Nichrome wire and iron PTCRs are called electric wire, because they all belong to the electric resistance alloy, used as a heating element or the heating element, they are also known as the resistance wire, because they are often used as a resistance element.
Nichrome wire has high surface electrical resistivity, good oxidation resistance, high temperature level, high strength in high temperature, good processing properties and weldability, which can be widely used in metallurgy, household appliances, machinery manufacturing as heating elements and electrical industry as resistance materials. It has long service life, but because it contains nickel, so the price is relatively high.
The characteristics of nickel chromium wire:
①High strength at high temperature
②Long term use and then cool down, the material will not become brittle
③The radiation rate of Ni Cr alloy with full oxidation is high than that of Fe Cr Aluminum Alloy
④Nonmagnetic
⑤Besides the sulfur atmosphere, it has good corrosion resistance
