nichrome resistance wire,
AWG24 26 28 30 32 34 Nichrome 80 Wire Nichrome Heater Wire
Nichrome, a non magnetic alloy of nickel and chromium, is commonly used to make resistance wire.
Because it has a high resistivity and resistance to oxidation at high temperatures. When used as a heating element, resistance wire is usually wound into coils.
Nichrome wire is commonly used in ceramics as an internal support structure to help some elements of clay sculptures hold their shape while they are still soft. Nichrome wire is used because of its ability to withstand the high temperatures that occur when a clay work is fired in a kiln.
Features of manganic resistance heating wire:
Electric wire is with the high quality alchrome and
nicklechrome alloy which produced by our own company, adopts computer control furnace silk power, winding shaping by the highspeed automatic winding machine. The feature of the product is have withstanding high temperatures, fast temperature rise, long service life, stable resistivity, small power deviation, uniform screw pitch after drawing, and clean surface, widely used in small electric furnace, muffle furnace, heating air-conditioning equipment, all kinds of oven, electrical heated tube, and home appliances ect. Can design and produce all kinds non-standard electric stove strip by customer’s request.
