配方类型：	METALS
配方说明：	Tin-Nickel Alloy Plating
配方组成：	Density/amp/sq ft Ammonium Bifluoride/35 Nickel Chloride/300 Temperature/150F Cathode Sodium Fluoride/28 Stannous Chloride/27 Current/About 25
配制方法：	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.
