What can cut through tungsten?
While other metals can be removed with a wedding ring cutter, tungsten rings are a type of ring that can only be "cut" with vice grips or any kind of locking pliers. Most emergency personnel have this common tool, as well as your local emergency rooms.
Tungsten carbide is famous for its wear resistance; in fact, it can only be cut using diamond tools.
Well, it is the very attribute that keeps Tungsten Carbide looking new, that also makes it likely to break if you drop it from a height of several meters onto concrete. Or hit it hard with a hammer. It does not however, spontaneously shatter or implode when you drop it under normal every day circumstances.
Background: The removal of metal rings from fingers is a well-described process that often employs a toothed cutting wheel or bolt cutters to sever the ring and allow it to be pried open. However, tungsten carbide (TC) rings are impervious to these traditional ring-cutting devices.
Tungsten's very high melting point is also its weakness: It makes it very hard to work: Melting & casting is practically impossible, sawing, machining & forming very difficult.
It has an atomic number of 74 and a relative atomic mass of 183.84. Tungsten is a solid at room temperatures because of a stable isometric crystal formation which can be seen under an x-ray. Tungsten is very resistant to corrosion by acids and is only vulnerable to nitric acid and hydrofluoric acid.
In fact, the harder the metal, the more brittle and breakable it is (unlike gold, which is soft and malleable, meaning it will bend rather than break). If you drop a tungsten ring, or if you accidentally smash it against a hard surface, the metal may crack or shatter.
Break car window easily: the bracelet is made of an tungsten carbide bead, which has excellent strength and hardness. Just a single strike directed from this device can instantly destroy tempered glass.
That is the reason why even though a hardened steel file cannot scratch a tungsten ring, some nail files can due to the fact that the nail files are made from diamond encrusted sandpapers.
Many common metals such as aluminum, copper, brass, gold, silver, titanium, tungsten, and lead are not ferromagnetic. They cannot be made into magnets and will not be attracted to magnetic fields.
How do you break down tungsten?
While unscratchable, tungsten rings are very brittle and not malleable. Gently apply firm compression using an adjustable vise grip (borrow from your hospital's electrical or engineering department). This will fracture the ring.
It is slightly soluble in hydrochloric and sulphuric acids, giving purple solutions.
A regular wire cutter or hacksaw will not even be able to put a dent on the ring. However, a rotary saw with a diamond coated blade can cut through a tungsten carbide ring in seconds.
And its density and hardness is why the military has called tungsten into service in another kind of evolutionary arms race. "Tungsten makes very good bullets," the military analyst Robert Kelley tells me. "It is the kind of thing that if you fire it at someone else's armour, it will go right through it and kill it."
Materials that can be processed by laser cutting include alloys, steels, copper, aluminium, tungsten, titanium, diamond, alumina, zirconia, green ceramics, PZT, silicon nitride, tungsten carbide, polyimide, polyethylene, PMMA, Kapton, Vespel, Cirlex, ABS, sapphire, quartz, and glass.
Tungsten is a relatively inactive metal. It does not combine with oxygen at room temperatures. It does corrode (rust) at temperatures above 400°C (700°F. It does not react very readily with acids, although it does dissolve in nitric acid or aqua regia.
Chemical properties
At around 250 °C it will react with chlorine or bromine, and under certain hot conditions will react with iodine. Finely divided tungsten is pyrophoric. Tungsten carbides (W2C and WC) are produced by heating powdered tungsten with carbon.
We conclude that the optimal heat generated by lava at 2,190°F cannot melt the tungsten because of its high melting point. Other examples of metals and ceramics that can withstand lava's temperature include; titanium, iridium, iron alloys, osmium, nickel alloys, aluminum oxide, mullite, and silicon nitride.
Titanium – This naturally occurring metal has the highest tensile strength to density ratio of any metal, which makes it, pound-for-pound, stronger than tungsten.
Tungsten's hardness is what makes it so resistant to scratching. That same level of hardness also means that it won't bend, but it will break or crack if enough force is applied to it, similar a diamond.
Is tungsten the hardest metal?
Furthermore, it has the highest tensile strength at 1650°C. Apart from this, it has an atomic number 74 in the periodic table. The melting point at 3410°C and boiling point at 5530°C. As a result, the Tungsten is one of the hardest metal present on earth.
Tungsten rings can shatter when enough force is applied to them. Tungsten is the hardest metal on earth. This means that instead of bending like a gold ring, tungsten has to break. Tungsten rings are made from the most scratch resistant metal on the planet.
Tungsten carbide is a brittle metal, which means that you can actually “shatter” it into large pieces using the right pressure.
If what you have is a genuine and high-quality tungsten ring, then it is most definitely waterproof. Tungsten is not soluble in water, and water cannot penetrate the surface of a tungsten ring. Tungsten carbide, which is an alloy of tungsten and carbon, is extremely inert and will not react with humidity or air.
Tungsten rings are not very brittle. If you drop a tungsten ring from a 100 ft, 99% of the time nothing will happen to it. The pressure it takes to crack or shatter a tungsten ring would be about equivalent to inserting a ring in vice grips and squeezing as hard as you could.
