General Specifications
Copper Square Bar Grades
We stock copper square bar in multiple alloy grades. Select the right alloy for your conductivity and fabrication requirements.
Copper 102 – Oxygen-Free Square Bar
Premium oxygen-free copper square bar with 100% IACS conductivity. Free from hydrogen embrittlement, ideal for brazing and welding operations.
Copper 110 – ETP Square Bar
The most widely used commercial copper square bar. Copper 110 ETP provides 100% IACS conductivity with excellent workability for general-purpose electrical and fabrication applications.
Copper 110 — ETP
Electrolytic Tough Pitch (UNS C11000)
The world's most widely used copper alloy. Copper 110 delivers 101% IACS electrical conductivity with excellent formability, solderability, and corrosion resistance. It is the industry standard for busbars, electrical connectors, roofing, and virtually any application requiring high-purity copper.
