Our take on the Copper Flat Bar - 3.18mm Thick (1/8") - All Widths + All Lengths

This is a C11000 electrolytic-tough-pitch copper flat bar, 3.18 mm (1/8") thick, sold in widths from 12.7 mm (1/2") up to 50.8 mm (2"). C11000 is the standard high-conductivity copper, around 100% IACS, so the same bar works as an electrical bus bar or as general fabrication stock. It suits electricians, hobby builders and small shops that need a short length in a specific width rather than a full mill run. Against hardware-store copper strip, the range of widths and the stated alloy make it easier to match a job exactly.

Questions and answers

What is C11000 copper good for?
C11000 is high-conductivity electrolytic tough pitch copper, about 100% IACS. It is the usual choice for bus bars, grounding and general electrical work, and it also conducts heat well.
Can I use this as an electrical bus bar?
Yes. The 1/8" thickness and flat section suit bus bar and grounding links. Clean the surface and use appropriate connectors and torque for a reliable joint.
How hard is it to cut and drill?
It is soft copper, so a hacksaw, angle grinder or bandsaw cuts it and standard bits drill it easily. Deburr edges and clamp it firmly, since soft copper can grab a drill bit.
Which width should I pick?
Match the width to your current rating and the space you have. Wider bar carries more current and spreads heat better; narrower bar fits tight terminals and small enclosures.
Does it come in other thicknesses?
This listing is the 3.18 mm (1/8") thickness only. Other thicknesses are separate products, so check the thickness before ordering.
Will it corrode outdoors?
Bare copper forms a brown-green patina over time. That is normal and does not stop it conducting, but clean the contact surfaces before making electrical connections.
