When precision wire becomes part of an implantable medical device, aerospace sensor, automotive safety system, or industrial control application, product quality directly affects system performance and reliability.

At Sigmund Cohn Corp., quality is built into every stage of manufacturing. It is not simply inspected at the end of the process.

Our ISO 9001:2015-certified quality management system combines advanced analytical testing, statistical process control, documented manufacturing procedures, and decades of manufacturing expertise to ensure every product consistently meets customer specifications.

Certificate number C2026-01088, issued by Perry Johnsons Registrars Inc., accredited by ANAB. Current through March 1, 2029. Download our ISO 9001:2015 certificate or verify it independently.

Built for Critical Applications

Our quality program includes:

• Precision manufacturing to exact dimensional and compositional tolerances
• Complete traceability from raw material through finished product
• Comprehensive inspection and testing throughout production
• Statistical process control for manufacturing consistency
• Analytical verification of purity, resistivity, tensile strength, and other critical material properties
• Continuous process improvement focused on customer satisfaction

Our ISO 9001:2015 system supports customers operating under ISO 13485 and AS9100 requirements, and we supply the Certificates of Conformance, Certificates of Analysis, material test reports, and lot traceability documentation those systems depend on.

This disciplined approach enables engineers to confidently qualify our materials while providing procurement teams with the documentation and consistency required for regulated manufacturing environments.

Our customers depend on predictable performance because their customers depend on them.
