    Definition of CopperOccurrenceUses AreaAssociationDistributionReferencesIn its free-occurring metallic state,copper was probably the first metal to be used by humans. Neolithic people arebelieved to have used copper as a substitute for stone by 8000 BCE. Around 4000BCE, Egyptians cast copper in molds. By 3500 BCE, copper began to be alloyedwith tin to produce bronze. Copper is opaque, bright, and metallic salmon pinkon freshly broken surfaces but soon turns dull brown. Copper crystals areuncommon, but when formed are either cubic or dodecahedral, often arranged inbranching aggregates. Most copper is fo
