Nichrome is a special nickel and chromium alloy. Cr20Ni80 belongs to a kind of electro thermal alloy, which has stable structure and electrical physical performance, in addition, good high temperature mechanical property, fine could plastic deformation and weld ability, as a result of which. it cannot have the brittle fracture due to long-term use. The alloy is widely used in manufacturing the household appliances and heating elements below the working temperature of 1000'C. Technical Specification: Gauge: 24 SWG , Resistance: 4.39ohm/meter

Nickel-chromium steel, also known as Nichrome wire, is a type of resistance wire that is commonly used in heating elements and resistors due to its high resistance to heat and corrosion. The alloy is typically composed of nickel and chromium, but may also contain other elements such as iron and silicon.

The specific product you've mentioned is a Nichrome wire in silver color, measuring 1 meter in length and with a thickness of 0.56 mm or 24 gauge. It's being sold by Add Link It Solution which is a company that provides various electronics components for DIY projects.

This wire is commonly used in a wide range of applications such as in electric heaters, toasters, hair dryers, and other similar devices. It is also used in the production of electronic cigarettes and vape pens. It is known for its high resistance to heat and corrosion, making it a durable and long-lasting option for heating elements.
