Quick Overview

Resistance wire, Thermocut wire, Pyrography wire, Heater wire

Size: 0.4mm x 10m

Product Description

A heat resisting wire.

Almost any conductive wire can be used for heating, but most metals conduct electricity with great efficiency, requiring them to be formed into very thin and delicate wires in order to create enough resistance to generate heat. When heated in air, most metals then oxidize quickly, become brittle, and break. Nichrome wire, however, when heated to red-hot temperatures, develops an outer layer of chromium oxide,[2] which is thermodynamically stable in air, is mostly impervious to oxygen, and protects the heating element from further oxidation.

Nichrome is used in the explosives and fireworks industry as a bridgewire in electric ignition systems, such as electric matches and model rocket igniters.

Industrial and hobby hot-wire foam cutters use nichrome wire. Similiar application in pyrography wood burning.

Nichrome wire is commonly used in ceramic as an internal support structure to help some elements of clay sculptures hold their shape while they are still soft. Nichrome wire is used for its ability to withstand the high temperatures that occur when clay work is fired in a kiln. Similiar application in glass fusing as costume jewellery.

Ensure the power supply do not exceed the nichrome wire gauge as overheating shortens its life span and break the wire.
