Nichrome
Technical characteristics
In addition to nickel, nichrome contains such elements as iron, aluminum, silicon, manganese, titanium, sulfur, phosphorus and carbon. The main advantages of this multicomponent material are:
-mechanical strength;
-high operating temperature.
Relevance
Such nickel-based alloys are used in the production of heating elements in devices of various types and purposes. That is, products made of nichrome can be found both in an industrial electric furnace and in a soldering iron. The physical properties of different alloy grades are determined by the proportion of the main components. Nickel tends to dissolve other metals without losing corrosion resistance, heat resistance, ductility. Chromium increases corrosion resistance, heat resistance and hardness of the alloy.

Advantages of Nichrome
One of the most important qualities of this alloy is its rare electrical resistance equal to 1.12 Ohmm2/m and its high melting point. X20H80 is capable of withstanding heat up to 1200ºC, while X15H60 up to 1125ºC. At the same time, the minimal temperature coefficient of expansion prevents the wire from sagging. Such advantages together with resistance to corrosion make nichrome an indispensable element for heating in an aggressive environment at high temperatures. A fairly large range of products is made from it because it is malleable, easy to drill, stamp, weld, and can be rolled into very thin wire. Nichrome is a rather expensive alloy, but its high cost is offset by its strength, durability, reliability - a full measure.
