A thin-walled brass tube with an outer diameter of 0.9 mm and a bore of 0.7 mm. It can be soldered, bent, and slid into the neighboring sizes of the same range.
Responsibility details are not available.
A drawn brass tube measuring 0.9 millimeters across the outside, with a 0.7 millimeter bore inside. The wall thus works out to a tenth of a millimeter, yet the profile still holds a round shape even when bent over your fingers or around a cylindrical form.
The greatest practical advantage is that the whole size range steps up in tenths of a millimeter. The inside of one piece matches the outside of the one a size smaller, so parts can be slid into each other to build telescoping assemblies: extending landing-gear legs, two-stage shock absorbers, extending antennas, or axles that are meant to actually rotate on the finished model.
Modelers shape it into gun muzzles, handles and footpegs, tube frames, motorcycle exhausts, engine-bay plumbing, and supports for small structures. Compared with a plastic profile it withstands far more stress and holds up where styrene would crack. Brass also takes solder, so joints can be soldered for a result stronger than any glued bond.
Do not use wire cutters to shorten it — they will squeeze the end into an oval. Rolling it under a knife blade on a hard surface, or a small tube cutter, works well instead. Remove the burr with a needle file and clear the bore with a 0.7 mm drill bit. Before painting, degrease the surface with alcohol and apply a primer made for metal, since plain acrylic paint would have nothing to grip on bare brass. The end can be flattened with pliers if you need an eye for a pushrod or a flat fitting from the tube.
