COPPER FOIL
Targray is a leading North American supplier of battery-grade copper foil – a material primarily used as the current collector of the anode in lithium-ion batteries. Starting at 4μm in thickness, our Cu foil products include electrodeposited (ED) copper foils, rolled annealed (RA) foils, high-tensile alloy (HTA) foils and roll-clad foils that combine the high conductivity of copper with aluminum, tin and silver to create unique performance benefits.
Our manufacturing partners combine strict quality management practices with novel handling technologies to ensure customers are consistently receiving the best quality foils for their battery manufacturing projects. For more information about our battery-grade copper product lines, consult the table below. For purchasing inquiries, please contact us.

HIGH TENSILE ALLOY (HTA) COPPER FOIL
The growing adoption of silicon in anode materials is driving the need for stronger foils able to withstand greater stress. Our thin RA copper foil based on high-tensile alloys is designed specifically for use with with silicon-based anodes. Its increased mechanical strength and thermal stability (up to 500C) come at the expense of electrical conductivity, which is somewhat reduced.
PRODUCT SUMMARY
50-100% higher strength than pure copper.
Mechanical strength maintained at very high temperatures.
Different alloys available with distinct features.
Available as thin as 0.0008-0.020mm
Surface Options | Solvent or electrolytically degreased.
MATERIAL PROPERTIES
Ultimate tensile strength of 500 to 750 MPa.
High thermal stability of up to 500 degrees celsius.
Electrical conductivity between 40% and 86% IACS.
