ETP Copper (Electrolytic Tough Pitch) is the most widely used copper grade with universal use in electronic applications. ETP copper has extremely high electrical conductivity, surpassed only by pure silver and it has excellent tensile, solderability and corrosion characteristics, making it the primary choice for applications requiring lower resistance.
