Product Features

Core Features

Excellent Wear Resistance

The hardness of Tungsten Contact Rivets, combined with the ductility of copper, results in a material with superior wear resistance, reducing the rate of erosion and prolonging the life of the contact.

Low Bouncing Rate

The use of Tungsten Point Contact in the contact material helps to reduce the bouncing rate during switching, which is essential for reliable and consistent electrical connections.

Compatibility with Brazing and Soldering

These Tungsten Brazed Rivets are compatible with brazing and soldering processes, which allows for versatile assembly methods in the manufacturing of electrical devices.

Long Service Life

Due to the combination of the aforementioned features, Tungsten Copper Electrical Contacts typically have a longer service life compared to contacts made from other materials.

Manufacturing Process

Powder Metallurgy	The manufacturing of Tungsten Copper Electrical Contacts often begins with powder metallurgy, where tungsten and copper powders are mixed and compacted under high pressure.
Sintering	The compacted powder is then sintered at high temperatures to create a solid, dense material with the desired properties.
Cold Heading	For certain applications, such as Car Horn Tungsten Contact Rivets, the sintered material is subjected to cold heading, a process that shapes the material into the final form using cold forging techniques.
Brazing	In the case of Tungsten Brazed Rivets, the tungsten and copper components are joined together using a brazing process that involves the use of a filler metal with a lower melting point than the base materials.
Machining and Finishing	Once the basic shapes are formed, the contacts undergo precision machining to achieve the exact dimensions and surface finishes required for their specific applications.
