It's a Motor "Brush" or Pickup "Brush" (125 years ago they were copper brushes) and are normally made of a carbon materials such as graphite mixed with a hardening agent like copper dust, asbestos, or asinic.
They very in hardness, they are designed to wear, they are required to be softer than the surface they run against, such as a motor commutator or as a pickup on the side of a wheel, both of which you do NOT want to wear.

Graphite would be my guess also.

So zinc would wear down easy? Like that is on most all electrical pickups for g gauge.
