铜或铜合金镀银 - 银质性质
镀银铜或铜合金是一种高效的饰面，用于在宽呼吸的行业中使用热量和电力。自1800年代后期的电气开关设备和传递电流的其他部件以来已应用。近年来，包括连接器和终端的铜电子元件的镀银在电子，汽车和电动车辆（EV）市场内迅速生长。镀银有许多独特的properties这使得这些应用程序是可取的。主要原因是银具有任何金属的最高电和导热率，这有利于电力和热量的有效传输。此外，银是一种相对柔软的金属，使银沉积物围绕配合连接器压缩和形成填充小空隙和微粗糙度。这增加了有效接触面积，导致整体连接器电阻较少。

银ver has excellent lubricity and resists galling in switching, sliding or rotary applications. However, high pressure wear surfaces such as blade-style stab connectors can be susceptible to silverwear. In applications such as this, a higher deposit thickness of silver is recommended as well as the use of a nickel or electroless nickel underplate. Thinner silver plating without a nickel underplate is best used on static joints or low duty cycle connectors that are mated and unmated relatively infrequently.
