Heat Treatment

Through our subsidiary, Omega Wire Ltd, we hold an extensive range of nichrome (nickel chromium) and cupro nickel feedstocks which are used to manufacture resistance wires and tapes to customers’ specific resistance requirements. Another specialisation is the production of stranded resistance wire for applications where high heat transfer, but a flexible wire, is required.

Primary products of heat treatment industry

Our resistance wire is exported worldwide and is used by furnace constructors, packaging companies, thermal component manufacturers and heat treatment contractors – in fact any thermal environment where quality and reliability are valued.

Case Study 1 – Aircraft windscreen de-icer

Case Study 1 History ImageHistory

An OEM supplier to the military was developing a de-icing system for a prototype aerospace windscreen application. The de-icing system was required to meet a demanding service environment and design criteria were based on tensile strength and electrical resistance.

Our Solution

KPW reviewed the draft specifications and produced samples of resistance strand of varying materials and strand constructions for testing. The final specification was a 7 strand construction of fine nichrome resistance material, annealed and then drawn through a diamond die to meet the exact electrical resistance.

Case Study 2 – Temperature control of food vats

Case Study 2 History ImageHistory

A food producer had suffered a breakdown in the heating system of a food vat. Instead of replacing like for like wraparound elements, they wished to upgrade the heating capability to ensure a more even temperature control.


Our Solution

KPW analysed a sample of the existing wraparound element (which had failed) to determine the exact specification. From the new upgraded heating specification, KPW were able to propose a new heating element, provide samples and subsequently to manufacture the wire ready for the new installation.
