Ni80Cr20 Electric Alloy NiCr8020 Resistance Heating Nickel-chromium alloy
Nickel-chromium alloy, nickel chromium iron alloy with high resistivity, surface oxidation resistance is good, and have higher strength at high temperature, good processability and weldability, which can be widely used in metallurgy, electrical appliances, machinery manufacturing, etc do resistance material heating elements and electrical industry.
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.
