Since most alkaline batteries have nickel plated containers, a nickel coating for the metal contacts is preferable.
The use of similar materials removes the possibility of galvanic corrosion and aids in wear resistance.
Nickel will also tend to wipe and aid in breaking down the oxide that can form on the battery metal contact surface.
In addition, a nickel coating will provide general corrosion resistance and is an excellent conductor of electricity.
