1/8" Square Brass Tube
Upgrade your model-making projects with our premium 1/8" (3.2mm) Square Brass Tubing from Albion Alloys, supplied in 12" (305mm) lengths. Part of our high-precision metals range, this brass tubing is engineered for exceptional accuracy, strength, and consistency, perfect for scale modelling, engineering prototypes, miniature mechanisms, and custom fabrication.
Unlike K&S Metals (manufactured in the USA), Albion Alloys brass tubing is proudly made in the UK to extremely tight tolerances. Each square tube is designed to telescope smoothly into the next size up, ensuring perfect alignment for scratch-built structures, sliding mechanisms, and precision assemblies.
The high-quality polished finish ensures outstanding workability, making the tubing easy to cut, solder, glue, drill, and paint while maintaining clean, professional results.
External dimensions are listed as standard, and the table below also includes internal measurements to help you select the ideal size for your model or project.
