Electric Heating Nichrome Alloy Bright Spring Wire Diameter 4mm 3mm
In Muffle Furnace Ohmalloy Material Co., Ltd is one of the leading non-ferrous metal processing enterprises in
China, with more than 10 years of experience. In addition to
products from brass, bronze, copper-nickel, nickel, as well as
copper-zinc alloys, the company manufactures nichrome wire, strips,
tapes, rods and nets from alloys X15H60 and X20H80.
Nichrome is a nickel-chromium alloy with very high heat resistance
and electrical resistance - its working temperature is 800 - 1100
degrees Celsius, and the melting temperature is about 1400 degrees
Celsius.
All these properties allow the use of wires and strips of nichrome
for the manufacture of heating elements in laboratory and
industrial electric furnaces, various electric heat-generating
devices, for example, in heat guns and industrial hair dryers, as
well as water heating systems.
Basically, on the Russian market there are two brands of nichrome -
X15H60 and X20H80. The difference between them lies in the
operating and melting temperatures, as well as in strength and
ductility, in all these indicators the X20H80 alloy is the leader.
• Nichrome X15H60 - Contains 55-61% Nickel and 15-18% chromium. The remaining
components are iron and other impurities.
• Nichrome X20H80 - Contains 74% Nickel and 23% chromium; iron, silicon and
manganese are also present.
Ohmalloy also produces nichrome wire, tapes, rods and nets from
alloy X20H80-N, whose composition includes microalloying zirconium. Compared with
X20H80, products from this alloy are characterized by high surface
quality and contain less impurities, which ultimately leads to a
longer product life.
OhmAlloy109
(Common Name:Ni80Cr20, Nikrothal8 ,MWS-650, NiCrA, Tophet A,
HAI-NiCr 80, Chromel A, Alloy A, Alloy 650, N8, Resistohm 80,
Stablohm 650, Nichorme V, Nikrothal 80.)
OhmAlloy109 is a nickel-chromium alloy (NiCr alloy) characterized
by high resistivity, good oxidation resistance and very good form
stability. It is suitable for use at temperatures up to 1200°C,and
hold a superior service life compared to Iron chromium alumium
alloys.
Typical applications for OhmAlloy109 are electric heating elements
in home appliances, industrial furnaces and resistors( wirewound
resistors, metal film resistors), flat irons, ironing machines,
water heaters, plastic moulding dies, soldering irons, metal
sheathed tubular elements and cartridge elements. Normal composition%| C | P | S | Mn | Si | Cr | Ni | Al | Fe | Other | | Max | | 0.03 | 0.02 | 0.015 | 0.60 | 0.75~1.60 | 20.0~23.0 | Bal. | Max 0.50 | Max 1.0 | - |
