Tungsten carbide can safely be used in the food industry and offers many advantages. Wear-resistant solutions by DURIT are characterized by HIGH CORROSION RESISTANCE. This makes cleaning of machine parts with aggressive solvents possible – just as with stainless steel.
* Exposure to Tungsten Carbide combined with Cobalt or Nickel can cause a lung allergy with wheezing, coughing and shortness of breath. Repeated exposure may cause scarring of the lungs (pulmonary fibrosis). * Exposure to cemented Tungsten Carbide may result in exposure to Nickel or Cobalt.
Tungsten is a naturally occurring element. Exposure to very low levels of tungsten may occur by breathing air, eating food, or drinking water that contains tungsten. No specific health effects have been associated with exposure to tungsten in humans. Exposure to high levels of tungsten is unlikely.
The Thorium used in 2% thoriated tungsten is a radioactive element and therefore can be dangerous to the health of those exposed to it and to the environment.
❖ Occupational exposure to tungsten is known to affect the eyes, skin, respiratory system and blood. Tungsten may cause irritation to eyes and skin; diffuse interstitial pulmonary fibrosis; loss of appetite; nausea; cough; and changes in the blood (Gbaruko and Igwe 2007; NIOSH 2010).
Tungsten is a transition metal in the same block as many of the carcinogenic metals on the periodic table and holds potential to induce cancer-associated effects.
The studies of production workers indicated an increased risk of lung cancer. The increased risk was restricted to workers with elevated dust exposure and, in the most informative study from Norway, was linked to estimated cristobalite exposure, a form of crystalline silica.
Tungsten heavy alloy cube is completely non-toxic and environmentally friendly so tungsten heavy alloy cube is often used in weighting applications,especially used in pine wood derby cube to offer a pinewood derby kits.
There is no evidence that you can get tungsten poisoning from wearing a tungsten ring. However, if you are allergic to metals like nickel and cobalt, wearing a tungsten ring that contains these additional metals may trigger allergic symptoms.
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.
Tungsten carbide, which is an alloy of tungsten and carbon, is extremely inert and will not react with humidity or air. The result is a great waterproof material that is perfect for wedding bands. So if you are wondering if you can wash your hands while wearing a tungsten wedding ring, the answer is yes.
While nickel may be an irritant, tungsten and nickel alloys are actually hypoallergenic. This is because in the process of combining both metals, the nickel binds so well with tungsten that it loses its ability to react with the skin.
As an element, tungsten can be neither created nor destroyed chemically, although tungsten can change forms in the environment.
All tungsten compounds should be regarded as highly toxic. The metal dust presents a fire and explosion hazard.
Cheap tungsten rings are cheap due to less time spent on labor. This translate to rings that are not made with as much precision or care, which ultimately translates to lower quality. Every one of Timeless Tungsten's rings are manufactured with dedicated craftsmanship and precision labor.
Tungsten Isn't Always A Better Choice Than Titanium
Of the two metals, tungsten is the strongest and it's more scratch-resistant. Tungsten carbide is 8.5 to 9 on the hardness scale, while titanium is 6. Tungsten can only be scratched by a metal or material that's an equal or higher rank — which would be diamonds.
Many experts say tungsten rings are safer to wear because they will break/shatter when they come under great amounts of pressure. Versus a solid gold ring that will bend around the finger and cause more damage.
Not only can it withstand a great deal of wear and tear, you can expect your tungsten rings to maintain their finish for years. For active workers who work round the clock, they can wear their ring and practically forget about it; that's how durable it is.
Although the tungsten carbide used in jewelry usually does contain some nickel, this metal usually constitutes a small part of the final mixture. That's why you shouldn't worry about skin irritation if you are allergic to nickel and plan on wearing tungsten carbide jewelry.
Tungsten carbide has been used in industrial cutting applications for nearly a century. In such a setting, where cuts are controllable and repeatable, its high durability and wear resistance allow it to outperform steel tools, cutting faster and leaving a better surface finish on machined parts.
At room temperature, tungsten does not react with water. At room temperature, tungsten does not react with air or oxygen. At elevated temperatures (red hot), the trioxide tungsten(VI) oxide is formd. Finely divided tungsten metal is pyrophoric.
According to the fact sheet provided with the cube, “The addition of these alloying elements improves both the ductility and machinability of these alloys over non-alloyed tungsten, which can be brittle.” The addition of those other elements brings the cube's density down to 18 g/cm^3.
Calcium Carbide is a dangerous and corrosive chemical. Carbide ripened fruits on consumption cause several harmful effects to human health. As discussed earlier, CaC2 has cancer causing properties and contains traces of arsenic and phosphorous hydride.
Silicon carbide is toxicologically safe and can be used in the food industry.
* There is limited evidence that Silicon Carbide causes cancer in animals. It may cause cancer of the lungs. * Many scientists believe there is no safe level of exposure to a carcinogen. Such substances may also have the potential for causing reproductive damage in humans.
