Tungsten is a hard metal that’s used in many different applications, from manufacturing and aerospace to electronics and energy production. It’s also a popular choice for rings, due to its durability and aesthetics. In fact, tungsten is four times harder than titanium and ten times harder than 18k gold. And despite its impressive strength, tungsten is actually quite malleable, which makes it ideal for making jewelry that’s durable and comfortable to wear.
Tungsten is found in the elements scheelite (CaWO4) and wolframite (Fe, Mn)WO4, and it has the highest melting point of any metallic element. It is also incredibly dense, with a density nearly twice as high as gold and almost as high as uranium. These properties make tungsten the perfect material for jewelry, especially for men’s rings that need to stand up to everyday wear and rough use.
The tungsten we use to make jewelry is created through a process called powder metallurgy and sintering. This involves mixing tungsten powder with a binder, like nickel or cobalt. The mixture is then packed into the desired shape, and heated in a furnace at 2,200°F. The heat and electric currents cause the powders to fuse together, forming a solid piece of tungsten. The resulting material can then be sculpted and refined using diamond tools. Inlays, such as silver, gold, palladium, or diamonds, can be inserted into the tungsten, creating unique and beautiful designs.
One of the most common types of tungsten jewelry is tungsten carbide, which typically consists of 80-85% tungsten and 15% carbon, with or without a nickel or cobalt binder. The higher percentage of carbon in the mix makes tungsten carbide more malleable and easier to work with, while still being durable enough to last a lifetime. Tungsten carbide is also hypoallergenic, which makes it the perfect material for wedding bands and other jewelry that will come into contact with sensitive skin.
Another common type of tungsten jewelry is black tungsten, which is achieved through a process called ion nitriding. This involves coating the tungsten with a layer of nitrogen, which changes its molecular structure, making it more resistant to scratches and dings. The result is a black jewelry piece that’s both durable and elegant.
China tungsten rings are becoming increasingly popular for their durability, style, and affordability. They’re also hypoallergenic and scratch-resistant, so they won’t dent or chip even after a lifetime of wear. In addition, they’re available in a wide variety of styles and finishes to suit any taste, from classic black to brushed gunmetal and even wood inlays.
