I hear bad things about tanks made of black iron. I would guess that a magnet will tell you whether or not a tank is aluminum, but if the magnet sticks, is there a way to figure out if it is steel or black iron?

Good inspection ports , proper baffels and a water sump are part of how well the tank is built.
