A plating film suitable for functional parts with few pinholes.
DIALLOY 822 is an alkaline cyanide-type tin-zinc alloy plating solution. It can be applied to barrel plating and rack plating. The alloy composition is 80% tin and 20% zinc under standard conditions, but the alloy composition can be adjusted by changing the working conditions. The plating film obtained with DIALLOY 822 is ideal for functional parts. It imparts corrosion resistance to iron and iron alloys and contributes to wear prevention with good sliding properties. By adding post-treatments such as passivation and sealing, corrosion resistance can be further enhanced. The plating film exhibits excellent solder wetting and weldability.
