The EXPERTS In Precious Metal Alloys, Electrical Contacts, & Precious Metal Components

At Deringer-Ney, we design and produce precious metal wire, strip, and rod. We also manufacture precision specialty metal parts for a wide variety of applications. We are the inventors of the globally renowned Paliney® and NeyoroTM precious metal alloys.  Our products are in millions of devices used worldwide including medical equipment, portable medical devices, semiconductor test equipment, automobiles, switches, appliances, sensors, electronics, and many others.  

Our custom noble alloys have expanded capabilities in neurostimulation, implantable devices, medical diagnostics, semiconductor fab and test, and many other technologies. And we’re continuously inventing more. We provide the alloys as raw materials and also make fabricated parts and assemblies. Since most of our alloys contain precious metal, we recycle internally resulting in better cost control.

We are one of the world’s largest producers of custom electrical contacts and contact assemblies for switches and controls requiring high strength, high nobility, and long service life in harsh environments. We make these contacts by cold forming, automatic welding, automatic staking, and brazing. We also produce continuously welded contact tape and tape cutoffs.  Learn more about how to design contacts with the Deringer-Ney online Electrical Contact Manual.

Our world-renowned R&D department, along with our experienced technical staff, provides innovative design and engineering solutions. We help customers invent new devices and solve performance problems using our alloy technology and our expertise in precision manufacturing. We routinely assist in cost reduction through intelligent design and provide ROHS assistance.

Our in-house manufacturing capabilities include precision cold forming, complex precision machining, stamping and microstamping, metal forming, and metal joining. We also offer contract assembly at our facility in Nogales, Mexico. Our micro manufactured parts push the technical envelope.  The market continually demands smaller and more reliable devices and Deringer-Ney proves to meet or exceed these requirements time and again.
