Nichrome Bare Wire 30 Swg

Nichrome Bare Wire 30 Swg

Product Code : JA-EE-7630

Nichrome Bare Wire 30 Swg (SKU JA-EE-7630) is a fine, bare 30 SWG high temperature resistance wire of nickel-chromium-iron alloy that glows red when a current heats it. Being finer than the 28 SWG size, it reaches a red glow at a lower current, which suits small heating elements, compact rheostat windings and classroom glowing-wire demonstrations. JaincoLab supplies this 30 SWG nichrome wire to school and college physics laboratories and workshops.

Specifications

Nichrome Bare Wire 30 Swg is described as a high temperature resistance wire that glows red, made of a nickel-chromium-iron alloy especially suitable for heating elements, rheostats and similar high temperature applications; diameter and reel weight are confirmed on the quotation.

Glowing-wire and heater uses of 30 SWG nichrome

Because it is fine, 30 SWG nichrome wire glows red at a modest current, so teachers use a short length on a low-voltage supply to show electrical energy turning into heat and light, and technicians wind it into small heating elements and compact rheostats for teaching apparatus.

  • Low-current glowing-wire demonstrations
  • Small heating elements for teaching apparatus
  • Compact rheostat and variable resistor windings
  • Model of a filament or heater in lessons on the heating effect of current

Frequently asked questions

What alloy is this nichrome wire?
The listing describes it as a nickel-chromium-iron alloy for high temperature use.

Why choose 30 SWG for demonstrations?
A fine wire has more resistance per metre, so it glows red at a lower current than heavier gauges.

What applications is it suited to?
Heating elements, rheostats and other high temperature applications.
