Products Description
Our tungsten rivets are designed as critical conductive components in electrical systems, featuring a two-layer structure:
Head: High-purity tungsten (≥99.95%), chosen for its ultra-high melting point (3410°C) and exceptional arc resistance, making it ideal for suppressing electrical erosion in high-frequency switching.
Base: Select between iron (cost-effective) for standard applications or copper (high-end) for enhanced conductivity and thermal management, both brazed to the tungsten head using precision furnace brazing for seamless integration.
Surface Treatment: A protective nickel plating (5-8μm) ensures long-term oxidation resistance, even in humid or corrosive environments.
These copper tungsten contacts (for premium models) and solid tungsten contact rivets (for standard models) are rigorously tested to meet international standards, providing a durable solution for both automotive and industrial electrical appliances.
Superior Material Performance
Tungsten Head Excellence
Withstands continuous operating temperatures up to 200°C and momentary arcs exceeding 1000°C, reducing contact wear by 50% compared to silver-based alternatives.
Maintains low contact resistance (≤10mΩ for iron base, ≤8mΩ for copper base) even after 100,000+ switching cycles, ensuring stable signal transmission in motorcycle horns.
Dual Base Options
Iron Base: Economical choice for mass-market motorcycles and basic automotive horns, balancing cost and reliability.
Copper Base: Optimized for high-end vehicles and smart home relays, offering 20% better electrical conductivity (≥99% IACS) and superior heat dissipation.
Precision Brazing Technology
Furnace Brazing Expertise
Our proprietary brazing process at 1000+°C creates a metallurgical bond with shear strength >80MPa, passing 100,000+ vibration cycles (per GB/T 2423.10) without detachment-critical for motorcycle horns exposed to constant engine vibration.
Nickel Plating Protection
The 5-8μm nickel layer passes 48+ hours of salt fog testing, preventing oxidation and ensuring long-term performance in rainy or coastal environments.
Why Choose Our Tungsten Rivets?
Technical Leadership: Over the past decade, we have been deeply dedicated to the manufacturing of tungsten contacts, establishing ourselves as a leader in this specialized field. With in-house furnace brazing capabilities, we meticulously control the high-temperature joining process of tungsten and other metals. Our precision machining facilities ensure that each contact is crafted to exact specifications, with tight tolerances and superior surface finishes.
Problem Solver: Our Motorcycle Horn Tungsten Rivets are engineered to address and eliminate common issues faced in electrical contact applications. Contact welding, a frequent problem in high-current environments, is prevented through the use of high-purity tungsten and optimized brazing techniques. The nickel-plated surface forms a protective barrier against oxidation, ensuring long-term reliability even in harsh conditions. Additionally, our design mitigates vibration-induced failures by incorporating robust mechanical structures and precise dimensional control.
Global Trust: Renowned for our unwavering commitment to quality and customer satisfaction, we have earned the trust of leading motorcycle OEMs and smart home brands worldwide. Our consistent delivery of high-quality tungsten contacts, backed by stringent quality control processes and comprehensive testing, has solidified our reputation as a reliable partner. We pride ourselves on our responsive service, with dedicated teams ready to address customer needs promptly and efficiently.
