Car Horn Tungsten Contact Rivets: Excellent Performance And Wide Applications

Car Horn Tungsten Contact Rivets, used in switches to connect or disconnect circuits, feature a smooth, crack- and scratch-free surface, high hardness, wear resistance, arc erosion resistance, excellent impact resistance, strong current interruption capability, low thermal expansion coefficient, and low vapor pressure. They are widely used in various fields, including industry, agriculture, science and technology, and defense.

The rod of Tungsten Contacts should be free of cracks and scratches, with a smooth surface; fine and uniform grain size and short fibers; excellent straightness, concentricity, and roundness; high hardness and excellent impact toughness; low vapor pressure, slow evaporation rate, low thermal expansion coefficient, and excellent and stable arc resistance.

Tungsten for Tungsten Rivet is a nonferrous metal and an important strategic metal. Tungsten ore was called "heavy stone" in ancient times. Tungsten accounts for 0.001% of the Earth's crust. Twenty types of tungsten-containing minerals have been discovered. Tungsten deposits are generally formed in conjunction with the activity of granitic magma. After smelting, tungsten is a silvery-white, shiny metal with an extremely high melting point and great hardness.

Tungsten is used as an electrical contact or contact material. It is resistant to arc erosion; has good resistance to melting; the metal surface evaporates due to the electric heating effect, transfers and consumes less; has a strong ability to interrupt current; and has good wear resistance and impact resistance. Compared with other metal or alloy materials, it is cheap, so Tungsten Contact Rivets and tungsten discs are widely used in various fields of industry, agriculture, science and technology and national defense.

1. Used in automotive electrical appliances

(1) Car horns: Electrical Tungsten Contact Rivets can be placed in the air for a long time without being oxidized, ensuring that car horns do not fail within a certain range.

(2) Car distributor: a component in the gasoline engine ignition system that transmits high-voltage current to the spark plugs of each cylinder in a timely manner according to the cylinder ignition sequence. 

(3) Automobile voltage regulator: a key component of automobile generator.

(4) Automobile alarm: Used for automobile alarms with sound and light on various trucks and engineering vehicles (such as reversing alarms).

2. Used in motorcycle engine ignition devices

Although contactless electronic ignition devices have been around for nearly sixty years, and technology and performance have been continuously improved, Tungsten Rivets are still widely used in (cheap) motorcycle engine ignition devices due to their advantages such as arc erosion resistance, simple structure, low cost and easy maintenance and replacement.

Among many applications, Car Horn Tungsten Contact Rivets are our star products. This product is made of high-quality tungsten material and is precision-machined to ensure a smooth surface without cracks or scratches, high hardness, wear resistance, arc erosion resistance, good impact resistance, strong current interruption capability, low thermal expansion coefficient and low vapor pressure. It can not only effectively extend the service life of car horns, but also maintain stable performance in various harsh environments. It is an indispensable high-quality component in the field of automotive electrical appliances.
