Metals and Alloys | Forms and Applications
FORMS AND APPLICATIONS
Wire, Ribbon and Sheet
Specialty Wire
Targets and Slugs
Most of Sigmund Cohn Corp. metals and alloys are fabricated into wire form, in many cases to as small as .0003" diameter. Frequently round wire is rolled to rectangular cross sections as thin as .0002" with a width-to-thickness ratio of 2:1 to as much as 75:1. Some wire is electroplated with Gold for improved corrosion resistance or with Tin or Lead for improved solderability. In many cases, an insulation is required. An appropriate enamel is applied onto round wire to rigid specifications including enamel thickness, uniformity and temperature rating. Multistrand wire is available, either stranded or braided.
