Fine Wire

Ultra-Fine Wire for Miniaturized Medical, Electronic & Sensor Application

As devices continue to shrink, manufacturing precision becomes increasingly important. Ultra-fine wire must maintain exceptional dimensional consistency, surface quality, electrical performance, and mechanical integrity while measuring only a fraction of a millimeter in diameter.

Sigmund Cohn Corp. specializes in manufacturing ultra-fine precious metal and specialty alloy wire as small as 0.0003 inches, supporting applications where even microscopic imperfections can affect product performance.

Maintaining this level of precision requires advanced metallurgy, tightly controlled drawing schedules, precision tooling, carefully managed annealing cycles, and rigorous inspection throughout production. These capabilities allow us to consistently manufacture ultra-fine wire that performs reliably in highly regulated and mission-critical applications.
