Resistance Alloy

Introduction

Resistance alloys have high resistivity and used in many varied applications—from small household appliances to large industrial process heating systems and furnaces. In appliances or industrial process heating, the heating elements are usually either open helical coils of resistance wire mounted with ceramic bushings in a suitable metal frame, or enclosed metal-sheathed elements consisting of a smaller-diameter helical coil of resistance wire electrically insulated from the metal sheath by compacted refractory insulation.

NiWire has been manufacturing resistance alloys and heating alloys from its foundation. Our stength is making wires, strips, ribbon and foil, including NiCr alloys and Fe-Cr-Al alloys.

We can also make stranded nichrome wire in a range of sizes. Our resistance wires are stranded into 7, 19, 37 or other type. Construction can be based on “king” wire specified diameter with outer wires of a different diameter.

In addition to their use as heating elements in furnaces and appliances, nichrome alloys are also used in instruments and control equipment to measure and regulate electrical characteristics, for example, resistors. Such as braking resistors for railway and traffic applications with spot-welded strip elements made from NiCr 8020.

Normally thickness: 0.6mm-1.2mm, width: 60mm-150mm, other sizes available per request

Strips produced by NiWire has a uniform resistance, having been supplied to many manufacturers of breaking resistors, neutral grounding resistors, and so on.

high resistivity, good oxidation resistance and very good form stability. It has good ductility after use and excellent weldability

high resistivity, good oxidation resistance and very good form stability

excellent material for resistance wire and strip

good ductility after long time usage, good mechanical property at high temperature and good weldability
