Flat Tungsten Contact Points for Motorcycle Horn are formed by brazing (welding/soldering) tungsten disc with Copper Rivet or Mild Steel Rivet. The Flat Head Rivets are made according to customer specifications and requirements. The Tungsten Copper Electrical Contact are plated by pure nickel to make it corrosion resistant. Tungsten Contact for Motorcycle Horn are widely used in high frequency make and break applications such as automobile horns, relays and distributor point.
What’s the Tungsten Contacts of Electrical Appliances?
As far as most electrical equipment is concerned, they use high-purity tungsten contacts as contact points, mainly because the Tungsten Contacts for Electrical Appliances have a high melting point, a small evaporation rate, and good electrical and thermal conductivity. Features. Tungsten Point Contact made with metal tungsten have a longer cycle life than conventional contacts, while ensuring good circuit board contact.
At present, common control electrical products such as AC contactors, electromagnetic relays, electrical switches and air switches contain electrical contacts, and Electric contacts are one of the most important components of these products. The reliability and service life of a product largely depend on the contact performance, which is affected by factors such as the contact material, load type, contact pressure, operating frequency, and use environment. When these factors cannot meet the working requirements, there will be problems such as electrochemical corrosion of contacts, welding between contacts, contact wear, and increase in contact resistance, which will lead to unreliable operation, functional failure and even potential safety hazards.
In the energized state, if the current to open the circuit exceeds a certain limit, or if the voltage across the contact gap after disconnection exceeds a certain limit, a yes will occur in the contact gap. Under the action of a strong electric field, the gas between the contacts will discharge, and sparks and strong light will be generated and emitted with the increase of temperature. The arc will corrode the metal surface of the contact, shorten the service life of the electrical appliance, prolong the breaking time of the circuit, and cause the contact of the contact to fail. In severe cases, it can also lead to fire accidents.
Today, in order to further improve the overall quality of electrical equipment contact points, most manufacturers use metal pure tungsten to manufacture electrical contacts.
