Audited Supplier 1.General Description
Nichrome wire is an alloy made from nickel and chromium. It resists heat and oxidation and serves as a heating element in products such as toasters and hair dryers. Hobbyists use nichrome wire in ceramic sculpture and glassmaking. The wire can also be found in laboratories, construction and specialized electronics.
Nichrome, also known as nickel chrome, is an alloy produced by mixing nickel, chromium and, occasionally, iron. Best known for its heat resistance, as well as its resistance to both corrosion and oxidation, the alloy is incredibly useful for a number of applications. From industrial manufacturing to hobby work, nichrome in the form of wire is present in a range of commercial products, crafts and tools. It also finds applications in specialized settings.
2. Nichrome Properties
Though there are various recipes for nichrome that are dependent on its intended use, the most common form of the alloy is produced from a ratio of 60 percent nickel and 40 percent chromium. Regardless of ratio, all nichrome alloys share properties that make the alloy noteworthy. Nichrome is resistant to heat and corrosion in water, and when heated, it forms a thin layer of chromium oxide that makes it practically immune to oxidation. Most notably, nichrome is highly resistive, causing it to heat up even when exposed to a small electrical current. These traits give nichrome wire a wide variety of uses across industries.
3.Special Applications
Nichrome's characteristics also make it useful in specialty products and projects. Nichrome wire works exceptionally well as a remote igniter and is regularly used in fireworks. It can be used in laboratories to detect the presence of trace metals in flames, and customized electronic cigarettes and other vaporizers often use nichrome wire in their construction.
