Our .012" diameter straightened stainless wire is ideal for using as a forming support for our .018" tubing (N2018). Slide it inside our tubing and it will fully support the tubing wall during the bending process. This is covered in detail in the Forming/annealing link for our tubing.

We have recently redefined the specifications for this wire to greatly improve smoothness and straightness. It is now drawn to size through diamond-coated dies for extra surface smoothness, roundness and diameter tolerance. Straightness is maintained to within 0.010" over the entire length. As a result, this wire is very useful for fabrication of handrails, stair railing, general piping and conduit or anything that requires a 2" diameter scale piping in N-scale. It's also equivalent to 1" in HO-Scale and 2-1/2" in Z-Scale. We supply it in 9-inch lengths, 10 pieces to a package.
