I suspect the rod I picked up was also a zinc alloy, not aluminum. It was
very hard to file and from my experience with how poorly it bonded to
aluminum, I expect it would break loose from the threads before it would
allow itself to be cut. This stuff also required no flux, which makes me
suspicious. The Muggy Weld material needs flux.
