Question

Nichrome is an alloy made of

Answer 1

Hint: Nichrome is the oldest air-stable resistance-heating alloy. Nichrome alloys consist of nickel, chromium, iron, and sometimes other elements. Nichrome is widely used in heating elements. It is wound in wire coils to a certain electrical resistance, and current passed through to produce heat.

Complete answer:
Nichrome is a non-magnetic alloy of nickel and chromium.
Properties of nichrome wires
Nichrome alloys are known for their high mechanical strength, as well as their high creep strength. Learn some of the benefits of using this material below.
Nichrome is known for remaining ductile, even after long usage.
Compared to other air-stable resistance alloys, Nichrome alloys have a higher hot and creep strength.
When fully oxidized, Nichrome alloys have a higher emissivity compared to other air-stable resistance alloys. This means that at the same surface load, the element temperature of Nichrome is lower than other alloys.
In some low-temperature applications, a non-magnetic material is preferred. Nichrome is non-magnetic, making it the preferred choice over other air-stable resistance alloys, which are only non-magnetic above $$600{}^{\circ }C$$.
While there are some exceptions (such as atmospheres containing sulphur and certain controlled atmospheres), Nichrome alloys typically have a better corrosion resistance at room temperature compared to non-oxidized air-stable resistance alloys.
$$\therefore$$ Nichrome is an alloy made of nickel and chromium.

Note:
Some other common applications for Nichrome alloys include: ironing machines, water heaters, soldering irons, metal sheathed tubular elements, cartridge elements, quartz tube heaters, infrared emitters and other precision heating element (heater) applications.
