Metel coch yw copr sy'n gynhwysyn pres ac efydd. Mae e'n elfen gemegol yn y tabl cyfnodol ac iddo'r symbol Cu a'r rhif atomig 29.
Yn ei ffurf bur, mae'n dargludo trydan yn dda. Oherwydd hyn fe'i ddefnyddir yn aml mewn systemau trydan. Gwneir defnydd sylweddol o gopr mewn electroneg, gan ei fod yn dargludo gwres a thrydan yn dda.
