An EP catheter includes a tip electrode having a core primarily comprised of copper with an outer layer of a biocompatible metal disposed thereon exhibits appropriate electrical and thermal conduction characteristics while being cost-effective to produce. Alternatively, an inner layer of a biocompatible metal is disposed on the inside of the primarily copper core. Such a tip electrode may also be provided with irrigation lumens. Such a tip electrode could be manufactured from sheets of metal that upon extrusion would comprise the outer layer, core and optional inner layer respectively.
