Products Description
Horn Contact Wolfram is a high-performance electrical contact component specially designed for transportation equipment such as cars and motorcycles, as well as industrial electrical scenarios. It is made by combining tungsten discs with iron rivets through a brazing process and then nickel-plated to a thickness of 3-5 μm. It is widely applicable to core scenarios such as battery connectors, motor controllers, frequency converters, servo drives, contactors, smart home relays, and medical instrument precision switches. As a key component for electrical conduction and on-off control, it ensures the stable operation of equipment under high-frequency on-off and large current impact conditions, and is a core basic component in high-end home appliances, medical communication equipment, industrial automation, and new energy vehicles.
Product Details and Features
Tungsten Contacts
Manufactured through powder metallurgy process, they have a uniform structure with no internal defects such as pores or cracks, ensuring stable conduction under extreme current conditions.
Iron rivet base
Made of low-carbon steel, it has excellent mechanical strength and magnetic permeability, making it suitable for the automated riveting assembly of Tungsten Bimetal Contact Point for Automotive Horn.
Welding interface
Tungsten Contact Rivets are manufactured to be free of oxidation and welding flaws. The resulting interface layer is thin and dense, creating a physical guarantee that ensures stable electrical performance transmission.
Surface treatment
The nickel coating is smooth and dense, without peeling or exposing the base layer. This ensures the long-term stability of the product during storage and use. This is precisely our quality commitment for Tungsten Contact for Motorcycle Horn and for other application scenarios as well.
Material properties and advantages
| High resistance to welding | The high melting point makes it less likely to be welded to the opposite Tungsten Brazed Rivets due to the heat generated by the large current at the instant of closure. |
| High arc erosion resistance | When breaking the circuit, tungsten can effectively resist the high-temperature erosion of the arc, maintaining the integrity of the AC Contactor Tungsten Contacts' shape. |
| Low contact resistance | The surface oxide film is prone to breakage under pressure, ensuring stable contact resistance of the Tungsten Rivet during long-term use. |
Manufacturing process
Welding contact preparation: Tungsten Point Contact is manufactured through a sequence of powder metallurgy forming, high-temperature sintering, and precision stamping. This process achieves the required dimensional accuracy while guaranteeing surface flatness and uniformity in conductivity.
Iron rivet processing: Low-carbon steel is first formed into a stepped rivet structure using cold heading, establishing the necessary foundation for the brazing and assembly operations of the Motorcycle Horn Tungsten Rivet that follow.
Brazing composite: In a protective atmosphere furnace, silver-based brazing filler precisely welds the contact to the iron rivet, creating a high-strength integrated Furnace Brazing Tungsten Contact structure that eliminates interface voids and delamination.
Nickel plating treatment: After degreasing and acid washing, the surface of the Tungsten Contacts product is electroplated with a 3-5 μm nickel layer to enhance corrosion resistance and conductivity.
Finishing and inspection: After deburring and size calibration, through optical inspection, resistance testing, and combined strength testing, the Tungsten Bimetal Contact Point for Automotive Horn product is ensured to meet technical standards.
