INTRODUCTION OF PRODUCT
A Resistance Alloy used in electrical heating application. It is recommended for use in dry air applications up to 2150 degrees F with good hot strength. It is an alloy of nickel and chromium with high electrical resistance; used for resistance heating elements. Nichrome 80/20 is an ideal material, because it has relatively high resistance and forms an adherent layer of chromium oxide when it is heated for the first time. Material beneath the wire will not oxidize, preventing the wire from breaking or burning out.
Applications:
These elements are commonly found in precision heating applications such as Medical Diagnostics, Satellite, and Aerospace Electrical appliance industry, Ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular elements,cartridge elements
Wire packing in spools
Carton packing with plastic film, plywood box suitable for sea & air delivery
Woven belt packing with plastic film, plywood box or pallet suitable for sea & air delivery
