Zirconium and aluminum at 10% to what other metsal or is it ten percent Zr to 90 Al? Sounds like a high tech alloy.
It's a shit alloy. 5% works much better and faster. 10% tends to clump and sludge and form oxides too quickly. But some asshole are too stupid to know the diff.
It's alloyed with Al and used in the nuclear feild.
