yes
steel aluminum brass copper nickel iron chromium
I guess Al (aluminium), Ni (nickel) and Co (cobalt).
Al(s) | Al3+(aq) Ni2+(aq) | Ni(s)
the nickel metal
The nickel metal(apex)
The voltage of a galvanic cell is the difference between the half cell potentials for the two reactions. For silver and nickel, this is about 1 volt.

1.05 V
Galvanic corrosion occurs when the two meet (especially when water is present) - use a barrier lubricant (Tefgel or anti-seize) or plate the screws with Nickel/Teflon or Cadmium.
The Nickle Metal
Most do not have nickel.
Hydrochloric acid will react with Aluminum to form Aluminum Chloride (AlCl3) but not with Nickel.
