Silver Plate - Bright and Matte
Pure silver is the most electrically conductive metal known to man. Silver plating may be mirror-bright or matte. Bright and matte silver offer excellent solderability and ductility
Bright silver is plated to obtain an excellent combination of visible light reflection, heat conductivity and electrical conductivity. Bright silver can be as hard as 200 on the Knoop scale, offering good wear resistance
Matte silver is the purest, most ductile, most solderable and most electrically conductive silver deposit. Matte silver is very soft, registering about 80 on the Knoop hardness scale.
