  • Gold: The Only Metal Used in All Major Industries

Gold has historically proved to be the most precious metal for nearly all human cultures and civilizations due to its many qualities as well as its intrinsic value. Gold is many things; extremely ductile and malleable, electrically conductive, stainless, and easily mixed with all other metals. Gold is used today in all forms to adapt to modern lifestyle needs.

The rarity, usefulness, and desirability of gold makes it a substance with long-term value. Gold works well because it has a high value, is durable, portable, and easily divisible. Many people limit the usefulness of gold to the financial industry for paper currency reliability, coinage, bullion, and investment backing. Due to its desirable yellow color and high luster, plus its resistance to tarnish and its ability to be cast into all possible shapes, 78% of the gold mined every year is used within the jewelry industry. In this article, however, we would like to highlight the importance of gold across industries.

Gold in Electronics

Gold meets the requirements of high quality and reliable performance better than any other metal. Gold is the highly efficient conductor used in connectors, switch and relay contacts, soldered joints, connecting wires and connection strips. A small amount of gold is used in almost every sophisticated electronic device, including cell phones, calculators, personal digital assistants, global positioning systems (GPS), televisions, computers, and other small electronic devices. Nearly one billion cell phones are produced each year, and most of them contain about fifty cents worth of gold. Full-year gold demand in the technology space reached 334.6 tonnes in 2018, the highest since 2014.

Gold in Dentistry

Gold’s use in dentistry dates back as early as 700 B.C. due to its superior performance and aesthetic appeal. Gold is chemically inert, nonallergenic, and easy to work with for dentists. Gold alloys are used for fillings, crowns, bridges, and orthodontic appliances. Today, the amount of gold used in dentistry is starting to rise again since it has been proved that less inert metals may have an adverse effect on long-term health. Full-year gold demand in dentistry has reached 15.4 tonnes in 2018.

Gold in Aerospace

Gold is used in every space vehicle launched by NASA. It is used in hundreds of ways to meet the highest standards of lubrication, maintenance, and building materials. Also, it is used as a dependable conductor and connector. Many parts of space vehicles are fitted with gold coated polyester film inorder to reduce radiation and help stabilize the temperature of the spacecraft. A very thin film of gold is used within the helmet’s visor of an astronaut’s space suit in order to protect the astronaut’s eyes and skin from intense solar radiation. Gold is also used as a lubricant between mechanical parts, since organic lubricants would volatilize, and they would be broken down by the intense radiation beyond Earth’s atmosphere.

Gold in Glassmaking

Gold has many uses in the production of glass, especially for its pigmentation that produces a rich ruby color. Gold is also used for climate-controlling purposes. It reflects solar radiation outward to keep buildings cool in the summer, and it reflect internal heat inward to help them stay warm in winter.

Gold is the most reliable metal. It has been used on the crowns worn by kings and in the most essentials materials in many industries. Gold, beside its high esteem and status, has proved its value throughout history with its many unique and positive qualities.
