Product Description

Stranded nichrome heating wire for Ceramic heating pad

Stranded nichrome heating wire is mainly used for making heater pad with ceramic,and heating element repair kit etc.

Generally,the conductor will be Ni80Cr20,Ni60Cr15,and the wire comes from 7,19,37 multi-strands:
7=1+6
19=1+6+12
37=1+6+12+18

The conductor can be also other nichrome,FeCrAl,CuNi alloy,and the size can be custom produced.

Our Standard material,DIN 250 consist of 500meters per spool:

Alloy	Nominal total diam.(mm)	Strand Construction (mm)		Resistance (Ohms/M)
