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.
-
スレッドタイプ: 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
-
目的: 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
-
航空宇宙: Lightweight, high-strength fasteners for aircraft and spacecraft.
-
Military/Defense: Low-visibility hardware for tactical equipment.
-
マリン: 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.
-
耐食性: 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.
