Omega Resistance Wire is a well established and highly qualified manufacturer of electrical resistance wires and nickel alloy wires for applications demanding high quality, reliability and service. Our products are produced to the highest international standards, and we export worldwide to some of the world's most distinguished companies.
We continually strive to provide service of the highest caliber. The skill, experience and friendliness of our staff enable us to deliver this service and to provide the solutions to your problems. This service dedication and commitment to quality, together with our extensive stocks of wire and tape and our wide processing capability ensure that we can reliably meet your requirements.
Manufactured from wire, tape, ribbon or strip, most frequently from Nichrome 80/20 material due to its high resistance. Elements are either embedded or supported on the surface of the electrical insulating material. Applications include ovens and heat treatment equipment, furnaces for industrial heating, floor heating.
Used for the accurate cutting of complex shapes from polystyrene foam (EPS) - by hand or by CNC machine - and used extensively in the packaging industry. Also used for architectural mouldings, theatrical props and modelling.
Heat Sealers are used to seal thermoplastic materials using heat generated from resistance wires, ribbons or strips. Sealers are either Impulse (for sealing similar materials) or Constant (sealing dissimilar materials). Typical applications are packaging and bag sealing.
Resistors are common components of electrical networks and electronic circuits, and are present in most electronic equipment. Resistors are made from various compounds as well as high-resistivity alloy such as nichrome wire.
Special nickel alloys have many industrial uses other than electrical resistance heating. Such examples are corrosion and heat resistant applications of the Monel and Inconel alloys in industries such as chemical and food processing.
Omega manufactures a range of stranded resistance wires which are used extensively in the on-site heat treatment of pressure vessels and pipework. Popular sizes are held in stock for immediate delivery worldwide.

Nickel Chrome alloys, or Nichrome alloys have excellent electrical resistance properties, operating at temperatures up to 1200 °C. This property coupled with high resistance to oxidation and chemical corrosion makes these alloys ideal for use as resistance wires in furnaces and heat treatment applications.
Copper Nickel alloys or Cupro Nickel alloys operate at temperatures up to 400°C, have a low temperature coefficient of resistance and medium resistivity, plus high resistance to oxidation and chemical corrosion. Typical applications are electrical resistors and thermocouples.
ICA Alloys or Iron Chrome Aluminium alloys are ferromagnetic alloys that can be used as resistance wire, particularly in electrical heating elements. These alloys can operate at high temperatures up to 1250°C, but suffer from higher corrosion than nickel chrome alloys.
Nickel Iron Alloys or Glass Sealing Alloys have a low and constant thermal expansion. As the coefficient of thermal expansion approximately matches that of glass, the alloy is used extensively as a glass seal in the manufacture of lamps and electronic equipment.
Nickel Alloys - the most common of which are Nickel (Alloy 200), Monel (Alloy 400) and Inconel (Alloy 600) - exhibit very high strength and corrosion resistance at elevated temperatures, plus excellent electrical resistance.
Omega Resistance Wire's range of wire drawing machines enables wire to be drawn in diameters from 0.10mm up to 10.00mm. Wire is drawn in a variety of materials including the nickel chrome alloys, nickel copper alloys and stainless steels. A high quality, diamond drawn finish is standard.
Our annealing facilities comprise 2 strand annealing lines.
Omega Resistance Wire has substantial capability in producing resistance tape or ribbon, rolled flat wire and precision sheared strip. Products are generally manufactured to a specified resistance but can be produced to tight dimensional tolerances.
We operate a range of tubular stranding equipment capable of producing stranded wire ropes in nickel chrome alloys, nickel copper alloys, nickel and stainless steel. Strand can be manufactured to resistance and set spool lengths, or cut lengths as required.
Omega Resistance Wire has a comprehensive range of straighten and cut to length machines. Our capability extends from very fine wires to large diameter, and flat wires, stranded wires and strip products. A particular expertise is the straightening and cutting to length of very fine wires to strict dimensional tolerances and surface finish.
Wire can be supplied in coils of specified dimensions and weights. Additionally, we can supply the wire on spools (high strength thermoplastic bobbins) that are available in a range of standard sizes and weights.
