About Us

Precision Precious Metal Manufacturing Since 1901

For more than 125 years, Sigmund Cohn Corp. has helped engineers transform complex design challenges into high-performance, manufacturable solutions through precision precious metal and specialty alloy manufacturing. Since 1901, we have partnered with OEMs, medical device manufacturers, aerospace companies, industrial manufacturers, and technology innovators to produce precision-fabricated wire, ribbon, strip, seamless tubing, coin blank planchets, and custom metal components engineered for the world's most demanding applications.

When component performance cannot be compromised, manufacturers rely on Sigmund Cohn. Our precision materials are found in implantable medical devices, minimally invasive surgical instruments, aerospace and defense systems, automotive safety technologies, precision sensors, temperature measurement devices, electronic components, and sovereign coinage. Every product is manufactured to exacting standards for purity, dimensional accuracy, and repeatable performance.

Engineering Begins with Material Selection

Selecting the right material is often the difference between a component that performs reliably for decades and one that fails prematurely. Electrical conductivity, corrosion resistance, biocompatibility, radiopacity, tensile strength, thermal stability, and manufacturability must all be carefully balanced to meet demanding application requirements.

Our engineers and metallurgists work alongside your engineering, manufacturing, and procurement teams to identify the ideal alloy, product form, tolerance, surface finish, and secondary processing required for your application. Whether you're developing a proof-of-concept prototype or qualifying a high-volume production program, we help ensure every material decision supports long-term product performance and manufacturing efficiency.

Precision Manufacturing That Delivers Consistency

Manufacturing precision is what separates a material supplier from a true engineering partner.

Sigmund Cohn manufactures precision wire as small as 0.0003 inches in diameter and produces flat wire and ribbon as thin as 0.0002 inches, with width-to-thickness ratios up to 75:1. Our advanced
manufacturing processes maintain exceptional dimensional consistency, alloy composition, and mechanical properties from lot to lot, ensuring critical components perform exactly as designed.

This level of manufacturing control is essential for applications such as:

  • Implantable medical devices requiring biocompatibility and radiopacity

  • Platinum RTDs and thermocouple wire requiring precise electrical characteristics

  • Aerospace instrumentation operating in extreme environments

  • Automotive sensors and safety systems requiring consistent performance

  • Precision electronic components where dimensional variation cannot be tolerated

Supporting Every Stage of Production

Our value extends well beyond supplying raw materials. Sigmund Cohn integrates engineering support, precision fabrication, secondary processing, and quality assurance into a single manufacturing solution.

By working closely with customers throughout product development and production, we help simplify supply chains, reduce qualification time, improve manufacturing consistency, and lower total production costs. Engineers benefit from collaborative application support, while procurement teams gain confidence in supply continuity, traceability, and dependable quality.
