Aluminum vs. Stainless Steel Blind Rivets: A Buyer’s Guide

Aluminum and stainless steel are common blind rivet materials, but the material name alone is not enough to specify an order. Buyers should compare the complete rivet specification and the requirements of the joint.

Specify the Body and Mandrel Separately

A blind rivet has a body and a mandrel. An aluminum body may be paired with a steel, aluminum or stainless steel mandrel. Likewise, a stainless steel body does not automatically mean that the mandrel is the same material. Ask for both materials and any required grades in the quotation.

Compare the Requirements, Not Just the Material Label

Aluminum is often considered when weight matters. Stainless steel may be considered where the specification calls for its material properties or corrosion resistance. Neither label guarantees that a particular rivet is suitable for every application.

• Joint materials: identify the sheets or components being joined and check material compatibility.

• Service environment: describe indoor or outdoor exposure, moisture, chemicals or other relevant conditions.

• Required performance: compare the published tensile and shear values for the exact rivet, rather than assuming one material is always stronger.

• Installation: confirm the tool capacity, nosepiece and access available for setting the rivet.

Keep the Other Details Consistent

When comparing quotations, use the same diameter, length, grip range, head style and rivet design. A price comparison between different specifications may not represent a like-for-like choice. The required grade, finish and packaging should also be stated clearly.

What Should You Send a Supplier?

Provide the body and mandrel materials, product code or drawing, dimensions, joint thickness and quantity. If the application has specific corrosion or load requirements, include them before requesting a recommendation.
