Silver plating offers the highest electrical conductivity of all metals. It is not an inert metal and will oxidize rapidly. Silver plating is best suited for engineering purposes for electrical contact characteristics, high electrical and thermal conductivity, thermo-compression bonding, wear resistance of load-bearing surfaces, good corrosion resistance and good solderability. Below is the most common specification for silver plating.


Type I – Matte

Type II – Semi-Bright

Type III – Bright


A – With supplementary tarnish-resistant treatment

B – Without supplementary tarnish-resistant treatment
