Ryerson’s 101 copper (oxygen-free) flat bar is used for its enhanced electrical conductivity. It is often used in the manufacturing of semiconductors, super conductors and particle accelerators. Copper 110 flat bar, known as electrolytic tough pitch (ETP) copper, is ideal for electrical conductivity and formability and is used in electrical components, telecommunication materials and wiring. Offered in a variety of edge conditions including full round edge and square edge, copper bus bar can is also available with either tin or silver plating.
