Precision Wire

Precision Wire Engineered for Critical Application

When performance depends on the smallest manufacturing detail, precision wire becomes a critical engineering component, not simply a raw material.

Whether used in implantable medical devices, aerospace sensors, thermocouples, automotive safety systems, or precision electronic assemblies, wire must deliver consistent electrical, thermal, and mechanical performance throughout every production lot. Even slight variations in diameter, alloy composition, surface finish, or grain structure can impact calibration, electrical resistance, fatigue life, and long-term reliability.

For more than 125 years, Sigmund Cohn Corp. has manufactured precision wire for engineers and OEM manufacturers developing high-performance products for the world's most demanding applications.

We manufacture precision wire from platinum, platinum alloys, gold, silver, nickel, copper, thermocouple alloys, resistance alloys, and other specialty metals. Through tightly controlled drawing, heat treatment, and inspection processes, we manufacture precision wire with exceptional dimensional accuracy, consistent mechanical properties, and repeatable performance, supporting projects from prototype development through high-volume production.
