Flatwire

Flatwire, also referred to as ribbon wire, exhibits a smooth, bright surface finish and can be produced to tight tolerances. Fort Wayne Metals utilizes two manufacturing techniques in order to produce two different types of radius edged flatwire: rolled and drawn. Flatwire is available in all alloys.

Rolled
Advantages:
  • Larger casts
  • Less camber
  • Cleaner wire
  • Optional isopropyl alcohol use during rolling process (provides lubrication and tighter packaging of spools)
  • Use of lubrication optional
  • Less stress induced

The typical maximum width/thickness ratio is 10:1; minimum thickness is 0.0003” (.0076 mm). Please note that these values vary from alloy to alloy.

Drawn
Advantages:
  • Improved size tolerances
  • More consistent and tighter dimensions

It is recommended that drawn flatwire be stress relieved after the initial drawing to help better improve its cast and camber. We have the ability to draw this wire down to sizes as thin as 0.0015” (.0381 mm).
