WebJun 26, 2003 · A Closer Look. Remember there are three basic crystalline structures favored by metals: body-centered cubic (BCC), face-centered cubic (FCC), and hexagonal close packed (HCP). Pure iron is one metal that changes from one of these crystalline structures to another while remaining solid. It's BCC at temperatures up to 1,670 degrees F. WebMost metals are close packed - that is, they fit as many atoms as possible into the available volume. Each atom in the structure has 12 touching neighbours. Such a metal is described as 12-co-ordinated. Each atom has 6 other atoms touching it in each layer.
