OhmAlloy109
(Common Name: Ni80Cr20,Nikrothal 8,MWS-650,NiCrA,Tophet A,HAI-NiCr 80,Chromel A,Alloy A,Alloy 650,N8,Resistohm 80, Stablohm 650,Nichorme V,Nikrothal 80.)
A marked increase in electrical resistivity is observed with increasing chromium additions. An addition level of 20% chromium is considered the optimum for electrical resistance wires suitable for heating elements. This composition combines good electrical properties with good strength and ductility, making it suitable for wire drawing.
Application Examples
Nichrome is used to prepare bridgewire for electric ignition systems like model rocket igniters, electric matches and electronic cigarettes.
Nichrome wires are used to test the flame color in the non-illuminated parts of cation fire from the cations of sodium, copper, potassium and calcium.
Nichrome is also used in microbiological laboratories.
This substance is used in the manufacturing of motorcycle silencers.
