Code: Cr20Ni80,Cr15Ni60,Cr20Ni30 Material: Ni-Cr-Fe alloy strip Specifications: Thickness:0.5-3.5mm,width:5.0-45.0mm Features: Our company produces nickel-chromium, nickel, ferrochrome strip with high purity, resistivity stability, good oxidation resistance, surface and higher in the high temperature strength, good processing properties and weldability, can be Widely in metallurgy, household appliances, machinery manufacturing and electrical heating elements made to do resistance materials industry.
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.
