Thickness:0.1~3mm Pure Copper Strip for electrical component, Lamp head, battery caps
Pure Copper Foil C11000/Cu-ETP Strip
C11000 - also known as Electrolytic-Tough-Pitch (ETP). This is the most common copper. It is universal for electrical applications. ETP has a minimum conductivity rating of 100% IACS and is required to be 99.9% pure. It has 0.02% to 0.04% oxygen content (typical). Most ETP sold today will meet or exceed the 101% IACS specification. As with OF copper, silver (Ag) content is counted as copper (Cu) for purity purposes.
Standard: JIS C1100, ASTM C11000
