The Sigmund Cohn Difference
Precision Manufacturing. Engineering Expertise. Proven Performance.
Choosing a precision metal supplier is about far more than purchasing material. It is about partnering with a manufacturer that understands how metallurgy, manufacturing processes, and application requirements influence the performance of your finished product.
For more than 125 years, engineers, OEM manufacturers, and procurement professionals have trusted Sigmund Cohn Corp. to manufacture precision precious metal and specialty alloy products that consistently meet demanding performance requirements. Across industries including medical devices, aerospace and defense, automotive, electronics, sensing and control, temperature measurement, industrial manufacturing, and sovereign coinage, our products are engineered to perform where failure is not an option.
We Solve Engineering Challenges, Not Just Material Requests
Every application presents unique electrical, thermal, mechanical, and manufacturing challenges. Selecting the proper alloy requires balancing conductivity, tensile strength, corrosion resistance, biocompatibility, radiopacity, dimensional stability, operating temperature, manufacturability, and cost.
Rather than simply supplying a catalog material, our engineers and metallurgists evaluate your complete application, including performance objectives, environmental conditions, tolerances, fabrication requirements, secondary processing, and production volumes. We then recommend the material and manufacturing approach that delivers the best long-term performance.
In many cases, the optimal answer is one of our proprietary platinum alloys or a customized manufacturing process developed specifically for your application.
Precision Manufacturing from Raw Material to Finished Component
Manufacturing consistency is essential when components must perform identically from prototype through full-scale production.
Sigmund Cohn controls every critical stage of manufacturing through an integrated ISO 9001:2015-certified quality management system. From alloy production and wire drawing to rolling, tubing, plating, precision fabrication, inspection, and testing, every process is carefully monitored to ensure exceptional quality, dimensional accuracy, and repeatability.
This integrated manufacturing approach provides:
Consistent lot-to-lot material performance
Complete material traceability
Faster product qualification
Simplified supply chain management
Reliable long-term production support
More Than a Century of Metallurgical Innovation
Few manufacturers possess the depth of metallurgical expertise developed over more than a century of continuous precious metal manufacturing.
Our proprietary alloys, including Platinum #479® and Platinum #851®, were engineered to achieve electrical, mechanical, and radiographic performance levels beyond those available from conventional alloys.
Combined with our application engineering support, custom fabrication capabilities, and precision manufacturing expertise, this knowledge enables customers to optimize both product performance and manufacturing efficiency.
"The worldwide precious metal industry has experienced tremendous change over the years, yet Sigmund Cohn Corp. has remained committed to the vision established by my great-grandfather: to provide the highest quality products, exceptional service, and lasting value to every customer. Our ISO 9001:2015 certification reflects that commitment, but it is our people, experience, and dedication to precision manufacturing that truly set us apart."
