Nichrome 80/20 Round Bars, also called NiCr 80/20, are alloy rods composed of approximately 80 % nickel and 20 % chromium, conforming to specifications such as ASTM B344 and UNS designation N06003, also known by Werkstoff number 2.4869. These bars are available in diameters ranging from 4 mm to 500 mm, with finishes including bright polished, black, matt, and rough-turned, and lengths from 1 to 6 meters or custom cut. The alloy’s chemical composition typically includes nickel balance, chromium 20–23 %, and small amounts of silicon and iron, giving it unique resistance properties.

One of the most significant advantages of Nichrome 80/20 Round Bars is their outstanding oxidation resistance at high temperatures, thanks to the protective chromium oxide layer that forms on the surface. This makes them ideal for thermal stability in repeated heating cycles.

Their mechanical strength is also commendable: in annealed form, they may reach a tensile strength of approximately 750 MPa with a yield strength of 275 MPa and elongation up to 42 % Because of the nickel content, they also offer excellent ductility, allowing them to be worked into various shapes without brittle failure. The alloy’s corrosion resistance ensures long service life even under aggressive conditions.

Due to its performance profile, SMM Industries LLP’s Nichrome 80/20 Round Bars find a wide array of applications:

• Manufacture of industrial heating elements for furnaces, kilns, and ovens, where high temperatures and oxidation resistance are critical.

• Use in resistance wire and rods for hair dryers, heat guns, toasters, and other domestic or industrial heating appliances.

• Production of laboratory heating coils and wire for flame sterilization in microbiological labs.

• Construction of electric heater assemblies in extruders for plastic processing, given their stable resistivity and tensile strength under load.

• Components in aerospace and gas turbines, where high-temperature creep strength and dimensional stability are required.

• Application in temperature-control resistors and potentiometers, leveraging the precise resistivity of the NiCr alloy.
