Titanium flange nut black

Cold heading process is one of the new processes for pressure machining of less or no cutting
metal. It is a processing method that utilizes the plastic deformation of metal under the action of
external forces, and with the aid of molds, redistributes and transfers the volume of metal to form
the required parts or blanks. The cold heading process is most suitable for producing standard
fasteners such as bolts, screws, nuts, rivets, and pins.etc

A titanium alloy flange nut with a black coating combines high-performance material properties with an enhanced aesthetic and functional surface finish. Below is an overall description of its key aspects:

1. Material: Titanium Alloy

• Grade: Typically made from Ti-6Al-4V (Grade 5) or similar high-strength titanium alloys.

• Properties:

  • High strength-to-weight ratio.

  • Excellent corrosion resistance (especially against saltwater and chemicals).

  • Good thermal stability and fatigue resistance.

  • Biocompatible (suitable for medical/aerospace applications).

2. Flange Nut Design

• Integrated Flange: The nut has a built-in washer-like flange that distributes clamping load, reducing the need for a separate washer.

• Thread Type: Typically metric (M-series) or imperial (UNC/UNF), depending on application.

• Hexagonal Drive: Standard wrenching surfaces (e.g., 6-point or 12-point).

3. Black Coating

• Purpose: Improves corrosion resistance, reduces light reflection (for stealth/low-visibility applications), and enhances wear resistance.

• Common Coating Types:

  • Anodizing (Black Oxide): Electrochemical process creating a durable, non-conductive oxide layer.

  • TiN (Titanium Nitride) or DLC (Diamond-Like Carbon): Hard, wear-resistant PVD coatings.

  • Black Oxide Conversion Coating: Provides mild corrosion resistance and aesthetic appeal.

  • Epoxy/Polymer Coatings: Used for added chemical resistance.

4. Applications

• Aerospace: Lightweight, high-strength fasteners for aircraft and spacecraft.

• Military/Defense: Low-visibility hardware for tactical equipment.

• Marine: Corrosion-resistant nuts for ships and offshore structures.

• Automotive/Racing: High-performance and weight-saving components.

• Medical: Biocompatible nuts for surgical implants/devices.

5. Advantages

• Lightweight: ~40% lighter than steel equivalents.

• Corrosion Resistance: Ideal for harsh environments.

Conclusion

A black-coated titanium alloy flange nut is a premium fastener designed for high-performance applications where weight savings, corrosion resistance, and durability are critical. The black coating adds both functional and visual benefits, making it suitable for aerospace, military, and industrial uses.
