Silver Wire from Goodfellow is a pure silver conductor with high electrical and thermal conductivity. The wire has a bright, shiny appearance and is very malleable and ductile. With the highest electrical conductivity of any metal, silver wire is commonly used for electrical applications requiring minimal resistance, including electronics, solar panels, and small appliances. It also has excellent thermal conductivity, making it useful for heat transfer in cryogenics, thermoelectric devices, and other specialized applications.
