What Makes Gold Special?December 27,2021
The magnificence, unique qualities, and overall value, makes it the first choice of material for many different industries. Out of the total gold produced every year – nearly 78% - is used for the purpose of jewellery making. Other 10-12% goes towards usage in other industries like electronics, medical, dentistry. And the remaining gold supply for the year goes towards use in the financial industry for transactions.
All these diverse symbolisms and uses gives rise to one important question – What makes such a special metal? Well, the simple answer to this is the properties of this glowing metal. Want to know find out these attributes? Then keep reading…
Out of all the metals present in the periodic table, gold is by far considered the noblest. This is because gold is in fact the least chemically reactive metal (under normal circumstances). So, when gold interacts with another atoms or molecules be it gaseous or liquid, it does not tend to react. As a result of this it proves to be relatively a stable metal and thus appropriate for use within different industries.
It is a well-known fact that gold is a good conductor of both heat and electricity. This is due to the chemical structure of gold as well as its other properties. Its natural malleability and ductility result it being considered the best heat conductor. Also, gold has a very high resistance to corrosion which further adds to its ability of being a good conductor for electricity as well.
Tarnishing refers to the colour changing or fading process that a metal goes through upon getting wet or worn/used every day. But, in case of pure gold, this does not occur as gold is relatively an unreactive metal. So as many times it gets wet or worn, there is the least possibility that it will react. Hence, it is considered tarnish-free, and a great choice for making electrical components.
But in case of gold of varying purity that is used in making jewellery, there is a chance of it getting tarnished. Reason being that the other metals like silver, zinc that are alloyed with gold, do react to the environment. Hence, the tarnishing.
Another characteristics that contributes to gold’s uniqueness is – its ductile nature. As gold is one of those metals that can be stretched into very thin wires without breaking. It can be turned into the thinnest of wires and gold won’t become weak or brittle during the process. therefore, many wires are made of gold and even copper wires are covered with gold plating to avoid them reacting or tarnishing.
Malleability in simpler words is the flexibility of a metal. Gold is one of the most malleable metals available. It has the capability of being stretched and bend into various shapes and beaten into thing, long sheets. For example, a single ounce of gold can beaten into a 5 meters wide sheet roughly. This thin sheet is generally known as gold leaf and used for arts and craft.
A contradictory point of gold is that despite being soft and malleable, it is actually a heavy metal. Unlike other heavy metals, gold isn’t brittle and does not break easily. This is because, as per its structure, each individual atoms of gold are heavy. Hence, it is said to be a dense material in nature. In fact, gold even ranks within the top 5 dense metals available.
Gold does not absorb light or heat resulting in it being supremely reflective of both. No amount of heat or rays of light are absorbed by gold, all are simply just reflected. Due to this, it is used to manufacture products used in space. Usually, a very thin gold film is applied which is able to reduce the glare, light and heat from the sunlight in space, ensuring better visibility.
An undeniable truth about gold is that this metal is simply beautiful. With its glowing golden-yellow hue and its value, this metal is certainly a winner. But that’s not only what makes this metal precious. Its ability to be beaten, bent, hammered, stretched, twisted without breaking adds to its desirability as well.
Well, are you convinced or need we say anymore? A metal with so many positive attributes can definitely be nothing short of one-of-its-kind. After reading this, there isn’t any doubt that gold is cherished and a prized possession to everyone who owns it. Plus, all these abilities of gold, just highlight its distinctiveness and give more reasons to add it to your wardrobe. So, what’s the wait for?