Tungsten vs Titanium
As mentioned above, tungsten is the strongest of any natural metal (142,000 psi). But in terms of impact strength, tungsten is weak — it's a brittle metal known to shatter on impact. On the other hand, Titanium has a tensile strength of 63,000 psi.
It was recently discovered that significant erosion/corrosion occurs with machinable tungsten when exposed to water, particularly when the water has dissolved oxygen present.
Durable - Tungsten is about ten times harder than gold, and it rates at a nine on the Mohs scale of hardness. A diamond is a ten on the Mohs scale of hardness. This rating means that the metal is far more scratch-resistant than gold and other metals.
No specific health effects have been associated with exposure to tungsten in humans. Exposure to high levels of tungsten is unlikely. Tungsten has been found in at least 6 of the 1,662 National Priority List sites identified by the Environmental Protection Agency (EPA).
Yet the pressing reason for recycling tungsten, especially for someone with abundant scrap on hand, is its financial worth. Measured against other common scrap metals, steel, and aluminum among them, tungsten scrap price per pound will typically exceed that of other recyclable metals.
How much does tungsten sell for?
Form of Tungsten
This is a function of the raw material cost and of the amount of work involved in producing the finished product. A broad range of prices for finished tungsten products would be from $25 to $2500 per kilo, with the majority of products in the $100 to $350 per kilo range.
With all of the “salesy” information out there about the benefits of having a tungsten wedding ring, you could be forgiven for thinking that they're near invincible. As much as we'd like to tell you that they are, it's simply not true.
Tungsten bands do not react to sunlight, salt water or anything that your body emits.
Tungsten does not rust or tarnish, but chlorine bleach, and ammonia will damage the surface of the ring. This is why you should take off your tungsten wedding band if you want to swim in a pool.
The electrical conductivity of these tungsten electrodes is extremely high compared to other types. If the starting current is set too high, the tip of the tungsten electrode will split immediately at the start.
Historically, tungsten was thought to be insoluble and have little or no mobility in the environment. However, the presence of tungsten in groundwater near background sources and anthropogenic sources suggests that under certain conditions, tungsten dissolves in water and is mobile in the environment.
Tungsten is a poor conductor of electricity even though it is a metal. But at high temperatures, it will conduct electricity. As discussed above, it has a high melting point. Therefore, high temperature doesn't have any bad effect on Tungsten.
Important Information regarding cleaning your tungsten:
Do not, by any means, using any harsh cleaning materials/chemicals such as ammonia, bleach or chlorine. These chemicals can damage your tungsten ring. It would be wise to avoid any chlorine treated pools or Jacuzzis when using your ring.
The answer is yes. Tungsten rings can be removed in an emergency, and most hospitals and medical facilities have the tools that can cut and crack tungsten jewellery. By cracking the ring and weakening its tensile strength, the tungsten ring can easily be removed from your finger and relieve the pressure.
Tungsten Carbide Folding Knives
When you carry a pocket knife you expect it to be sharp and ready to cut when you need it. The first generation of Tungsten Carbide Folding Knives, the TCK and TCK 416, proved that our blades cut better and stay sharp at least 4x longer than the highest quality steel knives.
Can you forge a knife out of tungsten?
Tungsten carbide is an ideal material to forge blades out of because thanks to its hardness and other properties, a much finer yet more durable edge can be fashioned once the blade has been formed. Carbide blades need far less sharpening than those made of stainless steel or titanium.
Secondly, the tungsten carbide was wrapped outside the Hiroshima bomb to give it strength and hold it together for a brief period longer prior to detonation; it was not used for any purpose other than for being a tamper.
Uranium metal's high density provides the penetrator with momentum and a straight trajectory, something almost impossible to stop. Tungsten, which has a similar density to uranium, can also be used but DU has greater target penetration.
In the end, titanium is bulletproof for the most part against bullets fired from guns that one would likely find on the shooting range, on the street or on the hunt in the mountains. Most guns legally bought and owned by individuals will likely not penetrate titanium.
For instance, plasma cutters cannot cut wood, glass, and plastics, or poorly conductive metals like manganese, lead, tungsten, and tin.
For example, diamonds are the hardest material on Earth, even harder than tungsten carbide. The only substance on Earth that can scratch a diamond is another diamond. However, if you take your trusted hammer and strike a diamond, it will easily chip or crack. It is not indestructible and neither is Tungsten carbide.
Tensile strength, of course, refers to a material's ability to withstand force or pressure without breaking. Tungsten has a tensile strength of about 50,000 to 60,000 pounds per square inches (PSI), which is more than any other material. Unless it's exposed to 60,000 PSI or more, it shouldn't break.
While unscratchable, tungsten rings are very brittle and not malleable. Gently apply firm compression using an adjustable vise grip (borrow from your hospital's electrical or engineering department). This will fracture the ring.
And its density and hardness is why the military has called tungsten into service in another kind of evolutionary arms race. "Tungsten makes very good bullets," the military analyst Robert Kelley tells me. "It is the kind of thing that if you fire it at someone else's armour, it will go right through it and kill it."

Does tungsten break easily?
It's important to note though that even tungsten isn't completely indestructible. It is very hard and brittle, so if it's slammed against a very hard surface or smashed with a hammer (PSA: don't do this), it's possible for a tungsten ring to shatter.
