Not knowing exactly what is in alkaline batteries, I don't know what the stuff is, but it is corrosion due to the differing electrochemical half-cell potentials (redox potentials) of the various materials involved -- the spring contacts and the battery (cell) materials.
I am sure Google will turn up the materials involved in the electrochemical cell inside an alkaline battery and I know one may find a table of half-cell potentials for many, many common materials.
all the best,
