T-head hub bolts are grade 8.8 or above, which bears the large torque connection between the car wheel hub and the axle! Most of the double-ended wheel bolts are of grade 4.8 or above, which are responsible for the connection of light torque between the outer hub housing of the automobile and the tire.

Titanium wheel hub bolts have the following main features:

‌High strength: The tensile strength of titanium alloy can reach more than 950Mpa, which ensures the tightening and safety of wheel bolts under extreme driving conditions.

‌Lightweight: Titanium alloy is much less dense than steel, and the use of titanium wheel hub bolts can significantly reduce unsprung mass, resulting in improved vehicle responsiveness and fuel economy.

‌Corrosion resistance: Titanium alloy has extremely strong corrosion resistance, even under harsh environmental conditions, such as salt spray, moisture, etc., it can effectively prevent corrosion and prolong the service life.

‌Aesthetics: The unique metallic luster of titanium alloy and customizable colors (such as gold, black, burnt blue, etc.) add highlights to the appearance of the vehicle and become a decorative accessory to enhance the appearance of the car.

Titanium wheel bolts offer significant advantages over conventional materials such as steel or aluminum:

‌Compared with steel bolts: although steel bolts have high strength, they are heavy and are not conducive to vehicle lightweight; Titanium bolts, on the other hand, offer a perfect combination of high strength and light weight

‌Compared with aluminum bolts: although aluminum bolts are light, they have poor corrosion resistance and are prone to rust after long-term use; Titanium bolts, on the other hand, combine high strength with excellent corrosion resistance.

In automobile modification and high-performance vehicles, titanium wheel bolts are particularly widely used. For owners who pursue strict performance and individuality, replacing titanium wheel bolts can not only improve the visual effect of the vehicle, but also directly enhance the connection between the wheel hub and the tire, and improve driving stability and safety.

In addition, titanium wheel bolts have become one of the indispensable accessories due to their excellent performance advantages in high-performance vehicles such as racing cars and supercars.

‌The main reason why titanium wheel hub bolts appear in various colors is through anodizing and color oxidation processing technology‌. These technologies work by forming an oxide film on the surface of the titanium bolt, using the interference of light to present different colors.

Anodizing and color oxidation treatment technology

‌Anodizing‌: Using a titanium bolt as an anode and placing it in an electrolyte, the electrochemical reaction causes an oxidation reaction on the titanium surface to form an oxide film. This oxide film displays various colors due to the interference of light. Anodizing technology has the advantages of strong corrosion resistance and wear resistance, but the hardness is lower and the thickness may be uneven‌

‌Color oxidation‌: Through the electrochemical coloring method, the titanium alloy is soaked in the electrolytic coloring liquid, and the electrochemical reaction causes the formation of a colored oxide film on the surface. This method uses a variety of inorganic strong acid compounds. The solution is stable and does not contain toxic and harmful substances, but the cost is high and the color persistence is poor‌.

Temperature ranges corresponding to different colors

Titanium metal will show different colors at different temperatures:

‌200℃‌: silvery white

‌300℃‌: light yellow

‌400℃‌: golden yellow

‌500℃‌: blue

‌600℃‌: purple

‌700-800℃‌: gray red

‌900℃‌: Gray‌3

These color changes are caused by the interference of light with the oxide film formed when the titanium metal reacts with oxygen during the heating process.
