Copper Alloy 110/C110/C11000 Electrolytic Tough Pitch (ETP)
Copper Alloy 110/C110/C1100 Electrolytic Tough Pitch (ETP)  is a very pure alloy of copper
(99.9% min. cu). It is a versatile alloy because of its resistance to corrosion, high electrical and thermal
conductivity, and its aesthetic quality. It is used for a variety of projects and applications including
construction, DIY, arts and craft projects, rfi shielding, manufacturing, electrical applications, research and
development and much more.
