Pure Copper

WILKO stock superior high purity copper bars with a grading of 99.98%. With the market standard at 99.9%, these WILKO products are a notch above the rest. Our busbar and rods are available in both high conductivity electrolytic tough pitch (ETP) and high conductivity Oxygen Free Copper (OFC).

Both classes achieve an electrical conductivity of approximately 101% IACS (versus conventional busbar standards of below 98.0% ICAS) and are produced from grade "A" 99.99% LME registered brand of pure copper cathodes to meet various international standards.

WILKO offers copper busbar and rods which have the right conductivity, right formability, right flatness to become the right provider of choice for solutions to most electrical applications.
