Porca de flange em titânio preto

O processo de encabeçamento a frio é um dos novos processos para a maquinagem sob pressão com menos ou nenhum corte
metal. É um método de processamento que utiliza a deformação plástica do metal sob a ação de
forças externas e, com a ajuda de moldes, redistribui e transfere o volume de metal para formar
as peças ou os espaços em branco necessários. O processo de encabeçamento a frio é o mais adequado para a produção de
elementos de fixação, tais como cavilhas, parafusos, porcas, rebites, cavilhas, 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: Normalmente fabricado a partir de 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

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

• Tipo de rosca: 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

• Objetivo: 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. Aplicações

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

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

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

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

• Médico: Biocompatible nuts for surgical implants/devices.

5. Advantages

• Leve: ~40% lighter than steel equivalents.

• Resistência à corrosão: Ideal for harsh environments.

Conclusão

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.
