Tungsten Contact Rivet
Tungsten Contact Rivet Description
Rivets are mainly used to connect two nail-shaped parts with a cap at one end and a pass hole. Tungsten Contact Rivet is a solid rivet made of tungsten by powder metallurgy process. Due to its excellent physical and chemical properties, it is often used in relays, high-voltage switches various automatic switches, auto parts, and other products. During the use of electrical equipment, contacts will experience frequent switching operations, and tungsten contacts can maintain good contact performance for a long time, which can reduce maintenance and replacement costs, and extend the service life of electronic devices.
Processing technology
Our company often uses powder metallurgy processes for production, the contacts have been mixed powder, ball milling, heat treatment, high-temperature sintering, coating treatment, and finally quality control. The contacts produced by it have high purity, uniform internal structure, high dimensional accuracy, and durability.
Characteristics
- High density, high strength, high melting point, low evaporation rate
- Resistance to arc erosion, high conductivity, suitable for efficient current transmission
- Excellent corrosion resistance and oxidation resistance, it can maintain stable contact performance in various chemical environments
- Good high-temperature stability, and long service life, to ensure the safe operation of electrical equipment
Application
Tungsten Contact Rivet is most commonly used in AC contactors, electromagnetic relays, all kinds of high and low-voltage switches, machine tool breakers, or automotive electrical equipment.
