Real gold is essential in the manufacture of the vast majority of the computers, electronics and and smartphones to enable the trading of crypto currencies
Gold is used for making electronics as precious metals conduct electricity well and do not rust/corrode. Electrical resistibility of gold is the lowest of all metals, except for silver and copper. But silver and copper readily tarnish causing contact resistance to increase. For low current, low voltage conditions and low contact force, gold is often the best choice technically and in some applications such as automotive RF connectors and MEMS switch contacts, it is the only choice.
Electrical compounds made with gold are highly reliable, we can find them in cell phones, laptops, computers, screens, GPS units, calculators, and other small and large electronics.
The biggest challenge is to recover gold from the devices. The amount of gold used for the compounds is very low and it is hard to recycle the devices and recover the gold from them. That means there is ever less gold available for easy use in the world.
Gold is used for medical purposes as well being found in many devices which are used in healthcare, gold has been used for medical treatments.
Gold is used because it is chemically inert, non-allergic, easy to mold and work with and its aesthetic appeal when used for fillings, crowns, bridges and orthodontic appliances.
Gold is also used to treat some medical conditions such as cancer, arthritis and other specific uses. such as in aerospace because when sending something into space you want to make sure to make it out of the most quality materials. so gold is used in space shuttles, the metal is used in circuitry as a connector and conductor, gold-layered polyester film is applied in spacecraft helping with temperature stabilization and infrared radiation reflection.
Gold is used in the production of glass, one of them being because of aesthetics and because of usefulness, a small quantity of gold is used in glass as it is annealed to get its beautiful ruby colour and also for making glass for climate-controlled buildings, gold also added to the visor on astronauts’ helmets, as it protects them from infrared radiation.
Emerging new uses for gold are nanotechnology, pollution reduction in air and water, fuel cells and lithium-ion batteries, and in solar cells.
Gold is too expensive to be used lightly and only when there is no possibility of finding another less expensive substitute.
Except for jewellery making, the way we use gold today was mostly developed in the last 20-30 years, although the need for gold and its qualities for making new technologies will most likely continue as there are very few substitutes, although supply is increasingly limited.
