Recycling Silver Cadmium Oxide Scrap

When you think about recycling precious metals, you probably think first about gold, silver, and platinum. That’s good thinking. If you have items that contain those metals, you could be sitting on a lot of money.

But have you also stopped to ask whether the items you have on hand contain quantities of silver cadmium oxide? It is often overlooked – it is easy to overlook – but it can contain quantities of silver and cadmium that are quite valuable.

Where Can You Find Cadmium Silver Oxide?

Short answer. If you own almost any kind of electronic scrap, you probably own quantities of silver cadmium oxide. It is widely used in motors, switches, relays, and electrical contacts.

Why is Silver Cadmium Used in Electronic Devices?

Silver cadmium oxide is used because it possesses two seemingly contradictory positive traits. First, it is a very good conductor of electricity. Second, it is arc-resistant (it inhibits the tendency of electricity to arc between contacts when they are open). Those two traits make it an ideal material for use in switches and other applications, especially where high electrical loads are present.

What Will My Scrap Look Like?

Silver cadmium oxide can be found in old electrical-powered manufacturing equipment like motors, switches, relays, and brazed contact assemblies. But it is also found in materials that are used to manufacture those items – materials like silver-cadmium oxide wire, sheets, strips and tapes.

How Much Cadmium Is in My Scrap?

The answer is, it depends. Silver cadmium oxide contacts generally contain between 10% and 25% cadmium. How can you tell what you have? Send us a sample of what you have for testing. Call us at 800-426-2344 to learn more.
