History will give testimonial evidence to the fact that metals have always been a desirable commodity. From ordinary people to kings and queens, it has managed to leave its footprints on the sands of time. Each metal has a different value as per the conditions of that period.
There was a time when iron was more valuable than anything else, later silver and much later, gold took its place and now several other precious metals have replaced it.
The value is dependent to a great extent on the rarity of the metal, its properties, and how difficult it is to extract. They have been used as currencies, as forms of investment, for industrial purposes and also to create jewelry.
The one thing common amongst all the metals is that they are no doubt valuable. The prices may go up and down, but it will always remain precious in the consumer market.

The metal is a favorite of electronic and chemical industries. In order to improve temperature, strength Rhenium is added to nickel-based superalloys.
It is extensively used in turbine engines and in manufacturing thermocouples, electrical contact materials, and filaments.
Gold is the only metal that retains good value even during political, economic, and financial instability. Investment in gold is always considered safe, and this is why it is one of the most sought-after and most expensive metals of all times. Gold is also used in making jewelry.
Its reflective surface makes great office windows and radiation shields, whereas its conductivity has electronic usage, and it is also used for thermal insulation. The precious metal is found in several countries, but the largest producers are Russia, Australia, United States, China, and South Africa.
At 1,285 dollars per ounce, gold is one of the most expensive metals in the world. The yellowish-golden metal is highly desirable because it does not loses its luster, is malleable and durable. Gold is surrounded by minerals and rocks. You need gold-mining equipment to separate it.
Later after undergoing several stages like smelting, chemical reaction, and gold-refining process,, the most expensive metal is derived in its purest form.
There was a time when platinum was considered more valuable than gold, but in recent years it has become vice-versa. At a price tag of 894 dollars per ounce, it is no doubt one of the most expensive metals but not more than the precious gold.
Platinum is available in few countries, and the largest producers are Canada, Zimbabwe, China, United States, Russia, and South Africa.
Platinum is a versatile metal that has wide and extensive usage. It is one of the heaviest metals with high malleability. It is also known for its non-corrosive properties, density and its ability to withstand large quantities of hydrogen.
Its lustrous look and silvery-white hue is an advantage in making jewelry as it gives a very good finishing. Platinum is also used in aeronautics, weaponry, and dentistry.
