It could be a anode of zinc, zinc has a hardness scale of 2.5, aluminum is 2.5 to 3, steel is 4 to 4.5.

Also zinc is about 3 times heavier than aluminum, and very close to the weight of steel, only a little bit lighter.

That's my best guess, also thinking zinc because it's not showing any signs of rust.

Hard to get a good look at the piece because of the focus.
