4 Platinum Uses for Investors to Know
Platinum uses are incredibly varied — the metal can be used in autocatalysts and jewelry, as well as for medical and industrial purposes.
Platinum may be rare, but it is the third most-traded precious metal in the world, behind gold and silver.
The world’s platinum demand varies widely across many sectors. Most notably, platinum metal is used in autocatalysts and jewelry, as well as for medical and industrial purposes. Those interested in investing in platinum would do well to be aware of the many platinum uses. After all, by knowing which industries require platinum, it’s possible to understand supply and demand dynamics, and to be aware of how the precious metal’s price may move in the future.
With that in mind, here’s a list of the four main platinum uses. Scroll on to learn more about them, and click here to see a breakdown of platinum’s key applications in infographic form.
1. Platinum uses: Autocatalysts
One of the main platinum uses is in the construction of autocatalysts. An autocatalyst is a “cylinder of circular or elliptical cross section made from ceramic or metal formed into a fine honeycomb and coated with a solution of chemicals and platinum group metals.” An autocatalyst mounted inside a stainless steel canister is known as a catalytic converter.
Catalytic converters are installed in a vehicle’s exhaust lines, between the engine and muffler, where they are used to moderate the dangerous qualities of exhaust. Specifically, the autocatalysts that vehicles contain convert over 90 percent of hydrocarbons and carbon monoxide into carbon dioxide, nitrogen and water vapor. They can also convert pollutants from diesel exhaust into carbon dioxide and water vapor, which is immensely helpful in reducing pollution.
Autocatalysts have been used in the US and Japan since 1974, and are now so common that over 95 percent of new vehicles sold each year have one. As a result, they are a significant source of platinum demand that is not likely to disappear in the future. Indeed, as pollution rules become more stringent, car companies are looking at creating even more efficient autocatalysts.
2. Platinum uses: Jewelry
Platinum has many qualities that make it ideal for use in jewelry, and that is the second largest source of platinum demand. The metal is strong, resists tarnish and can repeatedly be heated and cooled without hardening or oxidizing.
When used to make jewelry, platinum is commonly alloyed with other platinum-group metals such as palladium, as well as copper and cobalt, so that it is easier to work with.
The history of platinum jewelry is long. More than 2,000 years ago, Indigenous people in South America made rings and ornaments out of platinum. Egyptians used platinum for decoration as early as the 7th century BCE. Meanwhile, Europeans began to use the metal in jewelry in the 18th century and continue to do so to this day. Currently, China is the largest market for platinum jewelry.
3. Platinum uses: Industrial
Platinum’s industrial applications could fill a book all on their own. For instance, platinum catalysts are used to manufacture fertilizer ingredients, and the metal is a key component in silicones, hard disks, electronics, dental restoration, glass-manufacturing equipment and sensors in home safety devices.
Another platinum use is in the construction of hard drives with extremely high storage densities. And, because it is reactive to oxygen, oxides of nitrogen and carbon monoxide, platinum can be used to detect changes in the amount of those materials in vehicles and buildings. For the same reason, platinum is also used in medical sensors, particularly medical instruments that measure blood gases, to detect oxygen.
4. Platinum uses: Medical
Platinum is used in electronic medical devices like those mentioned above, as well as in catheters, stents and neuromodulation devices. It is ideal for these applications because of its durability, conductivity and biocompatibility. The metal is also inert within the body, making it safe for implantation.
To meet other medical needs, platinum can be formed into rods, wires, ribbons, sheets and micromachined parts. Further, it helps fight cancer in the drugs cisplatin and carboplatin, which are widely used to treat testicular cancer, as well as ovarian, breast and lung cancer tumors.
FAQs about platinum
How much is platinum worth?
In 2022 and moving into 2023, the price of platinum is holding around the US$1,000 per ounce mark. Although the industry is facing a growing supply deficit, it is also dealing with lagging demand.
The shortfall in supply is related to COVID-19 lockdowns seen in 2020 and 2021, and more recently Russia's war in Ukraine. Russia typically ranks as the world’s second largest platinum-producing country. Meanwhile, the semiconductor shortage and inflationary pressures worldwide are curbing demand for platinum from the automotive industry.
Which is more valuable, gold or platinum? Why?
Platinum is 30 times rarer than gold, much harder to mine and in high demand due to its important industrial uses. Precious metal gold has long been valued as a form of currency and a store of wealth, yet platinum jewelry often has a higher price point than gold jewelry. Platinum in general has historically traded on par or at a premium to gold, but since 2015 the two metals have diverged in price, with the gold taking the high road. This split has been attributed to gold’s safe-haven status and platinum’s reliance on the industrial and jewelry markets, which don’t fare well in times of economic uncertainty.
What’s the best investment, gold or platinum?
Both gold and platinum have wealth-generating potential, but it's important to determine which precious metals fit your investment strategy; consider looking at supply, demand and prices for each option before making a decision.
