Automobile Step Rivets material
Automotive rivets are available in a variety of materials and material combinations. A material combination means that one material is used for the body and another material is used for the mandrel. The type of material you are working with will help determine the type of rivet material you choose. Common rivet material combinations and their respective uses are listed below:

Aluminum/Aluminum: For use with aluminum or in applications prone to rust and corrosion.
Aluminium/Steel: Similar to Aluminium/Aluminium, but stronger.
Copper: for conducting electricity
Nylon: used with plastic
Stainless Steel/Stainless Steel: Used with steel or aluminum, it has high strength and is not easy to rust and corrode.
Stainless Steel/Steel: Also used with steel or aluminum for very high strength, but is prone to rust and corrosion.
Steel/Steel: Use with steel for high strength.
Rivet Type
The two main types of rivets are open and closed.

Split rivets are designed for a wide range of applications and are the most commonly used type of rivet. The mandrel breaks near the blind side head and has a flange or countersunk head for thin gauge metals and low strength materials. When set for added strength, they also keep the end of the mandrel in the body of the rivet.

Closed-end rivets have a cup-shaped end that forms a tight seal with the adhesive material and secures the end of the mandrel within the body of the rivet for added strength. Closed end rivets are stronger than open end rivets.
