Tests have shown that this plating of alloy is resistant to a wide variety of corrosive agents and is in the same class as chromium plate.
The alloy plate is electrochemically noble to steel, with a potential close to that of copper. On steel, an undercoating of about 0.0005 inch of copper, followed by plating with the tin-nickel alloy provides good resistance to corrosion. |
