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

Finding the exact-size hollow brass tube for a scale model, RC chassis, or custom fabrication project can be frustrating when hardware stores only stock a handful of sizes. Whether you are a model railroader, a tabletop miniature builder, a jeweler, or a hands-on DIYer, having the right OD-to-ID ratio in a workable metal makes all the difference between a clean build and a compromised one.

Each listing covers a single brass round tube measuring 500mm (≈19.7″) in length, available in outer diameters from 0.8mm (≈1/32″) up to 50mm (≈1-31/32″) and wall thicknesses ranging from 0.15mm to 5mm. Select your exact OD × ID combination and wall thickness from the variant dropdowns above. The material is standard yellow brass (CuZn alloy), offering good machinability, solderability, and moderate corrosion resistance.

Typical applications include model railroad scratch-building (axle sleeves, handrails, smoke stacks), RC aircraft and drone frame tubing, architectural scale models, jewelry and craft wire forming, and general small-diameter hollow brass tube DIY projects such as custom pen blanks, lamp components, and pneumatic fittings.

ℹ️ Compatibility Note: All dimensions are metric (mm). OD and ID values are nominal; actual tolerances are typically ±0.05–0.1mm depending on wall thickness. Verify your required fit before ordering, especially for press-fit or slip-fit applications.

✅ Key Features of These Brass Round Tubes

  • 📐Wide Size Range — OD from 0.8mm to 50mm with matching ID options lets you find the exact hollow brass tube size for micro model work or larger structural DIY applications.
  • 🔩Consistent Wall Thickness — Wall options from 0.15mm to 5mm give you control over weight and rigidity; thinner walls suit lightweight model hobby craft tubing while thicker walls handle mechanical loads.
  • ✂️Easy to Cut & Machine — Brass cuts cleanly with a fine-tooth saw, rotary tool, or tube cutter and can be filed, drilled, or tapped without special tooling, making it ideal for scratch-built model railroad components.
  • 🔥Solderable & Brazeable — Brass bonds readily with rosin-core solder and silver braze, enabling strong, clean joints for RC frame tubing, custom fittings, and decorative metalwork.
  • 🛡️Moderate Corrosion Resistance — The natural zinc-copper alloy composition resists light oxidation; suitable for indoor and sheltered outdoor use in hobby and DIY brass tube projects.
  • 📦500mm Ready-to-Use Length — At 500mm (≈19.7″) per piece, each tube provides enough material for most model and craft cuts without excessive waste, shipped safely from our US warehouse.

❓ Frequently Asked Questions

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

Measure the hole or bore your tube needs to fit into, then select an OD slightly smaller than that opening. For length, 500mm (≈19.7″) is typically sufficient for most model and hobby applications — cut to size with a fine-tooth saw or tube cutter. If you need a specific fit, measure twice and add a small margin for finishing.

What wall thickness should I choose?

Thinner walls (0.15–0.3mm) are generally used for lightweight model frames and decorative applications. Thicker walls (0.5–3mm+) provide greater structural rigidity and are better suited for load-bearing or mechanical DIY uses. In most cases, a 0.5mm wall offers a good balance of strength and workability for hobby brass tube projects.

How strong is brass tubing compared to aluminum or steel?

Brass is generally stronger and denser than aluminum, making it suitable for precision mechanical parts. It is softer than steel, which makes it easier to cut, solder, and machine. For hobby and model applications, brass tubing typically provides more than adequate strength for structural and decorative uses.

Can I use this brass tube outdoors or in humid environments?

Brass has good natural corrosion resistance and generally performs well in moderately humid environments. For prolonged outdoor exposure or contact with saltwater, applying a clear lacquer or protective coating is recommended to maintain appearance and prevent tarnishing over time.

Is this tubing compatible with standard metric fittings?

These tubes are sized in metric OD and ID dimensions, making them compatible with most metric-standard fittings, connectors, and sleeves. Always verify the ID of the tube matches the OD of any insert or fitting you plan to use. For imperial fittings, check the inch equivalents listed in the variant labels.

Can I solder or braze this brass tube?

Yes. Brass is one of the most solderable metals and responds well to both soft soldering (with rosin-core solder) and silver brazing. Clean the joint area with flux before soldering for best results. This makes it ideal for model railroads, RC frames, and custom small-diameter hollow brass tube fabrication.

What is the difference between OD and ID, and which should I measure first?

OD (Outer Diameter) is the total width of the tube including the wall. ID (Inner Diameter) is the clear bore inside. If you are inserting something into the tube, match your insert's OD to the tube's ID. If the tube must fit inside something else, match the tube's OD to the opening. Always measure the critical dimension first to avoid ordering the wrong size.
