Because of its high zinc content, brass suffers from a peculiar type of corrosion known as dezincification; when this happens, the zinc sacrificially corrodes from the alloy, leaving behind a porous, weak copper structure that deceptively retains its shape yet is devoid of most of its original rigidity.
