Many people buy and sell precious metals because they are viewed as investments that may retain value during economic uncertainty. Yet most precious metals also have distinctive properties that give them practical uses beyond investing. Everyday items may contain precious metals without the user realizing it. This article outlines three industrial uses for gold, silver, and platinum.
Platinum Controls Vehicle Emissions
For decades, automakers have used platinum in vehicles to reduce carbon monoxide emissions and other gaseous pollutants. In a vehicle’s catalytic converter, platinum’s chemical qualities help break down harmful gases. Studies have indicated that platinum may lower toxic gases and particles in exhaust by as much as 90%. Platinum also appears in fuel cells for vehicles powered by hydrogen rather than gasoline. Palladium can perform many of platinum’s functions, although, at the time this article was written, it was the more costly alternative.
Gold Beyond Earth
While gold coins and bullion are highly valued on Earth, gold also plays a part in producing equipment launched into space. Because it conducts electricity efficiently and resists corrosion, gold is well suited to the circuitry used in spacecraft and space rovers. NASA has also explained that gold’s strong conductivity can help protect astronauts and satellites from the severe heat and radiation present in space.
Medical Applications for Silver
Silver appears in remote controls, cameras, dental drills, and many other products, but a particularly important application is medical care. This precious metal can destroy bacteria, fungi, and even viruses. Scalpels, needles, and stethoscopes are frequently lined with silver to help resist harmful microorganisms. Silver is also incorporated into bandages and wound dressings to aid in preventing infections.
The industrial roles of precious metals are interesting, especially as the original article described seemingly new uses every day, but its focus was their investment value. At the time of publication, Atlanta Gold & Coin Buyers stated it offered competitive rates for buying or selling gold, silver, platinum, and other precious metals. It said its experts could accurately appraise coins or bullion in a collection. The article also stated a commitment to honesty and transparency, including posting its buying rates online. When originally published, Atlanta-area readers were invited to arrange an appointment by calling (404) 236-9744.
