The inner diameter equals the outer diameter minus twice the wall thickness. For example, a 6 mm OD tube with a 0.5 mm wall has an ID of 6 − (2 × 0.5) = 5 mm. Use this formula to confirm clearance for any rod, wire, or fitting you plan to insert.

For decorative or lightweight applications such as model framing or inlay work, thinner walls (0.15–0.3 mm) keep weight low and are easy to cut. For structural or load-bearing uses — standoffs, pneumatic lines, or mechanical linkages — choose a wall thickness of 0.5 mm or greater relative to the OD to maintain rigidity and resist deformation.

H62 brass resists oxidation well in dry and mildly humid indoor environments and will develop a natural patina over time. For prolonged outdoor or marine exposure, consider applying a clear lacquer or wax coating, as brass can tarnish and is susceptible to dezincification in aggressive salt-spray conditions.

Yes — this is a common technique in scale modeling and telescoping assemblies. Select an inner tube whose OD is equal to or slightly smaller than the ID of the outer tube. Because wall thicknesses vary, check the calculated ID of the outer tube against the OD of the inner tube before ordering to ensure a slip fit or press fit as needed.

A rotary pipe cutter (tube cutter) gives the cleanest, square cut with minimal burring for tubes 2 mm OD and above. For very small diameters (under 2 mm), a fine-tooth jeweler's saw or a sharp hobby knife scored around the circumference works well. A lathe parting tool is ideal if you need multiple precise lengths. Deburr the cut end with a round file or deburring tool before assembly.

Yes. H62 brass solders readily with standard 60/40 or lead-free soft solder and flux. For stronger joints, silver brazing rod with a propane or MAPP torch works well. Clean the surface with fine abrasive or flux before heating to ensure good wetting. Avoid overheating thin-wall tubes, as excessive heat can distort the tube geometry.

The 200 mm (~7.87 in) length suits shorter components, prototypes, or situations where you need to minimize waste. The 500 mm (~19.69 in) length is more economical per millimeter and is preferred when you need to cut multiple pieces from a single stick or when the finished part itself is long. Both lengths share the same OD and wall thickness specifications.
