19*0.55mm Stable Resistance Nickel Alloy Ni80 Stranded Wire/ Stranded Cable
Nichrome electric heating alloys with high and stable resistance, corrosion resistance, surface oxidation resistance is good, a better under high temperature and seismic strength, good ductility, good workability and weldability.
It is widely used in industrial electric furnace, metallurgy, household appliances, machinery manufacturing, heating element and resistor varistor other material.
The commercial levels consist of Nichrome and Brightray. The little upgradation for this composition can be made to improve the wire for certain operations. With the inclusion of suitable reactive alloy metals an alteration in the properties is certain. The performance conditions of nichrome alloy wire are extremely influenced by its composition.
However the concentration alternations have minor impact on mechanical features, large concentration of reactive metals causes to avoid the flaking of scale while periodic heating and cooling.
The nichrome wire with binary expression of 90/10 is used for heating operations and it has highest performance temperature of 1100 degree Celsius. Moreover nichrome heating wire is also used in thermocouples.The combination of nickel and chromium in 90:10 ratio is more preferred for thermocoupling as compare to 95:5 nickel chromium addition.
