K & S Precision Metals 9209 Round Brass Tube .029 x 1/4 x 36-In hardware

Brass tube dimensions

The K & S Precision Metals 9209 is a round brass tube measuring .029 wall thickness by one-quarter inch outside diameter and thirty-six inches long. It suits modellers, hobbyists and light fabricators who need a true brass alloy for machining, soldering or decorative work. The material cuts cleanly with hand tools and accepts a polished finish without plating.

Behaviour under load

Brass work-hardens when bent repeatedly so the tube holds its shape under steady pressure but will fatigue if cycled past its yield point. The thin wall keeps weight low while the alloy resists corrosion in indoor and sheltered outdoor use. Annealing restores ductility if tighter radii are required later.

Upgrade path

This tube replaces solid brass rod when weight saving matters and upgrades from aluminium or plastic tubing where electrical conductivity, solderability or a genuine brass appearance are required. The jump is worth it when the project demands a metal that machines like brass but weighs significantly less than a solid bar.
