Ga Out - Lu In
We are sorry to report that the gallium-copper alloy experiment failed after it looked hopeful we'd be able to supply these unique ingots. We've ruled out pure gallium ingots given the very low melting point and HazMat shipping issues. We've decided instead to put these resources into lutetium, one of the rarest of the rare earths. We hope to have our lutetium ingots available by the end of this year.
