Nichrome (NiCr, nickel-chrome, chrome-nickel, etc.) is any of various alloys of nickel, chromium, and often iron (and possibly other elements). The most common usage is as resistance wire, though they are also used in some dental restorations (fillings) and in a few other applications.

Uses:

When heated to red-hot temperatures, nichrome wire develops an outer layer of chromium oxide,which is thermodynamically stable in air, is mostly impervious to oxygen, and protects the heating element from further oxidation.

Nichrome is used in the explosives and fireworks industry such as electric matches and model rocket igniters.

Industrial and hobby hot-wire foam cutters use nichrome wire.

Nichrome wire is commonly used in ceramic as an internal support. Nichrome wire is used for its ability to withstand the high temperatures that occur when clay work is fired in a kiln.

Nichrome wire can be used as an alternative to platinum wire for flame such as sodium, potassium, copper, calcium, etc.

The alloy price is controlled by the more expensive nickel content. Distributor pricing is typically indexed to market prices for nickel.



When you inquiry, pls specify the details
1. Material and model of wire
2. Diameter, if strip, thickness and width;
3. Quantity;
4. Special requirement if you have.
