Nichrome has a silvery gray coloration. Nichrome wires are quite oxidation resistant. When at a high temperature environment, up to 1200 C (Nicr 8020), both nickle oxide and chromium oxide will be formed. As chromium oxide is more stable than nickel oxide, a layer of chromium oxide will be formed on the surface of the nichrome wire. The diffusion rate D of oxygen through chromium oxide is very low, which is 10-14 cm2/sec.
 
In order to have enough resistance, mental conduct wires always are designed into thin form. They process of oxidation will be quick, making them brittle and break when heated in air. By contrast, not only does nichrome have a excellent oxidation resistant, it also has a good ductility after high temperature use. Besides that, nichrome alloys have a higher emissivity compared to other air-stable resistance alloys. Nichrome alloys will endure a lower element temperature at the same surface load. Moreover, Nichrome alloys will be preferred in low-temperature applications because of its non-magnetic feature. It also has a higher hot and creep strength,  wet corrosion resistance and good wear resistance.

A marked increase in electrical resistivity is observed with increasing chromium additions. An addition level of 20% chromium is considered the optimum for heating elements. 

Application examples:

Nichrome is extensively used in the fireworks and explosives industry.
A popular use of nichrome is in fireworks and explosives as an electrical ignition. When current flows through it, the nichrome glows red hot and heats up extremely quickly even with a small voltage. This makes it an excellent choice for igniting fireworks and other pyrotechnics as it can be activated from a safe distance at the push of a button.

This substance is used in ceramic works. It serves to provide an internal support structure and assist in holding the shapes of clay sculptures while they are soft. Due to its resistance to high temperatures, Nichrome is also used when clay pieces are fired in kilns.
