Small Pure Copper 110 Round Bar Rod 2–6mm Diameter

Small Pure Copper 110 Round Bar & Rod, 2–6mm Diameter

Small pure copper 110 round bar — also called thin copper rod or small-diameter solid copper round bar — is a solid, straight-length copper rod drawn from 99.9% pure copper 110. 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.

Every 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. Stock diameters can be ordered as standard lengths or cut exactly to the length your project requires.

What Is Small Pure Copper 110 Round Bar?

Pure copper 110 is a commercial-grade 99.9% pure copper known for high electrical and thermal conductivity, natural atmospheric corrosion resistance, and straightforward machining, turning, drilling, bending, and soldering. In round bar (round rod) form it has a constant circular cross-section along its full length. The 2–6 mm range is classified as small round bar: thick enough to stay rigid and machine like bar stock, yet small enough for delicate parts where larger copper rod would be oversized.

US buyers use the words bar and rod interchangeably for this product — searching for both “small copper round bar” and “thin copper rod” leads to the same solid round stock.

Available Diameters: 2mm to 6mm

The table below shows the standard small pure copper 110 round bar diameters with approximate inch equivalents. Select your diameter as the product variant, then choose your required length.

Diameters are listed in millimeters with inch equivalents; set your Shopify variants to the exact diameters you stock from this range. Lengths above 6 mm belong to the medium (8–25mm) and large (26–100mm) pure copper 110 round bar ranges.

Key Properties of Pure Copper 110 Small Round Bar

Why Buy Small Copper Rod in the 2–6mm Range

• Rigid where wire is not — thin copper wire bends under its own load, while 2–6mm round bar holds shape for pins, posts, and frames.
• Right size for small turned parts — connectors, contact pins, standoffs, and rivet blanks machine efficiently from small-diameter rod.
• High conductivity in a compact section — suits signal and low-current links, sensor leads, and compact grounding jumpers.
• Metric and inch friendly — diameters and lengths are easy to match to both imported drawings and US inch-based builds.
• No minimum waste — order cut lengths instead of full stock sticks for short-run or prototype work.

Common Applications

Small pure copper 110 round bar and thin copper rod are widely used for electrical connector pins and sockets, terminals and lugs, contact pins and probe tips, standoffs and spacers, small shafts, axles and spindles, rivet and fastener blanks, hinge pins, grounding jumpers and bonding links, busbar taps, switch and relay components, welding and electrode tips, coil leads, antenna elements, RC and model hardware, jewelry pins and findings, stained-glass and metal-craft frames, garden and plant supports, and general CNC turning, Swiss-machining, and fabrication of small copper parts.

Custom Cut Lengths

Small pure copper 110 round bar can be supplied in standard straight lengths or cut to the exact length your drawing or assembly calls for, in millimeters or inches. Multiple identical cut pieces can be produced from the same 2–6mm diameter rod, so small bars can be ordered ready to use rather than as full stock lengths. Diameter is chosen from the variant list; length is specified when ordering.
