Brass Round Tube — Precision Hollow Tubing for DIY, Model Making & Fabrication

Whether you're building a custom instrument housing, fabricating a small-scale structural frame, or sourcing stock for a precision hobby project, finding brass round tube in the exact outer diameter and wall thickness you need — without ordering a full industrial run — is frustrating. These brass round tubes are stocked in a wide range of OD and wall thickness combinations so you can order exactly what your project calls for, one piece at a time.

Each tube is a hollow round brass section, 300mm (≈11.8") in length. Outer diameters range from 10mm (≈3/8") to 19mm (≈3/4"), and wall thickness options span 0.2mm to 3mm — giving you inner diameters from as tight as 4mm up to 18mm depending on the combination selected. Material is brass (copper-zinc alloy), which machines, solders, and finishes readily.

Typical applications include scale model framing and telescoping tube assemblies, DIY lamp and furniture hardware, scientific instrument components, jewelry and craft fabrication, and plumbing or pneumatic prototyping where a brass hollow round tube with precise metric OD is required.

📐 Metric sizing: OD dimensions follow standard metric increments (10–19mm). Compatible with most metric compression fittings, sleeves, and couplings — verify your fitting's bore against the OD/ID listed in the variant selector before ordering.

✅ Key Features of These Brass Round Tubes

  • 🔩Wide Size Matrix — OD from 10mm (≈3/8") to 19mm (≈3/4") paired with wall thicknesses from 0.2mm to 3mm, covering thin-wall precision tubing through heavy-wall structural stock in a single listing.
  • ⚙️Machinable Brass Alloy — Copper-zinc brass cuts cleanly with a pipe cutter or hacksaw, drills without burring, and threads readily — making it a go-to material for brass hollow round tube applications in both hobby and light industrial work.
  • 🔥Solderable & Brazeable — Joins easily with standard lead-free or silver solder, enabling clean, strong connections for instrument housings, decorative hardware, and fluid-carrying prototypes.
  • 🌧️Natural Corrosion Resistance — Brass resists oxidation in indoor and moderately humid environments, making it suitable for exposed decorative components and fittings without requiring a protective coating in most indoor settings.
  • 📏Consistent 300mm Cut Length — Each piece is 300mm (≈11.8") long — a practical stock length for model making, lamp fabrication, and prototyping that minimizes waste when cutting to final dimension.
  • 🎯Precise OD/ID Tolerances — Outer and inner diameters are specified per variant, so you can select telescoping tube pairs or confirm clearance fits without guesswork — critical for metric brass tube applications in precision assemblies.

⚠️ Confirm your fit before ordering: Inner diameter = OD − (2 × wall thickness). If you need a specific bore size, calculate accordingly or contact us to confirm. Tolerances may vary slightly by size — contact us for tolerance specs on critical-fit applications.

❓ Frequently Asked Questions

How do I choose the right OD and wall thickness for my project?

Start with the outer diameter (OD) that fits your application — for example, a 12mm OD tube (≈15/32", roughly 1/2") is commonly used in model frames and instrument housings. Then select wall thickness based on load: thinner walls (0.2–0.5mm) suit lightweight decorative or precision work, while thicker walls (1–3mm) are better for structural or pressure-bearing uses. The inner diameter (ID) equals OD minus twice the wall thickness — for example, a 12mm OD / 1mm wall tube has a 10mm ID (≈3/8").

What is the tensile strength of these brass tubes?

Brass (typically a C26000-equivalent or similar alloy) generally has a tensile strength of around 300–500 MPa depending on temper and alloy composition. For structural or pressure-rated applications, contact us to confirm the specific alloy grade before ordering.

Can these brass tubes be used outdoors or in humid environments?

Brass is naturally corrosion-resistant and performs well in moderately humid or marine-adjacent environments. For prolonged outdoor exposure, applying a clear lacquer or sealant is generally recommended to prevent tarnishing and surface oxidation over time.

Are these tubes compatible with standard metric fittings and couplings?

Yes — the OD dimensions follow standard metric sizing (10mm, 11mm, 12mm, etc.), making them compatible with most metric compression fittings, couplings, and sleeves. Always verify the bore ID of your fitting against the OD listed in the variant options to confirm a proper fit.

Can I cut, drill, or solder these brass tubes?

Yes. Brass cuts cleanly with a pipe cutter, hacksaw, or rotary tool. It drills without excessive burring and is highly solderable — compatible with standard lead-free or silver solder. Deburr cut ends before assembly for a clean, safe fit. Brass can also be brazed for higher-strength joints.

Which wall thickness should I choose for model making vs. structural use?

For model making, jewelry, or decorative crafts, wall thicknesses of 0.2–0.5mm are typically sufficient and keep weight low. For structural frames, instrument housings, or applications with mechanical stress, 1–3mm walls provide meaningfully greater rigidity and load capacity. When in doubt, go one step thicker — it's easier to remove material than to add it.

What is the length of each tube, and can I order custom lengths?

Each tube is 300mm (≈11.8") long. Custom lengths are not currently available through the standard listing. Contact us if you need a different cut length and we will advise on available options.

Can these tubes be used for telescoping assemblies?

Yes — this is one of the most common uses for precision brass round tubing. To create a telescoping fit, select an inner tube whose OD is close to (but slightly smaller than) the ID of the outer tube. For example, a 10mm OD / 0.5mm wall tube (9mm ID) can typically accept a tube with an OD of approximately 8.5–9mm. Always verify clearance with your specific variant combination before ordering multiples.
