Precious Metals & Technology: How are they related?

While technology has made our lives easier, faster, better, and more fun, it has also impacted the world of precious metals in many ways.

The World Gold Council has released its latest report on the demand for gold in the technology sector. The point is that after a slight decay in 2020, we are seeing a resurgence in using gold in electronics. In addition, other precious metals, such as copper, lithium, and cobalt, are vital to electronics, computers, smartphones, tablets, medical devices, power generation and communications infrastructure.

Gold is highly conductive and does not rust, making it a common material in smartphones. It is used as a coating for pins, connectors, and circuit boards. Each device contains only a tiny amount of gold and silver, but the tech industry is a big consumer of gold and silver.

As small of a quantity of gold and silver, it is still a significant amount which is around $21 billion (320 and 7,500 tons, respectively) of gold and silver is used annually to manufacture high-tech products (personal computers, mobile phones, tablets, and other electrical and electronic equipment), states United Nations University.

Regarding the tech sector, the metal content used is categorized into two groups, Rare earth metals and technology metals.


Precious Metals & Technology











Rare earth metals elements

Rare Earth Elements (REE) are 17 elements, including 15 lanthanides; cerium, dysprosium, erbium, europium, gadolinium, holmium, lanthanum, lutetium, neodymium, praseodymium, promethium, samarium, terbium, thulium, ytterbium, yttrium, and scandium. Yttrium and scandium are included among rare earth elements because they often coexist with lanthanides and have similar properties. Since all these elements are metals, they are also commonly referred to as rare earth metals.

Tech metals

Tech metals are generally considered relatively rare metals commonly used in high-tech devices. These high-tech devices range from consumer electronics and medical devices to advanced defence systems.

Some of the most commonly recognized technical metals are cobalt, lithium, tantalum, indium, gallium, niobium, selenium and zirconium. Since the rare earth elements discussed are metals, they can also be considered technical metals.


How are those metals used?

You will find below the most common rare metals and their application:

  • Cerium is used in light bulbs, TVs and ovens.
  • Dysprosium is mixed within alloys used in wind turbines, electric vehicles and nuclear reactors.
  • Erbium is used in lasers and fibre optic cables.
  • Europium is used in light bulbs, nuclear reactors and lasers.
  • Gadolinium is used in magnets, nuclear reactors and magnetic resonance imaging (MRI).
  • Holmium is used in magnets and nuclear reactors.
  • Lanthanum is mixed with alloys that are used in batteries and hydrogen vehicles.
  • Lutetium is used as a catalyst in refineries.
  • Neodymium is used in magnets and lasers.
  • Praseodymium is used in aircraft engines, fibreoptic cables and magnets.
  • Promethium is used in pacemakers and guided missiles.
  • Samarium is used in microwave devices and magnets.
  • Terbium is used in light bulbs, memory devices and x-rays.
  • Thulium is used in lasers.
  • Ytterbium is used in displays, x-ray machines and fibre-optic cables.
  • Yttrium is used in radars and as an additive within alloys used in high-tech devices.
  • Scandium is used for fuel cells and alloys used in jet planes.
  • Cobalt is used in super-alloys, jet turbines and rechargeable batteries.
  • Lithium is commonly used in batteries.
  • Tantalum is used in capacitors, resistors and other electronic equipment.
  • Indium is often used in LCD screens.
  • Gallium is used in integrated circuits, LEDs and semiconductors.
  • Niobium is used in steel alloys that are a part of jet engines and rockets.
  • Selenium is used in photocells and rectifiers.
  • Zirconium is used in nuclear power stations.


Accessibility and trading

Modern technology has dramatically impacted the business world with more data advancement, communications and trade. And the world of bullion is benefiting too. As precious metals support technology, the support is mutual as technology has created more access to it at an unprecedented speed where transactions are sometimes concluded in a matter of seconds between two parties on two extremities of the world.

Not to mention the number of iPhones sold in 2021, we can notice the technology has enhanced communication, mainly where precious metal transactions have been more reactive to any price movement generated by economic and social climates. Buying and selling are very dependent on technology. Internet, of course, but the devices you are using to go online to trade precious metals that contain some gold, silver and many others.

The same advancement in technology has brought many benefits to bullion investors worldwide. Advertisements, education, product and opportunity have become more accessible and give a sense of security as consumer demand is only going higher for more high-tech products.
