Copper 110 Supply
C11000 Electrolytic Tough Pitch (ETP) Copper
Copper 110 is the most widely used commercial copper alloy. With 100% IACS electrical conductivity, excellent corrosion resistance, and availability in virtually every wrought form, it is the industry standard for electrical, architectural, and industrial applications.
About Copper 110 (C11000)
Copper 110 (C11000) is Electrolytic Tough Pitch (ETP) copper — the most widely used commercial copper alloy. With a minimum 99.90% copper content and 100% IACS electrical conductivity, it is second only to silver in conductivity.
Maverick Metals supplies Copper 110 in a comprehensive range of product forms — round bar, flat bar, sheet, rod, strip, foil, wire, and tube. Every product is manufactured to ASTM specifications and ships with full mill test reports (MTRs).
