Nichrome Wire

Nichrome Wire

Nichrome wire is made of a non-magnetic alloy composed primarily of nickel, chromium, and iron. Nichrome is characterized by its high resistivity and good oxidation resistance. Nichrome wire also has good ductility after use and excellent weldability.

The number that comes after the Nichrome wire type indicates the percentage of nickel in the alloy. For example, "Nichrome 60" has approximately 60% Nickel in its composition.

Applications for Nichrome wire include heating elements of hair dryers, heat sealers, and ceramic support in kilns.

Types of Nichrome Wire

Nichrome 20

This alloy has moderate resistance to oxidation.

Applications: Refractory anchor bolts, element fastener, and terminals attached to nickel-chromium heating elements.

Nichrome 30

This alloy is also used for heating cables and rope heaters in defrosting and de-icing elements, resistors, floor heaters, electric blankets and pads, baseboard heaters, and car seats.

Applications: Heavy duty rheostats, open coil heaters in HVAC systems, night-storage heaters, solid hot plates, convection heaters, and fan heaters.

Nichrome 40

Applications: Night-storage heaters, convection heaters, heavy duty rheostats, fan heaters, heating cables and rope heaters in defrosting and de-icing elements, electric blankets and pads, car seats, baseboard heaters and floor heaters, and resistors.

Nichrome 60

Nichrome 60 is is ideal for use as heating elements in household utilities and in moderate heat, high humidity environments.

Applications: Metal sheathed tubular elements used in, for example, hot plates, grills, toaster ovens and storage heaters. The alloy is also used for suspended coils in air heaters in clothes dryers, fan heaters, hand dryers.

Nichrome 70

Nichrome 70 is great for reducing atmospheres, as it is not subject to 'green rot'.

Applications: This type of Nichrome wire is used in electrical heating elements in industrial furnaces.

Nichrome 80

Nichrome 80 has very good form stability. This alloy offers superior service life compared to other Nichrome wire types due to the excellent adhesion properties of its surface oxide.

It is commonly used for industrial furnaces and heating elements in home appliances.

Applications: Water heaters, flat irons, ironing machines, plastic moulding dies, soldering irons, metal sheathed tubular elements and cartridge elements.

Nichrome 60

Nichrome 60 wire is generally used to manufacture electrical resistance for insulated and open appliances. It is widely used in the application of industrial furnaces and even provides the means to melt metals. At high temperatures, Nichrome 60 wire will resist embrittlement, meaning that it will last you longer than less resolute variations. It has good plasticity when cold, making it easy to weld, manipulate and shape to serve your specific needs.

Nichrome 60 is less resistant to rust and oxidation as Kanthal, but it has a higher high wet corrosion resistance and is made of a non-magnetic alloy. This means that in acidic environments or areas where a wire is likely to come in contact with a liquid or electrolyte medium, Nichrome 60 wire will resist degradation at a higher level and continue to function for a longer period of time.
