Palladium-Nickel alloy plating

Palladium Nickel alloy plating

Mitsuya has developed an improved palladium-nickel alloy plating which has superior properties to pure palladium in the hardness and the wear resistance.
Palladium is inferior in corrosion resistance with activity chemically in the platinum group.
Palladium plating is somewhat dark tone, lacking in vividness. Because of this, it has been used as a base plating of rhodium-plating and gold-plating. Pure palladium is difficult to be plated thickly, too.
Mitsuya developed palladium-nickel alloy plating to make up for these weak points of the palladium plating. Depending on the ratio of nickel, corrosion resistance improves than pure palladium plating, and the pinholes decrease. In addition, the hydrogen embrittlement is hard to occur.
The palladium-nickel alloy plating has higher hardness with Hv450 degree than pure palladium plating. Therefore it is often used for the point of contact part as alternative plating of the gold plating.
Recently, it has been widely used in the products that are required to sliding resistance and insertion resistance.
Palladium-nickel alloy plating of Mitsuya is able to apply to the method of reel-to-reel, barrel, and rack.
