With diameters from 2 mm to 6 mm, this small copper round bar sits at the fine end of the bar range, where buyers need a rigid, conductive, easy-to-machine solid rod rather than flexible wire. It is widely chosen for small pins and shafts, electrical connectors and terminals, model and hardware making, jewelry and metal crafts, rivets and fasteners, and light conductive or grounding links across the United States.\u003c\/p\u003e\n\n\u003cp\u003eEvery length of small pure copper 110 round bar is solid (not hollow, not stranded), supplied straight, and available in both millimeters and inch fractions so it matches metric drawings and US workshop measurements alike.

In \u003cstrong\u003eround bar (round rod)\u003c\/strong\u003e form it has a constant circular cross-section along its full length. The 2–6 mm range is classified as \u003cstrong\u003esmall round bar\u003c\/strong\u003e: thick enough to stay rigid and machine like bar stock, yet small enough for delicate parts where larger copper rod would be oversized.\u003c\/p\u003e\n\u003cp\u003eUS buyers use the words \u003cem\u003ebar\u003c\/em\u003e and \u003cem\u003erod\u003c\/em\u003e interchangeably for this product — searching for both “small copper round bar” and “thin copper rod” leads to the same solid round stock.\u003c\/p\u003e\n\n\u003ch3\u003eAvailable Diameters: 2mm to 6mm\u003c\/h3\u003e\n\u003cp\u003eThe table below shows the standard small pure copper 110 round bar diameters with approximate inch equivalents.
