Flatwire, also known as ribbon wire, has a bright and smooth surface finish and can be manufactured to tight tolerances.
Two manufacturing methods are used by Fort Wayne Metals to manufacture two different types of radius-edged flatwire – drawn and rolled. Flatwire is available in all types of alloys.
- Larger casts
- Cleaner wire
- Less stress induced
- Less camber
- Use of lubrication optional
- Optional isopropyl alcohol use during rolling process (provides lubrication and tighter packaging of spools)
Minimum thickness is 0.0003” (0.0076 mm), and the usual maximum width/thickness ratio is 10:1. It must be kept in mind that these values vary from one alloy to another.
- Better size tolerances
- More consistent and tighter dimensions
It is recommended to stress relieve the drawn flatwire after the initial drawing, as this will help improve its camber and cast. Fort Wayne Metals has the ability to draw this wire down to sizes as thin as 0.0015” (0.0381 mm).
