Since the usual material on a thrust bearing flange is some variation of Babbit metal, either brass or bronze will probably be more durable. I've got a good source on big military surplus brass washers at a reasonable price. I'll also investigate bronze as a possibility if the prototype engine shows any noticeable wear during dyno testing. It's not uncommon to overstress an engine or three on the test stand, working out the research and development gremlins. One of our favorite sayings was "The turns are a long way apart on a dyno, and the hills never end!"
