Build clean, rigid structures with the MODULAR Round Aluminium Tube — 6.0 mm OD x 0.50 mm wall, 1000 mm length. Made from Al Mg Si 0.5 (a hardenable, construction-grade alloy), this thin-walled tube delivers high strength-to-weight performance with a smooth, machinable surface—perfect for architectural model making, signage spacers/standoffs, display fixtures, décor and DIY mechanisms.

Why makers choose it

• Precise dimensions: 6 mm outer diameter, 0.5 mm wall for lightweight yet sturdy frames

• Versatile alloy: Al Mg Si 0.5—widely used in construction and display applications

• Easy to work: Cut with a circular saw, hacksaw/metal frame saw, or fine tooth hand saw

• Formable: Can be bent cleanly—fill tightly with sand and cap ends to prevent buckling

• Bonding options: Not suitable for soldering; bond with two-part epoxy or cyanoacrylate (CA). For modelmaking, Ruderer plastic glue or UHU Hard can also be used (check compatibility with adjoining materials)

Typical applications

• Architectural model columns, trusses, masts, railings

• Pre-cut distance pieces for mounting signs and panels

• Furniture accents, display frames, craft and robotics projects

Specifications

• Profile: Round aluminium tube

• Outer diameter (OD): 6 mm

• Wall thickness: 0.5 mm

• Length: 1000 mm (1 m)

• Alloy: Al Mg Si 0.5

• Finish: Mill (ready for sanding, priming, painting or clear-coating)

Working notes

• Deburr edges after cutting for a clean fit

• Dry-fit before gluing; degrease surfaces for best adhesion

• For bends, use a former/mandrel where possible and the sand-fill method to avoid kinks.
