Nichrome wire 2m (0.4 or 0.5mm)



Nichrome Wires are used widely in many industrial products and have some fascinating applications for hobbyists.

The material, Nichrome, is a mix of Chromium and Nickel and offers high-temperature resistance. Also, as it has a chromium oxide layer on its surface, it does not corrode like iron, so is stable when used at high temperatures.

If a DC current is passed through a thin nichrome wire, it heats up and the heat can be used for many applications. Typical industrial uses for nichrome wires are in iron boxes, toasters, hairdryers, electrical cigarette lighters, and even electric room heaters.

The coil of Nichrome wire offered can be used by hobbyists for many similar applications.

Different Diameters: 

Hobbyist offers these Nichrome Wires in various diameters.

Different diameters mean that using the same current, you can create different heating effects. Thinner wires, as they have higher resistance, tend to get hotter and hence get to higher temperatures quickly.

Diameters offered are 0.10mm, 0.12mm, 0.15mm, 0.20mm, 0.25mm, 0.30mm, 0.32mm, 0.35mm, 0.40mm and 0.50mm.

Resistance data (per meter) is provided below.

Hobbyist Applications: 

These wires can be used to design cutting machines. The hot wire is used as a knife that melts and cuts through the foam to make various shapes and products.

Another project is where the same approach is used to heat and soften plastic materials such as acrylic, plexiglass, and polycarbonate to bend sheets to make shapes.

RC planes: Yet another example of the use of Nichrome wire is the making of Airfoils by model plane enthusiasts. The foam material is cut in the shape of airfoils to make the wings of model airplanes.

Other potential projects include

  • Making your own toaster to get shapes on the toasted bread
  • Making your own lighter
  • Making your own hairdryer
  • Miniature iron box
  • Making your own soldering machine, etc.

Typically all projects using Nichrome Wire would need a power source - for DC power. Hobbyist also sells DC Power Source units.
