Nickel Silver is an electronic-grade alloy with high thermal and electrical conductivity characteristics. Despite the alloy’s name and shiny appearance, it contains no Silver. Primarily comprised of Copper, Nickel and Zinc, Nickel Silver is hard, malleable, ductile, corrosion resistant and non-magnetic. The usual formulation is 60 percent Copper, 20 percent Nickel, and 20 percent Zinc. The alloy we most often use is Alloy 770 (55% Cu, 18% Ni, 27% Zi).
Fotofab proudly services the US & International customers.
Fotofab utilizes a chemical etching process to produce designs that can withstand harsh indoor and outdoor environments. The etching process uses an acid (Ferric Chloride) to cut into unprotected parts of a metal surface to create a design or image. Our etched projects can be machined and formed to your project’s specifications.
- Has a silvery-white color
- It’s hard, malleable, ductile and nonmagnetic
- Exhibits anti-galling properties
- It resists corrosion
- Excellent cryogenic performance
- When exposed to oxygen for long time periods, Nickel Silver develops a protective oxide or patina that turns brownish-green
- Ideal for welding and soldering with the addition of lead
Nickel Silver Etching Applications:
By varying the levels of Copper, Nickel, Zinc and other metals in Nickel Silver formulations, the alloy can exhibit differing levels of electrical conductivity, corrosion resistance and appearance. As a result, Nickel Silver is used in a variety of applications. Examples include:
- Audio components
- Marine fittings
- Food and sanitation fittings
- Lead wires
- Fuel cells
- Battery casings
