What Are the Properties of Gold? 

Gold is a naturally occurring mineral and is considered one of the most valuable elements in the world. As of September 2024, a single ounce of gold is worth nearly $2,500. Gold’s exceptional shine, malleability, and ductility make it an ideal investment vehicle, and consumers use gold coins, bars, and jewelry to diversify their investment portfolios. 

To understand why gold is such an important mineral, investors should understand at least the basic properties of gold. On this page, we’re covering the properties of gold, as well as the mineral’s physical qualities and most popular uses. 

Gold – Basic Physical Qualities 

What are the physical properties of gold? Here are the basic properties of gold: 

• Atomic Number: 79
• Atomic Weight: 196.96657
• Melting Point: 1,063 degrees Celsius (1,945 degrees Fahrenheit)
• Density: 19.3 grams per centimeter cubed

These physical properties help scientists differentiate between gold and similar metals. Gold’s most important qualities, including its malleability, conductivity, and more, are the reasons why the precious metal has been considered valuable for thousands of years. 

Most Important Properties of Gold

Gold is a unique element. The precious metal has a reasonably low melting point and is also highly malleable, ductile, and conductive. Together, these qualities help make gold an essential manufacturing component in dozens of industries. 

Malleability and Ductility of Gold

How malleable is gold? Gold is the most malleable metal on the planet. Malleability refers to how easily a metal can be shaped. As you probably already know, malleability is an important quality for any metal made into bars or coins. If a precious metal isn’t malleable, then it is difficult to form it into the fine, detailed shapes we find on many modern bullion coins. 

Gold’s ductility is another quality that helps make it perfect for coinage. Is gold ductile? Gold is extremely ductile, which means that it can be stretched or deformed quite a bit before breaking. Obviously, coins that are repeatedly beaten and stretched during the minting process must be made out of a material that won’t crack or break. 

The high malleability and ductility of gold are two properties that make investment-grade gold bullion possible. If gold wasn’t malleable, we wouldn’t be able to shape it into precious metal coins. And if the precious metal was not ductile, then coins and bars would likely break during the minting process. 

Gold’s Melting Point 

Ever wonder why stainless steel or titanium coins aren’t very popular? One reason why gold is a popular choice for bullion coinage is the precious metal’s relatively low melting point. In order to form a precious metal into a coin, bar, or round, mints need to turn it into a liquid. A higher melting point means that it takes a higher temperature to convert a metal into liquid, which complicates the minting process. 

What is gold’s melting point? Gold’s melting point is 1,063 degrees Celsius, or 1,945 degrees Fahrenheit. By comparison, platinum doesn’t melt until it hits a temperature of around 1,770 degrees Celsius, and titanium only melts at 1,670 degrees Celsius. 

If gold were much harder to melt, we might see far fewer mints offer gold coins and bars. Gold’s malleability and ductility make it easy to shape into beautiful bullion products, but its melting point makes it possible to shape in the first place!

Conductivity of Gold 

Gold’s conductivity doesn’t play a role in the minting process of gold coins or bars, but it does help give gold a wide range of industrial uses and demand drivers. Gold is one of the most conductive metals. In fact, gold conducts electricity better than copper, aluminum, and silver! 

Here’s a fun fact: gold is used in many modern electronics! As we’ll cover later on this page, electronics account for around 5% of global demand for gold, which turns out to be quite a bit of the precious metal annually. Some phones use gold, and most computers contain trace amounts of pure gold. 

The high conductivity of gold is one of the biggest reasons why the precious metal is so expensive. In addition to being beautiful and valuable as an investment, gold is useful. 

More About Gold’s Properties

Since its first discovery thousands of years ago, gold has been a constant fascination for humanity. But what makes gold so rare and valuable? Gold’s value comes from a combination of its rarity and usefulness. Because the precious metal is both difficult to find and useful to have, it has always been considered a valuable investment – and a sign of wealth and class. 

Let’s take a look at some of gold’s other properties that help make it such a popular investment vehicle. 

Abundance of Gold – How Rare is Gold?

Everybody knows that gold is valued primarily because of its rarity. Just how rare is gold? Gold is found in the Earth’s crust at a rate of .004 parts per million, making it one of the rarest minerals on the planet. Gold is rarer than platinum and silver but is more common than rhodium, which is widely considered the rarest of all precious metals. 

Some metals are technically rarer than gold but are less valuable, since the value of a commodity is usually a function of both supply and demand. Gold maintains a high value because it is both rare and always in demand. Precious metals that are rare but not very useful are naturally less valuable than gold, which is both very rare and extremely useful. 

Where is Gold Found?

Where is gold found? Gold can be found nearly anywhere in the world. Most modern gold deposits are situated near river banks, as erosion over thousands – or millions – of years can reveal ancient pockets of gold that were once hidden inside the Earth’s crust. 

Large gold nuggets have been found on almost every continent, both by accident and by professional miners. The vast majority of gold produced annually comes from industrialized mining operations run by nearly every country on the planet.

Most countries mine at least some gold each year for the massive gold bullion market. China, Australia, and Russia are the three largest producers of gold on the planet. Which countries produce the most gold? The top gold producers as of 2022 are: 

1. China – 330 metric tons
2. Australia – 320 metric tons
3. Russia – 320 metric tons
4. Canada – 220 metric tons
5. United States – 170 metric tons
6. Mexico – 120 metric tons
7. Kazakhstan – 120 metric tons
8. South Africa – 110 metric tons
9. Peru – 100 metric tons
10. Uzbekistan – 100 metric tons

In total, the countries of the world produce around 3,100 metric tons of gold per year. That’s enough gold to make 99,667,170 one ounce gold coins! Of course, most of the gold produced annually by countries like China, Australia, Russia, and Canada doesn’t actually end up in gold coins. 

What is Gold Used For? 

Surprisingly, gold bars and coins are not the biggest demand drivers for gold. Gold’s biggest use is actually in gold jewelry, which makes up 46% of annual demand for gold bullion. Investment by central banks is the second biggest use for gold, followed by gold bars, gold coins and medals, and electronics. 

What is gold used for? Gold’s most common uses can be broken down into five main categories: 

• Jewelry – 46%
• Banking Uses – 23%
• Gold Bars – 16%
• Coins and Medals – 9%
• Electronics/Electrical – 5%

Final Thoughts: Properties of Gold

For thousands of years, humans have innately understood the value – and power – of gold. Men have fought wars over golden riches, religions have sanctified their beliefs with gold artifacts, and investors have used gold to safeguard their wealth for centuries. 

But gold’s dominance of humanity’s imagination is no accident. The metal’s unique properties make it perfect for all of the uses that gold has come to be known for. Offering a reasonably low melting point, high ductility and malleability, and, most important, extremely low abundance, gold is chemically perfect for an investment unlike any other.
