Gold (Au) is a precious metal that has been used for coinage, jewelry, and other arts throughout recorded history. Due to its properties like excellent electrical and thermal conductivity, chemical inertness and oxidation resistance, gold film is widely used in various electronic, magnetic and optic devices in recent years.

Our standard size is 3mm Diameter x 3mm Length.
