I have some old trophy round metals how do i find out if there alumium or brass?
A given unit of brass is much heavier than the same unit of aluminumIf it's gold-colored, find an inconspicuous area and put a scratch in itIf you see silver color in the scratch, it's probably anodized aluminumIf you see the same gold color in the scratch it's probably brassMy guess is that it's probably brass.
