Widely used as more precisely controlled stranded wire within the cable industry; optimum properties for high performance at elevated temperatures

Nichrome Stranded Resistance Heating Wire

We have developed a range of stranded resistance wires in the FeCrAl alloys, Nichrome alloys and other Nickel alloys. They are widely used as more precisely controlled stranded wire within the cable industry. These alloys possess the optimum properties for high performance at elevated temperatures and in other adverse conditions where reliability and quality is of paramount consideration.
Stranded Resistance Heating Wire Properties:

Alloy	Nominal Composition, %					Resistivity at 20°C		Max. temp°C
	Ni	Cr	Fe	Al	Oth
Nichrome Ni80Cr20	80	20					1.09Ωmm2/m		1250
Nichrome Ni60Cr15	60	16	Bal				1.11Ωmm2/m		1150
FeCrAl S1		6	Bal	25			1.45Ωmm2/m		1450
FeCrAl 0Cr25Al5		5	Bal	25			1.42Ωmm2/m		1250

Stranded Resistance Heating Wire diameters:

Nominal diameter to be determined from single-end wire diameters, which have to meet resistance requirements. Resistance generally takes priority over diameter.

The calculation is:

Strand normal diameter = single-end diameter x F

F=3 for 7-strand

F=5 for 19-strand true concentric

F=7 for 37-strand true concentric

Size range

Up to 37 wires (ends) of diameter between 0.20-0.85 mm.
