H62 Brass Round Tube — Precision Copper Sleeve Pipe for DIY, Modeling & Metalworking

Finding a brass tube that's cut to a consistent length, holds tight tolerances, and arrives ready to use is harder than it sounds — especially when you need a specific OD-to-wall ratio for a tight-fit sleeve or a structural spacer. Whether you're a hobbyist building scale models, a maker fabricating custom hardware, or a tradesperson needing a reliable copper-alloy sleeve, inconsistent sizing and poor surface finish waste time and money.

Each piece in this listing is an H62 brass round tube cut to 200mm (≈7.87") in length. Outer diameters range from 2mm (≈5/64") to 100mm (≈3-15/16"), with wall thicknesses from 0.5mm to 4mm — giving you a wide selection of bore sizes and rigidity levels. Tubes are available in quantities of 1, 2, 3, 5, 8, or 10 pieces per order, so you can buy exactly what your project requires without overstocking.

Typical applications include precision sleeve bearings and bushings, model railway and RC vehicle frames, decorative lamp and furniture hardware, plumbing spacers and standoffs, and custom metalworking jigs — all situations where a dimensionally consistent brass round tube for metalworking projects makes the difference between a clean result and a frustrating rework.

ℹ️ Compatibility Note: These are smooth, unthreaded tubes. OD and wall thickness determine the inner bore (ID = OD − 2 × wall). Confirm your required bore before selecting a variant. All pieces are 200mm (≈7.87") long — if you need a different length, contact us before ordering.

✅ Key Features of These H62 Brass Round Tubes

  • 🔩H62 Brass Alloy — Made from H62 copper-zinc alloy (approx. 62% Cu / 38% Zn), broadly equivalent to ASTM C27200 Yellow Brass, offering solid machinability and natural corrosion resistance for indoor and covered outdoor use.
  • 📏Wide Size Range — Outer diameters from 2mm to 100mm with wall thicknesses from 0.5mm to 4mm, covering a broad spectrum of bore sizes for precision brass sleeve tubing applications.
  • ✂️Consistent 200mm Cut Length — Each tube is cut to 200mm (≈7.87"), giving you a uniform starting length that's easy to trim further with a pipe cutter or hacksaw without excessive waste.
  • 🔧Machinable & Solderable — H62 brass cuts cleanly with standard metal tools and accepts lead-free solder and brazing, making it suitable for custom fittings, model making, and repair work.
  • 📦Flexible Quantity Options — Order 1, 2, 3, 5, 8, or 10 pieces per variant so you can match your project needs without over-buying — ideal for both one-off repairs and small production runs.
  • 🏭Smooth Exterior Finish — Tubes arrive with a smooth drawn finish typical of H62 brass round tube stock, reducing prep time for decorative hardware, lamp components, and furniture accents.

📐 Technical Specifications — H62 Brass Round Tube

Material H62 Brass (approx. 62% Cu / 38% Zn; broadly equivalent to ASTM C27200)
Tube Form Round, hollow, seamless-drawn
Outer Diameter (OD) 2mm (≈5/64") to 100mm (≈3-15/16") — see variant options
Wall Thickness 0.5mm to 4mm — see variant options
Inner Diameter (ID) ID = OD − (2 × Wall Thickness) — calculated per variant
Length 200mm (≈7.87") per piece
Quantity per Order 1, 2, 3, 5, 8, or 10 pieces — see variant options
Surface Finish Smooth drawn finish (natural brass color)
Tensile Strength (typical) Typically 330–420 MPa (varies by wall thickness and temper)
Corrosion Resistance Good in dry/indoor environments; apply lacquer for outdoor use
Machinability Good — cuts, drills, and solders with standard metal tools
Thread / Fittings Unthreaded smooth bore — contact us to confirm fit
Country of Origin China
⚠️ Size Tip: Inner diameter (ID) is not a selectable option — calculate it as OD minus twice the wall thickness. Example: OD 10mm × 1mm wall = 8mm bore. If you need a specific bore size, work backward from that number when selecting your variant.

❓ Frequently Asked Questions

How do I choose the right outer diameter and wall thickness?

Measure the inner bore you need to fill or slide over, then add twice the wall thickness to get the outer diameter. For example, if you need a 6mm bore with a 1mm wall, select OD 8mm × 1mm. When in doubt, order one size up — it's easier to sand down than to stretch brass. Wall thickness also affects rigidity: thicker walls (1.5mm–2mm) suit structural or load-bearing uses, while thinner walls (0.5mm) work well for lightweight sleeves and decorative applications.

What is H62 brass and how does it compare to other brass alloys?

H62 is a Chinese standard designation for a copper-zinc alloy containing approximately 62% copper and 38% zinc. It is generally equivalent to C27200 (Yellow Brass) in ASTM standards. H62 offers good machinability, moderate strength, and solid corrosion resistance in dry and mildly humid environments — making it a practical choice for precision tubing, fittings, and decorative metalwork.

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

H62 brass has good natural corrosion resistance and will typically hold up well in covered outdoor settings or low-humidity environments. In direct rain exposure or marine conditions, brass will gradually develop a patina (verdigris). For long-term outdoor use, applying a clear lacquer or wax coating is generally recommended to slow oxidation.

What is the tensile strength and load capacity of these tubes?

H62 brass tube typically has a tensile strength of approximately 330–420 MPa, depending on temper and wall thickness. Thicker-walled tubes (1.5mm–4mm) can handle moderate structural loads. For precise load calculations in engineering applications, we recommend consulting a materials engineer, as actual capacity depends on tube diameter, wall thickness, support span, and load type.

Are these tubes compatible with standard pipe fittings or threaded connectors?

These are smooth-bore, unthreaded tubes. They are not pre-threaded and do not come with fittings. They can generally be used as sleeves, spacers, or structural inserts, and can be threaded or soldered by a machinist if needed. For plumbing connections, confirm the OD matches your fitting's bore before ordering.

How do I cut or machine these brass tubes?

H62 brass is generally easy to cut with a pipe cutter, hacksaw, or fine-tooth metal blade. For clean, burr-free cuts, a tubing cutter is recommended for smaller diameters (2mm–15mm). Larger diameters (85mm–100mm) typically require a metal-cutting bandsaw or lathe. Deburr cut edges with a round file or deburring tool before assembly.

Can I solder or braze these tubes?

Yes. H62 brass is generally solderable with standard lead-free or silver solder and compatible flux. It also responds well to brazing. Clean the joint area thoroughly before soldering to ensure a strong bond. Avoid overheating thin-walled tubes (0.5mm) as they can distort.
