Cerrosafe alloy is used by gunsmiths for making a reference casting of the chamber of a firearm. When the alloy solidifies it shrinks, allowing easy removal from the chamber. When it cools it expands back to the exact size of the chamber. The casting can then be directly measured with calipers or a micrometer to determine the dimension of the weapon's chamber, which is important for safety.

Famous quotes containing the word related:
“Perhaps it is nothingness which is real and our dream which is non-existent, but then we feel think that these musical phrases, and the notions related to the dream, are nothing too. We will die, but our hostages are the divine captives who will follow our chance. And death with them is somewhat less bitter, less inglorious, perhaps less probable.”
—Marcel Proust (1871–1922)
