TitanNieten

TitanNieten are rivets manufactured from titanium or titanium alloys, used to join components in structures where high strength and low weight are required. They offer a favorable strength-to-weight ratio and excellent corrosion resistance, making them common in aerospace, automotive, marine, and chemical-processing applications.

Materials and designs: The most common TitanNieten are solid rivets forged from Ti-6Al-4V or commercially pure titanium. Heads are typically dome-shaped, with flush or countersunk variants available. Some versions are heat-treated or anodized to improve surface properties. Mechanical properties depend on alloy and treatment, delivering high tensile and shear strengths and low density compared with steel.

Manufacture and installation: Titanium rivets are produced by forging and extrusion, then finished to precise tolerances. Installation uses standard or high-strength riveting tools, but care is required to avoid galling and work hardening. Lubricants compatible with titanium are often used to control friction during driving. When fastened to dissimilar metals, galvanic corrosion can occur, so isolating spacers or protective coatings may be employed.

Performance and limitations: TitanNieten provide corrosion resistance, high temperature tolerance, and weight savings. They are more expensive than aluminum rivets and may require specialized equipment and processing; availability is more limited, and removal can be challenging due to work hardening.

Applications: Widely used in aircraft airframe and engine assemblies, spacecraft, high-performance automotive components, and chemical-processing equipment where corrosive environments or high temperatures exist.
