High Strength Titanium Alloy Flange Bolt

BJCJTi offers high-performance Titanium Alloy Flange Bolts (Gr5/Gr2 available) featuring exceptional lightweight, corrosion resistance, and high strength for aerospace, automotive, and marine engineering.

Flanged Head Structure
The bolt features a wide flanged head, which increases the contact area with the connected component compared to standard bolts. This design helps to distribute the clamping force more evenly, reducing pressure per unit area and preventing deformation or damage to the surface of the connected part caused by excessive localized force.

For example, in the fuel pipeline systems of aircraft engines, the large flange of the bolt ensures a tight and stable connection, even under high-pressure fuel flow, vibrations, and complex stress conditions—effectively preventing fuel leakage.BJCJTi offers high-performance Titanium Alloy Flange Bolts (Gr5/Gr2 available) featuring exceptional lightweight, corrosion resistance, and high strength for aerospace, automotive, and marine engineering.

    Thread Section

    The threads are manufactured using high-precision machining, ensuring accurate thread profiles and consistent pitch. This guarantees a smooth fit with nuts or threaded holes, allowing for easy installation and removal, while providing reliable clamping force.

    Thread strength and precision directly impact overall bolt performance. In power transmission components of heavy machinery, high-precision threads ensure that connections remain secure under high torque and frequent vibrations, maintaining the safe operation of equipment.

    Material Characteristics icon_03

    Lightweight Advantage
    Titanium alloys have a density of about 60% that of steel while maintaining excellent strength. For instance, the commonly used GR5 titanium alloy has a density of approximately 4.51 g/cm³ and a tensile strength exceeding 900 MPa.
    In weight-sensitive fields like aerospace, titanium alloy flange bolts significantly reduce structural weight, lowering energy consumption and improving flight performance and fuel efficiency. In satellite structures, replacing traditional steel bolts with titanium alloy flange bolts can greatly reduce launch weight and cost without compromising structural integrity.
    advantage-2
    Outstanding Corrosion Resistance
    Titanium alloys naturally form a dense and stable oxide layer on their surface, which protects against a wide range of corrosive substances.
    In marine environments, where seawater is highly corrosive to metals, titanium alloy flange bolts are widely used in ships, offshore drilling platforms, and similar facilities.
    In chemical processing, where exposure to strong acids and alkalis is common, titanium alloy bolts maintain stable performance over time, ensuring the reliability of equipment connections and reducing maintenance and replacement costs.
    advantage-2
    Excellent High- and Low-Temperature Performance
    Titanium alloys maintain stable mechanical properties across a wide temperature range. At extremely low temperatures (e.g., –250 °C for liquid hydrogen tanks), titanium does not exhibit cold brittleness; instead, its strength increases while retaining good toughness, ensuring safe and reliable connections.
    In high-temperature conditions, such as those found in jet engine combustion chambers, some titanium alloys can withstand temperatures up to around 550 °C. They offer excellent thermal stability and low thermal expansion, preventing loosening or failure due to thermal expansion and contraction.
    advantage-2
    Biocompatibility and Low Magnetic Permeability
    Titanium alloys are highly biocompatible with human tissues and do not trigger rejection responses, making them widely used in medical devices such as orthopedic implants and dental fixtures.
    Additionally, with extremely low magnetic permeability, titanium alloy flange bolts are ideal for use in precision instruments and electronic equipment where magnetic interference must be avoided. This ensures accurate measurement and stable operation of sensitive devices.

    Surface Treatments

    Natural Titanium Finish

    Retains the original color and metallic texture of the titanium alloy. The naturally formed oxide film on the surface already provides a certain level of protection. This finish is ideal for applications that favor simplicity and cost-efficiency while maintaining a clean, industrial aesthetic.

    Physical Vapor Deposition (PVD)

    Offers a variety of rich colors such as gold, black, and rainbow. PVD enhances the visual appeal while significantly increasing surface hardness and wear resistance. It is commonly used in high-end decorative applications, electronics, and luxury hardware.

    Anodizing

    Produces oxide films in a wide range of colors including gold, black, rainbow, blue, green, pink, and purple. Anodizing not only improves aesthetic value but also enhances corrosion resistance and electrical insulation. It is widely used in aerospace, architectural decoration, and consumer products

    Micro-Arc Oxidation (MAO)

    Generates ceramic-like oxide coatings in colors such as gray and brown. This process forms a hard, wear-resistant, and corrosion-resistant ceramic layer on the titanium surface, making it suitable for applications in machinery, chemical processing, and other industries with high surface performance requirements.
