Industries served since 1901
Processes perfected over a century
For over a century, Sigmund Cohn Corp. has refined its manufacturing processes, building on industry standards and our own research and development.
- Wire drawing, rolling and annealing
- Seamless tubing and precision fabrication
- Electroplating, enamelling and secondary processing
- Prototype through full production volumes
Only the best materials
Since 1901 we have sourced the purest forms of earth's natural metals — platinum, gold, silver and palladium, alongside specialty and base metal alloys engineered for specific resistivities, tensile strengths and degrees of nobility.
- Platinum to 99.995% purity, including Reference Grade
- Gold from 99.98% to 99.999%
- Platinum-rhodium thermocouple alloys, Types R, S and B
- Proprietary alloys including Platinum #479® and #851®
Where failure is not an option
Our 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.
- Guidewires, marker bands and implantable electrodes
- Thermocouple wire and platinum RTDs
- Airbag initiators and spark plug electrodes
- Bonding wire, sputtering targets and slugs
Available in every market
Expanding into new industries year after year, Sigmund Cohn Corp. has pioneered manufacturing techniques and products across approximately twenty industries.
Medical devices
Radiopaque and biocompatible platinum alloys for interventional and implantable devices.
Aerospace & defense
High-temperature and corrosion-resistant alloys for instrumentation and fusing components.
