These enameled resistance wires have been broadly used for standard resistors, automobile parts, winding resist- or etc. using the insulation processing best suited for these applications, taking full advantage of the distin-ctive features of enamel coating.
Furthermore, we will carry out enamel coating insulation of precious metal wire such as silver and platinum wire upon order.
Please make use of this production-on-order.

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 (wire wound resistors, metal film resistors), flat irons, ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular elements and cartridge elements.
