The Strategic Use of Plating Pure copper, while an excellent conductor, can be too soft for certain demanding mechanical applications. Copper is relatively abundant and cost-effective, which allows it to be used in everything from building wiring and power transmission lines to the intricate traces found on computer motherboards.
Platinum Group Conductivity Comparison: Ranking Electrical Performance
It is not the most conductive element, but it is highly valued for its resistance to oxidation and corrosion. Given the cost of solid gold components, the metal is almost always applied as a thin electroplated layer over a base metal like copper or nickel.
This exceptional property is why high-end RF connectors, specialized audio equipment, and satellite components often specify silver plating or silver-based alloys despite its premium price point. Cost Dilemma The primary reason silver is not used for widespread wiring is its economic cost and relative scarcity compared to base metals.
Platinum Group Metals Conductivity Compared to Silver and Copper
Its atomic structure allows electrons to flow with minimal resistance, making it the standard by which all other conductors are measured. Alloying for Durability Pure copper, while an excellent conductor, can be too soft for certain demanding mechanical applications.
