Silver Plating
Mitsuya has provided advanced engineering solution service for various industrial silver platings.
Silver (Ag) is the best conductor among metals and shows the lowest electrical resistivity.
Silver (Ag) plating is used as functional plating for electronic components.
At Mitsuya, we have three types of Ag plating
・Matte Silver (Ag)
・Bright Silver (Ag)
・Hard Silver (Ag)
Properties of Silver (Ag) Plating
・Highest electrical conductivity
・Lowest electrical resistivity
Hardness of each type of Silver (Ag) plating
・Matte Ag ~Hv70
・Bright Ag ~Hv100
・Hard Ag ~Hv155 (-5/+15)
Features of various types of silver plating
Bright silver plating
・Connectors
・Terminals
・Switches
Matte silver plating
・IC lead frames, etc. because of its excellent conductivity, bondability and solderability.
・Bearings and other components as an individual lubricant film that prevents galling and utilizes lubricating properties.
Hard silver plating (with excellent wear resistance)
・Electric Vehicle (EV),
・Plug-in Hybrid Vehicle (PHV)
・Used on charging terminals for electric vehicles (EVs) and plug-in hybrid vehicles (PHVs), and other related products.
The only disadvantage of silver plating is that it tarnishes easily. Silver plating is particularly susceptible to sulfuric substances, which can cause silver sulfide to form and turn black.
