Products Description
Car Horn Tungsten Contact Rivets are precision components designed for demanding electrical contact applications. Utilizing innovative material combinations and advanced manufacturing processes, they ensure superior performance and long-term reliability in harsh operating environments. This product employs a unique tungsten sheet-metal substrate composite structure, perfectly combining the high melting point and arc erosion resistance of tungsten with the excellent conductivity and mechanical strength of an iron/copper substrate, providing an ideal solution for automotive horns, relays, and other electrical contact systems.
Key Advantages
Extra-long Electrical Life
The tungsten contact tip exhibits virtually no welding or severe ablation under repeated arc impacts, significantly outperforming traditional silver- or copper-based contacts. This makes it particularly suitable for high-frequency start/stop applications such as horns and relays for Tungsten Contacts.
Low Contact Resistance Stability
The copper feet (high-end models) provide excellent conductivity, while a nickel plating layer inhibits oxidation, ensuring minimal contact resistance fluctuations over long-term use and guaranteeing consistent signal/power transmission for Tungsten Rivet.
Resistant to Mechanical Fatigue
The optimized riveting structure can withstand the stamping and riveting stresses during automated assembly, resisting cracking or deformation and making it suitable for high-speed production lines for Tungsten Contact Rivets.
Strong Environmental Adaptability
The dual protection of a nickel plating layer and the tungsten body allows for stable operation in harsh environments such as high temperature and humidity, sulfur content, and salt spray, meeting automotive and industrial environmental requirements.
Detailed Showcase
Head Tungsten Sheet Details
The head tungsten sheet surface undergoes precision polishing, resulting in a smooth, flat surface free of burrs and defects, ensuring a good fit with the contact parts and reducing contact resistance. The tungsten sheet is precisely sized with regular edges, ensuring a perfect bond with the rivet and enhancing structural stability for Motorcycle Horn Tungsten Rivet.
Brazing Connection Details
The base nickel plating layer provides excellent oxidation protection; an intermediate diffusion barrier layer and functional surface coatings can be added according to customer requirements for Tungsten Contact Rivets for Tungsten Contact Rivets.
Foot Rivet Details
The iron/copper rivets in the feet have smooth surfaces, free of oxidation, scratches, and other defects. The rivet dimensions are precise, and the threads (if any) are regular, ensuring a precise fit with the assembled parts. The rivet tail is optimized for easy assembly, improving assembly efficiency for Tungsten Rivet.
Material Advantages
Tungsten's Irreplaceability
Tungsten's density (19.3 g/cm³) is 2.3 times that of iron, allowing it to withstand instantaneous impact forces of up to 500 N at contact closure, preventing poor contact due to deformation for Tungsten Contacts.
Copper/Iron Complementarity
Copper provides exceptional conductivity (8 times that of iron), while iron leverages its cost advantage to cover the low-to-mid-range market, meeting diverse needs for Tungsten Rivet.
Nickel Plating's Protective Logic
Nickel's chemical stability is superior to zinc and chromium, maintaining stable performance within a temperature range of -40℃ to 150℃, making it particularly suitable for extreme environments such as automotive engine compartments for Tungsten Contact Rivets.
