Nichrome Wire

NICHROME WIRE

A common alloy is 80% nickel and 20% chromium, by mass, but there are many others to accommodate various applications. It is silvery-grey in colour, is corrosion-resistant, and has a high melting point of about 1,400 °C (2,550 °F). 

Industrial and hobby hot wire foam cutters use nichrome wire. 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. 

Nichrome wire can be used as an alternative to platinum wire for flame testing by colouring the non-luminous part of a flame to detect cations such as sodium, potassium, copper, calcium etc. For heating, resistance wire must be stable in air when hot. 

Nichrome wire forms a protective layer of chromium oxide.

We sell a range of Nichrome wire, but by no means the full range.

This table shows the part numbers for each size we sell - if a roll in not required you can purchase a length in multiples of 2m (3m for CB933a).

We would be very interested in listing other applications for this wire, if you have one.
