The sealing / controlled expansion alloys are Iron-Nickel based. They are used for numerous
applications that require...

... controlled expansion in a range of temperatures
... hermetic sealing / sealing glass
... high reliability and superior mechanical properties.

We custom re-roll these grades from stock, to your specific thickness, temper and width
requirements. We primarily supply in Coil form, but can also provide cut-to-length Strip in
certain situations. We supply DFARS-compliant certs, included with every order.

... gauge or temper that your usual distributor doesn't have, or
... minimum order quantity lower than your re-roller's MOQ, or
