Used as reducer of chemical plating. Characteristics: Form film with crystal form(not random pile) on the metal surface. So the Ni-B formed in nickel plating has the strong points of fastness, conductivity. Film can be formed on the internal wall of plastic tube and plastic board£¨printed circuit board. It is suitable to other noble metal besides nickel

在在化学镀中用作为还原剂。其特点是在金属表面形成一晶形薄层而非通常的无规堆积。因此在镀镍时形成的Ni-B镀层具有坚牢度高、导电性好的优点。可在塑料管内壁及塑料板面（印刷电路板）形成薄层。除镍外其他贵金属同样适用。
