Electroplating is a process that uses electric current to add a coating of specified metal to wire. The coating of the chosen metal adds properties to the underlying product Resistance to corrosion, conductivity, and aesthetic quality are some of the benefits of plating wire.
1) Why gold plating is so popular/common.
Gold is simply the best conductor for required springs, pins and connectors.
2) Does nickel-plating work well with different plating technologies?
Nickel functions like a barrier that is between the base substrate and the finish (applied over the nickel layer). Nickel will help prevent the composition of the base metal from affecting the performance of the finish.
3) Is nickel better than tin?
Both have different characteristics, and so it is important to acquire wire that is designed to fit your exact needs. For instance, nickel has little solderability, and forming nickel may crack under stress. Nickel is known to grow heavy oxide, and it is less conductive than tin. In many cases, tin is the appropriate material.
4) Why has silver plating become so common?
Silver is the less costly plating material with similar characteristics to gold. Silver, however is vulnerable to tarnishing which over time will lead to less certain performance and conductivity.
5) Beryllium copper
Beryllium copper alloys are frequently used because of their ability to combine hardness, corrosion resistance, and strength. This material has advantages that cannot be found in steel. For instance, beryllium copper has a higher thermal and electrical conductivity when compared to steel. Beryllium also has non-sparking qualities. It is also non-magnetic, which means the material can be used in many places. Beryllium copper is heat treatable, which helps to add strength to the finished product. Lastly, the alloy can be formed into wires or strips.
