High Electrical Conductivity Platings

When it comes to electrical conductivity, metals rank in order from most to least conductive: Silver, Copper, Gold, Aluminum, and Zinc. Silver stands out as the most electrically conductive metal among these.

In wet processes, materials can be plated with silver, copper, and gold. However, aluminum cannot undergo plating in wet processes. This limitation stems from aluminum's susceptibility to oxidation when exposed to air in normal environments, making it unsuitable for contacts and connectors due to potential corrosion.

Depending on the specific application requirements, contacts, and connectors often utilize gold, silver, tin, palladium, or palladium alloy plating. These plating materials offer varying degrees of electrical conductivity, corrosion resistance, and durability, catering to the diverse needs of electronic components and systems.
