  • What Is Malleability in Metal?

    The crystal structure of harder metals, such as antimony and bismuth, makes it more difficult to press atoms into new positions without breaking. This is because the rows of atoms in the metal don't line-up. In other words, more grain boundaries exist, which are areas where atoms are not as strongly connected. Metals tend to fracture at these
