The purpose of Contact Rivets is to join two components together. They can be recognized as buttons or small pieces of screws without threads. These rivets are categorized into various types, such as solid contact rivets and composite contact rivets. This article describes all about the making of contact rivets.

Generally, copper is used for the making of contact rivets. Some small pieces of raw ductile contact materials are placed into an automatic cold heading machine to alter these materials into rivets. During this stage, the rivet head is produced by hammering and pressing. Here the rivet head produced can be flat, spherical, domed, or pointed that perfectly fits the rivet’s final application.

Bimetal rivets are a special type of composite contact rivets. Basically, these contact rivets are made from a combination of two different metal materials. These two metals are firmly bound around each other. This makes a composite contact rivet. Different metal materials that are used to make the bimetal rivets may include, platinum, iron, silver-based alloys, tin, or even gold. This blend of the metal materials is executed basically by the same technique of cold pressing as well.

The choice of metal materials depends upon the customer’s requirement or requirement of the task. The general configuration or layout of the silver bimetal contact rivets is very extensive. These rivets are highly versatile in the choice of strength, contact materials, physical properties, or surface treatment, etc. As the two metals are combined into one, the bimetal rivets are known to produce better characteristics to fit the application.
