2017-9-26 Gold is a typical example of the noble metals, which found application in the electronics industry. Gold is resistant to corrosion in air and in other gaseous environments, so that the contact area contacts made of gold metal is always clean, and its electrical and thermal conductivity is close to silver. Despite these advantages, the contacts of pure gold used in practice only rarely. The main drawback besides high cost, their low hardness, which causes deformation of the contacts even when using low thrust and considerable transfer of material between the contact surfaces in their switching. Gold contacts were applied only in cases where the contact force is very small and the switching currents do not exceed a few milliamps. As with silver increases the hardness of gold added other metals (Ag, Cu, Pt, Ni, Zr). Given the higher mechanical properties and lower cost to find the binary, respectively. Ternary alloys of gold

2016-2-11 This is not the most recent advance in gold extraction, however. Recently, a research team discovered an efficient method of stripping gold from electronic wastes. Modern electronics contain very small parts that are powered by low currents. As a result, a reliable, corrosion-resistant metal is necessary for the devices to work.
