What is the difference between Silver Rivet Contact and Tungsten Rivets?

Silver Rivet Contact and Tungsten Rivets are significantly different in many aspects, and each has unique advantages that enable them to perform well in different application scenarios. The following is a detailed comparison of the two:

Ⅰ. Definition and Use

1. Silver Rivet Contact

Definition: Silver rivet contact is an electrical contact material that uses silver as the main component and is usually fixed by riveting.

Use: Due to its good conductivity, thermal stability and corrosion resistance, silver rivet contacts are widely used in power equipment such as relays, contactors, load switches, electrical switches, and instruments and meters to achieve circuit connection, load and disconnection functions.

2. Tungsten Rivets

Definition: Tungsten rivets are rivets made of refractory metal tungsten as the main component.
Uses: Tungsten rivets are usually used in places that need to withstand high temperature, high pressure or high stress environments, such as aerospace, military equipment and high-end manufacturing, due to their high melting point, high density, high strength and high hardness.

Ⅱ. Physical and chemical properties

1.Silver Rivet Contact

Conductivity: Silver is an excellent conductor with low contact resistance and stable conductivity.

Thermal stability: Silver has a low thermal expansion coefficient and can maintain stable performance over a wide temperature range.

Corrosion resistance: Silver exhibits good corrosion resistance in a variety of environments.

2.Tungsten Rivets

Melting point: Tungsten has an extremely high melting point, one of the highest known metals, so tungsten rivets can maintain structural stability in high temperature environments.

Density and hardness: Tungsten has a high density and high hardness, which makes tungsten rivets have excellent mechanical strength and wear resistance.

Thermal expansion coefficient: Tungsten has a relatively small thermal expansion coefficient, which helps tungsten rivets maintain dimensional stability at high temperatures.

Ⅲ. Price and application scope

1. Price

Silver rivet contacts are relatively expensive because they use precious metal silver.

The cost of tungsten rivets is relatively low because although tungsten is a rare metal, its content in the earth's crust is relatively abundant, and its mining and processing technology is relatively mature.

2. Application scope

Silver rivet contacts are mainly used in power equipment and electronic components, where high requirements for conductivity and stability are required.

Tungsten rivets are widely used in industrial fields that need to withstand high temperature, high pressure or high stress environments.

In summary, Silver Rivet Contact and Tungsten Rivets each have unique advantages, and the choice of which material depends on the specific application scenario and requirements. There are significant differences in definition and use, physical and chemical properties, price and application scope. In situations where high conductivity, high thermal stability and corrosion resistance are required, silver rivet contacts are a better choice; in situations where high temperature, high pressure or high stress environments are required, tungsten rivets are more advantageous.
