When it comes to plating metals, you have a wide array of options to consider. Each option boasts different benefits, and so it is important to keep in mind that no two options are the same. After selecting a base metal and a stranding technique, plating is used as an option for customizing and maximizing the properties of a conductor. Plating is considered a relatively inexpensive means of combining the unique advantages of two different metals.
The shield of a multi-conductor and conductor cables are frequently made with copper or copper-based alloy as a base metal because copper is highly conductive and has greate mechanical performances all at a reasonable cost. Alloy beryllium copper wire is an excellent choice for many applications, but there are many reasons not to use it. If an application needs solderability, has a great temperature range, and strong resistance to corrosion, beryllium copper straight and cut wire is not enough. Those problems are circumvented with plating.
We use a variety of metals too for plating because each type offers its benefits. Learning about plating options ensures you maintain the highest levels of manufacturing.
Straight and Cut Wire
Tin is commonly used to coat copper and copper alloys because of their low-cost and solderability. Tin improves chemical and corrosion resistance as well.
Silver, although less commonly used, offers extremely high conductivity. It will reduce the resistance of a plated wire. Consider using silver for applications that produce high frequencies.
Nickel is much harder than the two above metals, but it is commonly used for adding resistance and ability in high temperatures.
