Tungsten Contacts
Tungsten Contacts: Built for Extreme Arcing
Expertly manufactured W-Fe and W-Cu alloy contacts designed to survive 3410°C melting points and high-frequency electrical stress.
Why Choose Tungsten for Electrical Contacts?
While silver is the king of conductivity, Tungsten (W) is the king of endurance. At CD Silver (cdsilver.com), we manufacture tungsten contacts for applications where silver would simply melt or vaporize. With a hardness unmatched by any other contact metal, tungsten resists mechanical wear and material transfer in high-speed sparking environments.

The Engineering Spectrum of Tungsten Alloys
Pure tungsten is brittle and difficult to weld. To optimize performance, we specialize in two primary alloy structures:
1. W-Fe (Tungsten-Iron) Contacts
Commonly used in automotive horns and buzzers. The addition of iron increases the toughness of the contact, preventing the tungsten from cracking under the millions of high-frequency mechanical impacts required in signal devices.
2. W-Cu (Tungsten-Copper) Alloys
These are "pseudo-alloys" that combine the heat resistance of tungsten with the conductivity of copper. They are the standard for high-voltage circuit breakers and EDM electrodes, where electrical arcing is constant and intense.

Precision Manufacturing at CD Silver
Our tungsten contacts are produced through advanced powder metallurgy and precision grinding. Whether you need a W-Fe rivet with a specific head geometry or a W-Cu tip for brazing, we ensure oxygen-free environments during production to prevent surface oxidation, maintaining the lowest possible contact resistance for a tungsten surface.
