Nickel Silver Alloy Foil (Cu62/Ni18/Zn20)

Formula: Cu 62/Ni 18/Zn 20
Form: Foil/Film/Sheet
Material: Nickel Silver Alloy
Commodity: Alloys
Nickel silver alloy foil (Cu62/Ni18/Zn20) from Goodfellow makes for an excellent foil material due to its distinct material properties. With good corrosion resistance and high thermal conductivity, this nickel silver foil has become popular for a variety of applications. The alloy's corrosion resistance allows it to be used as a protective coating for reactive metals. Its high thermal conductivity also makes this foil useful for heat transfer applications. As part of Goodfellow's extensive range of metals, this nickel silver alloy adds unique capabilities while retaining the malleability of traditional foil materials.
