Any ideas of where I might find these? He will be testing corrosive effects of salt water and the samples used have to be the same size. We only need 3 or 4 different metals.

Your problem might be worse than u think. I went to a special corrosion school. The purity of your test materials become very important. If u have a test piece that has a small impurity in it one of the metals will become the Cathode which will not corrode and the other is the anode and will corrode . This can cause a small hole very quickly.
If u have a pipe in the ground u can take a power supply and connect the the positive to the pipe and take a stainless rod and drive it in the ground and the rod will try to corrode and the pipe will not.
