Element of Tungsten
the toughest things found in nature
Tungsten is known as one of the toughest things found in nature. It is super dense and almost impossible to melt.
Tungsten familiar to many people as the metal used in incandescent light bulb filaments. Its element symbol W derives from an old name for the element, wolfram. Here are some interesting facts about tungsten and how we use tungsten as our core material.

Tungsten
Tungsten is an extremely rare element with just 100 parts per billion contained within the Earth’s crust. It has the highest melting point of any metal at 3,422° C (6,170° F) and as such, it is an incredibly difficult metal to process and work with.
However its ability to withstand high levels of compression and heat have made it an ideal alloy for rocket engine nozzles, radiation shielding and aerospace tooling.

Tungsten Kilogram Prototype Fun Facts
Why Tungsten?
What makes tungsten unique?
Tungsten has the highest melting point of any metal. Its ability to withstand high levels of compression and heat have made it an ideal alloy for rocket engine nozzles, radiation shielding and aerospace tooling.
How does it actually feel to hold the kilogram prototype?
You will most likely never encounter anything this size that weighs this much.
It’s the ultimate conversation starter, people will be blown away by how heavy it is.
What grade of Tungsten is using for the DeskTech Kilogram prototype?
The DeskTech Kilogram Prototype made of Class 3 Tungsten Alloy. It has high tensile strength from 700 – 1000 MPa with high density of 17.75-18.35/cm3.
Is Tungsten stronger than diamond?
Is Tungsten harmful to touch?
Tungsten is considered to have low toxicity and plays a biological role in organisms. This makes it the heaviest element used in biochemical reactions. In animals, tungsten interferes with copper and molybdenum metabolism, so it is considered slightly toxic.
What is tungsten used for in daily life?
Tungsten is used in filaments in incandescent light bulbs, it is also used in electric contacts and arc-welding electrodes.
Tungsten gives bold and beautiful feeling, which some people use them as wedding ring as well!
Is the Kilogram Prototype layered/coated?
Yes, The Tungsten cylinders are chemically cleaned and sent for electroless nickel plating, providing a high-quality corrosion-resistant layer in order to create the best look of the kilogram prototype.
