In case you are wondering, tungsten is the new gold! Tungsten carbide wedding bands have gained prominence in the past few years as a result of its unique features and all the sophisticated wedding band designs crafted out of tungsten.
Tungsten has very unique features that make it one of the best metals for designing men’s wedding bands. Pure tungsten is difficult to craft with, so tungsten carbide is the metal used in all the tungsten jewelry. Here are some qualities of tungsten carbide wedding bands:
1.Highly durable
Tungsten is a very strong metal and its name was coined from two Swedish words; tung and sten, which mean a heavy stone. True to this translation, tungsten is a very strong and a heavy metal. This strength contributes to the durability of any item designed out of the metal. Though this makes tungsten carbide brittle, there are very few cases of broken wedding bands reported.
This durability also makes tungsten carbide wedding bands scratch resistant meaning that even after wearing this ring for over a decade, it will still look as good as new.
2.Ability to withstand heat
As a result of its strength, tungsten carbide can withstand extremely high temperatures and it doesn’t expand at temperatures which normal metals expand.
3.Resistant to corrosion
While wearing your wedding band, you may find yourself touching some acidic compounds, even though this could be a concern when wearing gold or any other metal, it isn’t when wearing tungsten carbide wedding bands. Tungsten carbide’s resistance prevents your finger from turning green because it doesn’t react with the acid.
4.Hypoallergenic
When looking for wedding bands, most people look at the allergy properties of a metal. This is because a big population is allergic to metals and it could be annoying to start scratching your fingers within days or even on the wedding day because you are massively allergic to the wedding band metal.
As a result, and to prevent any of these embarrassing things from happening, tungsten carbide wedding bands come highly recommended as they are totally hypoallergenic. Some of the tungsten carbide wedding bands are available on Tungsten Rings.com.
5.They can be styled
Even though it is impossible to resize tungsten carbide wedding bands, there are many stylish designs that are applicable to these wedding bands. Most exotic inlays are found on tungsten wedding bands and you can also get unique finishes and textures on these wedding bands. They can also be used alongside another metal like titanium resulting in unique wedding bans variations.
6.Color variety
Besides the normal grey tungsten carbide wedding bands, you can also get second generation tungsten carbide wedding bands that are black. Since there has been a higher demand for darker and more masculine wedding bands, the black tungsten carbide wedding bands have been flying off shelves. You should however, ensure that the black band has a scratch resistant inlay.
In conclusion, tungsten carbide wedding bands are taking the market by storm. As an alternative wedding band material preferred by many men, it is relatively expensive but the price you pay for the band is totally reasonable. Other alternative metals include palladium, titanium, cobalt, meteorite, ceramic, or the stainless steel Damascus.

Cemented carbide, which consists of fine particles of carbide cemented into a composite by a binder metal, is an extremely hard material frequently used in mechanical and automotive engineering and the building materials industry. Excitingly for those industries, researchers have now managed to produce 3D printed cemented carbide tools using a binder jetting 3D printing technique. According to the researchers, these 3D printed tools are of comparable quality to those produced using conventional methods, and can be made into more complex shapes.
As an expert in the field of hard metals, researcher has for decades developed ceramic carbides by means of uniaxial or cold isostatic dry pressing, extrusion and injection molding, and shape cutting. These methods were employed to produce reliable cutting, drilling, pressing, and stamping tools made of tungsten carbide. Despite the reliability of those tools, however, Fraunhofer IKTS still faced a problem when it needed to create complex geometries, such as helical or meandering cooling ducts inside a component. These features could only be implemented at a high cost, and were often discarded altogether.
By developing a 3D printed method for cemented carbide tools, which is now able to create such designs with ease. It is known that through resource-saving and tool-free 3D printing, even complex, individualized ceramic geometries can be realized quickly.
The particular 3D printing method used by the researchers are form of binder jetting. During this process, powders or granules of a ceramic hard material, such as cemented carbide tools, are deposited layer by layer and wetted by the print head using a binding material made of cobalt and nickel or iron. This binding material acts as an adhesive between the layers of powder. The researchers aimed to get produce entirely dense components with good mechanical properties, and were even able to selectively adjust the flexural strength, toughness, and hardness of the 3D printed parts by varying the proportion of binder in the carbide: the lower the proportion of binder, the harder the component.
The prototypes manufactured have a binder content of twelve and seventeen percent by weight, and show a structure comparable to conventionally manufactured tools. Through the use of 3D printed for the production of complex green bodies and subsequent sintering under conventional sintering conditions, they achieve components with a typical carbide structure at one hundred percent density. Moreover, it is possible to set a homogeneous cobalt distribution achieving a comparable quality to conventionally produced high-performance tools. 3D printed cemented carbide tools will present at the World Congress & Exhibition.
