Beyond its popularity in the jewellery sector and as a store of value for investors and savers, gold is a precious metal whose physical properties give it a wide range of industrial applications, from electronics to medicine.

Throughout history, gold has been regarded as the ultimate store of value, making it an essential asset for individuals seeking to protect their savings and investors seeking to diversify their portfolios in economic uncertainty.

Its intrinsic value comes from its durability and relative scarcity. However, it is also due to a large and sustained demand from various sectors, from central banks and private investors, who accumulate bullion and coins of this precious metal, to the jewellery industry. Its physical properties also make it highly versatile enough for various industrial applications, for example: 

• Electronics industry. Gold has excellent electrical conductive qualities, as well as very good resistance to corrosion and oxidation. This makes it an ideal metal for use in electronic components, such as connectors, chips and integrated circuits found in computers and mobile phones. It is estimated that around 300 tonnes of gold are used in electronic components every year, and that 7% of the world’s gold is found in such devices.
• Automobiles industry. Apart from being used in electronic components, the automotive industry takes advantage of the excellent quality of gold as thermal insulation to prevent high temperatures from damaging the mechanics of F1 cars and supercars from brands such as McLaren and Koenigsegg.
• Aerospace industry. Just as it is prized in the automotive industry for its thermal protection, and beyond its use in electronic components, the aerospace industry uses gold leaf to coat parts of aircraft engines, satellites, and space capsules to protect them against extreme temperatures and radiation. Gold is also used as a component of aircraft windscreen coatings to help reflect infrared radiation.
• Medicine industry. Because it is non-reactive and non-toxic, gold is used in prostheses and implantable medical devices, such as pacemakers. On the other hand, gold nanoparticles are used in biomedicine in diagnostic techniques for the detection of cancer cells. They are also used in the treatment of rheumatoid arthritis and muscle pain.
