These companies often have considerable power and influence, and as a result are often criticised for their actions. One of the most famous of such cases was the problem faced by Nestlé in selling its baby milk in Africa. Critics pointed out that Nestlé was pushing the product on people when it was likely to cause harm to babies. According to a study in the British Medical Journal in 2003, the company was ignoring a code of conduct on marketing the productto countries in Africa. In addition, events like the Bhopal chemical explosion in 1984 have attracted much criticism. The incident took place in the Indian city of Bhopal and resulted in the death of more than 3,000 people, according to official figures. The plant belonged to the American chemical multinational Union Carbide.
No. Tungsten is an element, where as tungsten carbide is an alloy, or a mixture of elements (tungsten, nickel, tantalum, niobium, titanium, and chromium). Tungsten carbide is much easier to work into styles and designs, but does not change the hardness of the metal.
"Carbide" as used in "Carbide Drills" and "Carbide Saws" is the alloy Tungsten Carbide. Chemically the material is either Tungsten Carbide (WC) or Tungsten diCarbide (WC2). Carbide is used because of its hardness.
According to several publications Tungsten Carbide measures a 9 on the Mohs Hardness Scale. A Diamond measures 10 on the Mohs Hardness Scale meaning it would require a diamond to scratch Tungsten Carbide. Tungsten has an official hardness on the Mohs Hardness Scale of 9, but can be as hard as 9.5 on the Mohs Hardness Scale making it almost scratch proof. Now if you are talking about pure Tungsten the hardness is only 7.5 on the Mohs Hardness Scale making it softer than Sapphire, Ruby, Emerald, Alexandrite, Topaz and Spinel. When Tungsten is compounded into Tungsten Carbide the hardness rises greatly sometimes almost equaling the hardness of Diamonds. Tungsten Carbide is five times harder than 316L Surgical Grade Stainless Steel.
Yes, tungsten carbide is considered a brittle material due to its high hardness and low ductility, making it prone to cracking or breaking under stress.
Yes, tungsten carbide is brittle and can fracture under certain conditions due to its high hardness and low ductility.
Tungsten carbide belongs to the category of ceramics or "hard materials." It is a compound made of tungsten and carbon and is known for its exceptional hardness and durability, making it widely used in applications requiring wear and abrasion resistance.
No, tungsten carbide is highly resistant to tarnishing or corrosion due to its hardness and chemical inertness. This makes it a popular choice for jewelry and industrial applications that require durability and longevity.
Tungsten carbide rings cannot be resized. Due to their extreme hardness and durability, tungsten carbide rings cannot be resized like traditional metals such as gold or silver. It is recommended to ensure the correct size before purchasing a tungsten carbide ring.
In the context of tungsten carbide, the solute is tungsten carbide itself (the solid compound of tungsten and carbon) and the solvent would be the medium in which tungsten carbide is dissolved, which is typically a liquid like cobalt or nickel in the case of cemented carbide materials.

Cutting bits are made of tungsten carbide due to its exceptional hardness and wear resistance, which significantly enhances their durability and effectiveness in machining and cutting applications. Tungsten carbide can withstand high temperatures and pressures, making it ideal for high-performance tools. Additionally, its brittleness is balanced by its strength, allowing for sharp cutting edges that maintain their integrity during use. This combination of properties makes tungsten carbide a preferred material in the manufacturing of cutting tools.
The weight of tungsten carbide is approximately 0.283 pounds per cubic inch, which translates to about 8.1 grams per cubic centimeter. This high density makes tungsten carbide a popular material for applications requiring durability and hardness, such as industrial tools and jewelry. Its significant weight contributes to its effectiveness in various high-stress environments.
