To All,
I was taught in Engineering to use a standard for any product I am going to use. Calulate the forces on a joint. At least estimated to loads both in Tension and in Shear.
You will notice in this standard I picked for blind rivets that have an Aluminum body and a steel mandrel the Tensile Strength and Shear Stengths are very close to being equal. Of course as the dimameter increases the strength will increase.

Have fun!
Proper installation is very important in any rivet application or joint.
