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 Safety Wire Nut Aluminum Oxide Yellow is a specialized type of wire connector designed for secure and reliable electrical connections, particularly in high-temperature or harsh environments. Here’s an overall description of its key features:
1. Material & Composition
-
Body Material: Typically made from high-grade thermoset plastic ou flame-retardant nylon for durability.
-
Internal Coating/Insert: Contains aluminum oxide (Al₂O₃), a ceramic compound known for its high thermal resistance and electrical insulation properties.
-
Cor: Yellow (often indicating a specific size or temperature rating).
2. Key Features
-
High-Temperature Resistance: The aluminum oxide component allows the wire nut to withstand extreme heat, making it suitable for industrial, automotive, or aerospace applications.
-
Secure Connection: Features a spring-loaded metal coil (usually made of copper or steel) that ensures a tight, vibration-resistant connection.
-
Flame Retardant: The shell material resists burning and melting, enhancing safety in electrical systems.
-
Corrosion Resistance: Aluminum oxide provides protection against oxidation and chemical degradation.

3. Applications
-
Used in high-temperature environments (e.g., furnaces, engines, industrial machinery).
-
Suitable for automotive wiring, aerospace, and marine applications where vibration resistance is critical.
-
Ideal for aluminum-to-copper wire connections (if rated for such use).
4. Safety Standards & Certifications
-
May comply with UL (Underwriters Laboratories), CSA, or IEC standards for electrical safety.
-
Rated for specific voltage (e.g., 600V) and temperature ranges (e.g., -40°C to +150°C or higher).
