Metal­lic zinc is a sil­very-gray met­al with a melt­ing tem­per­a­ture of around 419.5 °C (787.2 de­grees °F). At 100 °C (or 212 °F), the met­al is mal­leable. It is rather brit­tle at room tem­per­a­ture. Metal­lic zinc is ob­tained from en­riched ore (usu­al­ly spha­lerite ZnS is used for these pur­pos­es).
