History

More Than 125 Years of Precision Manufacturing Excellence

Since its founding in 1901, Sigmund Cohn Corp. has built its reputation on one guiding principle: manufacture precision metal products that customers can trust without compromise.

Founded by Sigmund Cohn, the company quickly became known for producing high-quality precious metal products with exceptional consistency, purity, and craftsmanship. More than a century later, that same commitment continues to define every product we manufacture and every customer relationship we build.

Advancing Technology Through Material Innovation

As technology has evolved, so has Sigmund Cohn.

Our history closely parallels many of the world's most important engineering advancements. During the development of implantable cardiac pacemakers, Sigmund Cohn was already supplying precision platinum alloys that helped make long-term implantable medical devices possible through their exceptional biocompatibility and corrosion resistance.

As aerospace exploration, scientific research, semiconductor manufacturing, and advanced sensing technologies expanded, our precision wire and specialty alloys became integral components in increasingly sophisticated systems. From cardiovascular and neurovascular devices to aerospace instrumentation, automotive safety systems, thermocouple wire, RTDs, and precision electronic components, our materials have continually supported innovations that demand exceptional reliability.

Throughout every generation of technological advancement, one principle has remained unchanged: engineering challenges drive material innovation.

Four Generations of Family Leadership

Today, Sigmund Cohn Corp. remains a fourth-generation family-owned manufacturer led by President Thomas Cohn, the founder's great-grandson.

While manufacturing technologies, analytical instrumentation, and quality systems have continually advanced, our commitment to precision manufacturing, exceptional customer service, and engineering collaboration remains exactly as it was in 1901.

Our manufacturing capabilities now include precision wire, flat wire, ribbon, strip, seamless tubing, proprietary platinum alloys, custom precious metal fabrication, coin blank planchets, and value-added processing that supports customers from prototype development through full-scale production.

Building Long-Term Partnerships

For more than 125 years, engineers, OEM manufacturers, and procurement professionals have trusted Sigmund Cohn because we understand that every material specification influences product performance, manufacturing efficiency, regulatory compliance, and long-term reliability.

Today, we continue that legacy by combining metallurgical expertise, precision manufacturing, collaborative engineering support, and rigorous quality control to help customers solve complex manufacturing challenges with confidence.

As technologies continue to evolve, our commitment remains the same: deliver precision materials and engineered solutions that perform when failure is not an option.
