Engineered for Electronics Applications

The Increasing Complexity of Consumer Electronics is Driving Demand for Pin Materials with Superb Conductivity and Reliability

Fisk wire is particularly well-suited to support the miniaturization of consumer electronics with a wide range of alloys available in extremely fine gauges. Wire’s greater mechanical strength (in relation to strip), its inherent flexibility, and stellar performance when configured as a stranded cable, allow for achieving precise combinations of conductivity and spring properties in ever-smaller spaces, and without sacrificing quality or performance.

Copper Alloy Wire

Copper alloy wire has a storied history, yet the pursuit of exceptional quality and unwavering reliability in robust applications has remained a rare achievement. Fisk leads the way in the realm of enhanced, high-performance materials crafted to address intricate engineering challenges resulting in a multitude of pioneering processes and products. We are driven by the unwavering belief that our innovations will continue to reshape the landscape, making excellence the new standard in copper alloy wire applications.

Fine Wire

Our efforts in specialty and fine wire focus directly on the ever-increasing requirements for high performance products at smaller sizes. From traditional spring materials in beryllium copper, to alternative beryllium-free systems, our specialty and fine wire products bring together our existing alloy and conductor lines to offer unique combinations of strength, conductivity, formability, and resistance to relaxation or softening. With careful consideration of these attributes and a complete range of available plating solutions, we can meet the requirements of a wide variety of parts from electronic contacts to mechanical springs.
