How Do I Know If My Tungsten Ring Has Cobalt?

The only way is to contact the retailer which sold you the ring and ask them if the ring contains cobalt. Ideally, the ring should be labeled with what it has been alloyed with – and many cobalt free tungsten rings are labeled as ‘cobalt free.

Does tungsten contain cobalt?

Rings crafted from tungsten can contain either cobalt or nickel binders. While nickel may be an irritant, tungsten and nickel alloys are actually hypoallergenic.

What is the difference between cobalt and tungsten rings?

While cobalt is harder than titanium, and therefore more scratch resistant, tungsten is still the hardest metal currently on the market. In simple terms, although cobalt and tungsten are both extremely hard metals, a tungsten ring will have a higher resistance to scratching.

Can you get cobalt poisoning from a ring?

The ONLY toxic metal you may hear of is pure cobalt. HOWEVER, pure cobalt is NEVER used for jewelry. Every “cobalt ring” you find will be made of a cobalt alloy. These metals are nontoxic.

Does tungsten carbide have cobalt?

In addition, tungsten rings containing cobalt could cause allergic reactions to the skin, leaving you not only with a green finger, but green with envy at those who chose a tungsten carbide ring that did not contain cobalt. At Tungsten & Co, you can rest assured that our tungsten carbide rings do not contain cobalt.

Why is my tungsten ring giving me a rash?

When your skin comes into contact with the metal of the ring, your body releases chemicals that cause the area to itch and become irritated. Occlusion dermatitis is often the result of a buildup of soap, moisture, or debris underneath a ring.

Can I be allergic to my tungsten ring?

* Contact can cause severe skin burns. * Tungsten Carbide may cause a skin allergy. If allergy develops, very low future exposure can cause itching and a skin rash. * Exposure to Tungsten Carbide combined with Cobalt or Nickel can cause a lung allergy with wheezing, coughing and shortness of breath.

Is cobalt more expensive than tungsten?

As far as price, cobalt wedding rings are just a touch more expensive than titanium and tungsten weddings bands. As cobalt becomes more popular though, the price for these wedding rings will most likely become on par with titanium and tungsten.

How do you test a tungsten ring?

Test the Ring Out
A top quality tungsten carbide ring will never lose its shine. Check your ring by trying to smudge and mark it; if it resists, then it is a good one. If it smudges easily and loses its shine within minutes, you know you have a poor quality product on your finger.

Will cobalt rings turn finger green?

Will Cobalt Rings Turn Your Finger Green? Since cobalt chrome is 100% hypoallergenic, it will also not oxidize or tarnish over time. This means you will never have to worry about cobalt rings turning your finger green or ever rusting.

What are the signs of cobalt poisoning?

Cobalt poisoning can occur when you are exposed to large amounts of it.
Symptoms

• Cardiomyopathy (a problem where your heart becomes big and floppy and has problems pumping blood)
• Deafness.
• Nerve problems.
• Ringing in the ears (tinnitus)
• Thickening of the blood.
• Thyroid problems.
• Vision problems.

What are the symptoms of a cobalt allergy?

A cobalt allergy typically begins when you’re exposed to cobalt in eye makeup, tattoos, or industrial products. It causes an itchy, red, scaly rash. A vitamin B12 sensitivity can appear as a rash after you take a supplement.

How do you test for cobalt?

1,2 Laboratory testing is needed to detect high levels of cobalt in the body that may lead to cobalt toxicity. Inductively coupled plasma/mass spectrometry (ICP/MS): An argon plasma at 6,000-10,000 K destroys the organic matter in the sample and ionizes the metals.

Can you be allergic to cobalt rings?

Cobalt is one of the most common metals to cause contact allergy via a delayed hypersensitivity reaction.

Will a magnet pick up tungsten carbide?

Is tungsten magnetic? Tungsten, by itself, has a very low susceptibility to magnetism. However, tungsten carbide, which is an alloy of tungsten and carbon, is, in essence, magnetic because the elements in it are susceptible to magnetism.

What is tungsten cobalt?

Tungsten carbide-cobalt (WC-CO) is an alloy of a hard ceramic phase, the tungsten carbide (WC) and a ductile metallic phase, the cobalt (Co). Important properties of tungsten carbide-cobalt are hardness, strength, high breaking and beating ductility as well as high electrical and thermal conductivity.

How do you tell if your tungsten is contaminated?

Tungsten electrode contamination is another common pitfall that can occur during TIG welding. Indications that tungsten electrode contamination has occurred are: one, the weld puddle appears dirty; two, the filler rod does not join or melt smoothly into the weld puddle; and three, the arc becomes erratic.

Can you get heavy metal poisoning from tungsten?

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).

Why am I suddenly reacting to my wedding ring?

A reaction to a particular piece of jewelry may occur suddenly because nickel salts tend to come to the surface years later, or after protective coating has worn away. “You get more exposure to nickel the older the piece of jewelry is,” says Jeffrey Benabio, a dermatologist with Kaiser Permanente in San Diego.

What is tungsten poisoning?

Chronic tungsten poisoning
Tungsten may be implicated in cases of pulmonary fibrosis due to hard-metal lung disease. This giant cell interstitial pneumonitis is contracted from inhaling the dust formed from the manufacture, utilisation or maintenance of hard metal, a material composed of tungsten carbide and cobalt.

Are tungsten rings toxic?

Tungsten rings are indeed safe to wear. Just like lima beans, tungsten isn’t intended for use in its raw state. However, after it has been processed, jewelry grade tungsten is perfectly safe for that finger.
