Fort Wayne Metals HHS Tube (Helical Hollow Strand) furthers our excellence in stranding and cabling of medical grade wire.
Helical Hollow Strands are designed using solid modeling according to mathematical formulas. Using parametric design, many design considerations can be evaluated in a short time. Materials are normally spring temper. Nitinol HHS is
provided in the superelastic condition. Flexibility can be influenced by design variables including ID, OD, Wire Size, Filar Count and other processing.
Inside Diameter: 0.001" (0.0254mm) to 0.130" (3.302mm) Outside Diameter: 0.0025" (0.0635mm) to 0.160" (4.064mm) Filars 6 to 18 Layers 1 to 3 (more may be available) Lengths from 1" to 10' (longer possible depending on design) Pitch Left, Right, Unidirectional, Reverse
Customer specified performance testing:
Droop, Compression, Yield (elongation at load) or Torque
HHS Tube is a stranded wire with an open center working channel which can be constructed of numerous material types all drawn on site. HHS Tube designs are tailored to customer specifications of dimension, tension, compression, torque, and pitch direction while exhibiting high kink resistance and excellent whip free characteristics. Single, dual and triple layer HHS Tube can be manufactured for varying flexibility and control with differing filar counts and sizes per layer.
