Copper Clad Nickel-Iron Alloy (Dumet)

Dumet is a copper clad nickel-iron alloy widely used to obtain hermetic seals in soft glass. This is possible because the thermal expansion of Dumet closely matches that of glass, and the material "wets" well, effecting the bond with the glass. Dumet is commonly supplied electroplated with gold, tin, or solder
