Applications include wire stock and electrical connections (such as Insulation-displacement connectors).
Many gold nuggets are formed by cold welding in nature since gold has no protective oxide skin to inhibit junction formation. They form in streams and rivers by impact action from stones carried by the flow of water on the tiny flakes of gold washed from deposits upstream. Owing to the high density of gold, they tend to remain in pockets in the bed of the stream where further flakes are thrown and aggregate with the growing nuggets. Such nuggets can grow to very large sizes and are highly prized by prospectors.
