You may play a brass instrument while wearing a white gold necklace – or maybe you cook with a cast iron skillet and store your leftovers in a stainless steel refrigerator. It’s likely that you know these common metal alloys by name, and you can probably even imagine what they look and feel like. But do you know what base metals these alloys are made of, exactly?
Common Metal Alloys
Today’s infographic comes to us from Alan’s Factory Outlet, and it breaks down metal and non-metal components that go into popular metal alloys. In total, 20 alloys are highlighted, and they range from household names (i.e. bronze, sterling silver) to lesser-known metals that are crucial for industrial purposes (i.e. solder, gunmetal, magnox).
Humans make metal alloys for various reasons. Some alloys have long-standing historical significance. For example, electrum is a naturally-occurring alloy of gold and silver (with trace amounts of copper) that was used to make the very first metal coins in ancient history. However, most of the common metal alloys on the above list are actually human inventions that are used to achieve practical purposes. Some were innovated by brilliant metallurgists, while others were discovered by fluke, but they’ve all had an ongoing impact on our species over time.
Alloys with an Impact
The Bronze Age (3,000 BC – 1,200 BC) is an important historical period that is rightfully named after one game-changing development: the ability to use bronze. This alloy, made from copper and tin, was extremely useful to our ancestors because it is much stronger and harder than its component metals. Steel is another great example of an alloy that has changed the world. It is one of the most important and widely-used metals today. Without steel, modern civilization (skyscrapers, bridges, etc.) simply wouldn’t be possible. While nobody knows exactly who invented steel, the alloy has a widely-known cousin that was likely invented in somewhat accidental circumstances. In 1912, English metallurgist Harry Brearley had been tasked with finding a more erosion-resistant steel for a small arms manufacturer, trying many variations of alloys with none seeming to be suitable. However, in his scrap metal heap – where almost all of the metals he tried were rusting – there was one gun barrel that remained astonishingly untouched. The metal alloy – now known to the world as stainless steel – was a step forward in creating a corrosion-resistant steel that is now used in many applications ranging from medical uses to heavy industry. on Did you know that nearly one-fifth of all the gold ever mined is held by central banks? Besides investors and jewelry consumers, central banks are a major source of gold demand. In fact, in 2022, central banks snapped up gold at the fastest pace since 1967. However, the record gold purchases of 2022 are in stark contrast to the 1990s and early 2000s, when central banks were net sellers of gold. The above infographic uses data from the World Gold Council to show 30 years of central bank gold demand, highlighting how official attitudes toward gold have changed in the last 30 years.
Why Do Central Banks Buy Gold?
Gold plays an important role in the financial reserves of numerous nations. Here are three of the reasons why central banks hold gold:
Balancing foreign exchange reserves Central banks have long held gold as part of their reserves to manage risk from currency holdings and to promote stability during economic turmoil. Hedging against fiat currencies Gold offers a hedge against the eroding purchasing power of currencies (mainly the U.S. dollar) due to inflation. Diversifying portfolios Gold has an inverse correlation with the U.S. dollar. When the dollar falls in value, gold prices tend to rise, protecting central banks from volatility. The Switch from Selling to Buying In the 1990s and early 2000s, central banks were net sellers of gold. There were several reasons behind the selling, including good macroeconomic conditions and a downward trend in gold prices. Due to strong economic growth, gold’s safe-haven properties were less valuable, and low returns made it unattractive as an investment. Central bank attitudes toward gold started changing following the 1997 Asian financial crisis and then later, the 2007–08 financial crisis. Since 2010, central banks have been net buyers of gold on an annual basis. Here’s a look at the 10 largest official buyers of gold from the end of 1999 to end of 2021: Rank CountryAmount of Gold Bought (tonnes)% of All Buying #1🇷🇺 Russia 1,88828% #2🇨🇳 China 1,55223% #3🇹🇷 Türkiye 5418% #4🇮🇳 India 3956% #5🇰🇿 Kazakhstan 3455% #6🇺🇿 Uzbekistan 3115% #7🇸🇦 Saudi Arabia 1803% #8🇹🇭 Thailand 1682% #9🇵🇱 Poland1282% #10🇲🇽 Mexico 1152% Total5,62384% Source: IMF The top 10 official buyers of gold between end-1999 and end-2021 represent 84% of all the gold bought by central banks during this period. Russia and China—arguably the United States’ top geopolitical rivals—have been the largest gold buyers over the last two decades. Russia, in particular, accelerated its gold purchases after being hit by Western sanctions following its annexation of Crimea in 2014. Interestingly, the majority of nations on the above list are emerging economies. These countries have likely been stockpiling gold to hedge against financial and geopolitical risks affecting currencies, primarily the U.S. dollar. Meanwhile, European nations including Switzerland, France, Netherlands, and the UK were the largest sellers of gold between 1999 and 2021, under the Central Bank Gold Agreement (CBGA) framework. Which Central Banks Bought Gold in 2022? In 2022, central banks bought a record 1,136 tonnes of gold, worth around $70 billion.

China continued its gold-buying spree with 62 tonnes added in the months of November and December, amid rising geopolitical tensions with the United States. Overall, emerging markets continued the trend that started in the 2000s, accounting for the bulk of gold purchases. Meanwhile, a significant two-thirds, or 741 tonnes of official gold purchases were unreported in 2022. According to analysts, unreported gold purchases are likely to have come from countries like China and Russia, who are looking to de-dollarize global trade to circumvent Western sanctions.
