Some of the Subtleties of Non-Standard Conductors

Custom-shaped conductors have been around for many years and are used in a wide range of applications, from everyday consumer goods like toasters to high-end medical devices and cutting-edge electronic products. The question is: do you really understand custom-shaped conductors as well as you think you do? Will your company’s future products also incorporate such components? Even if the answer is “perhaps,” here are some frequently asked questions about custom-shaped conductors and their applications.

Question: What do we mean by “non-standard” conductors?
Answer: Plain wire is circular in cross-section and is produced by rolling metal bar stock through rolls. Shaped wire, on the other hand, is wire that has been further processed, typically by cold-drawing through drawing dies to alter its shape and dimensions. Common shapes of shaped wire include rounded-square, right-angled square, elliptical, hexagonal, octagonal, strip-shaped, and triangular.

Question: With regard to non-standard shapes, what size range of metal wire qualifies as “fine” wire?
Answer: Today, the diameter of irregularly shaped fine gold wire can be as small as 0.008 millimeters—less than one-tenth the diameter of an average human hair. On the other hand, gold wire with a diameter of 0.0508 millimeters can be further rolled into precision gold ribbon that is only 0.00635 millimeters thick and 0.127 millimeters wide. Question: Irregular

Question: What are the common applications of shaped conductors?
Answer: Their applications are extremely broad, encompassing guitar amplifier pickups, metallic “keys” in aerospace vehicles, metal conduits, Muni springs, connector pins, integrated circuits, microwave systems, power coils, audio speaker coils, microwave coaxial cables, and miniature railway tracks. In some applications—such as the heating elements in toasters—flat metal strips are used to provide a larger heat-dissipating surface area.
In addition to these common applications, there are numerous highly specialized uses, such as cochlear implants, cardiac catheters, and telemetry devices. Special-shaped wire is also employed in certain niche applications, for example, the coils of linear motor actuators in computer disk drives. For instance, a customer of Dehong Conductor Technology requested that its wire be square-shaped and insulated with a proprietary Pyre-ML enameled wire.

Question: What level of quality should non-standard conductors achieve?
Answer: Fine-wire manufacturers are capable of producing “Six Sigma” products with consistently high quality, meaning that 99.99% of the output can meet specifications. Although wire-drawing technology has not yet reached perfection, achieving the precise tolerances and specifications required for modern applications should pose no problem.

Question: Does custom-shaped conductor fabrication require technical support?
Answer: If a customer lacks the necessary in-house technical support, they should be able to rely on their supplier. For example, a wire manufacturer should have engineers or other technical personnel who can provide design assistance. This is especially important in the early stages of the development process, as it allows many potential pitfalls— including unnecessary costs—to be avoided. In fact, we frequently receive calls from product design engineers seeking advice or ideas on material selection, dimensioning issues, and manufacturing processes.

Question: How long does it take to produce custom-shaped fine metal wire?
Answer: Orders can be completed in as little as seven days. In some cases, manufacturers may produce more than the customer’s order quantity and stock the excess inventory to enable faster fulfillment of future orders. Nevertheless, it is still best to confirm in advance whether the custom-shaped wire processor can deliver on time and respond promptly to orders.
