3724 Ashwood Drive Essex, Florida (PressExposure) April 16, 2009 -- Tungsten carbide is one of several kinds of metals that have many applications. In the military, tungsten carbide is often used in armor-piercing ammunition, in place of uranium when uranium is depleted or not politically acceptable. W2C projectiles were first utilized by German Luftwaffe tank-hunter squadrons, which used 37-mm autocannon equipped Junkers Ju 87G dive bomber aircraft to destroy Soviet T-34 tanks in World War II. Owing to the limited German reserves of tungsten, tungsten carbide material was reserved for making machine tools and small numbers of projectiles for the most elite combat pilots, like Hans-Ulrich Rudel. It is an effective penetrator due to its high hardness value combined with a very high density. However, this is not the only use for tungsten carbide. It is also utilized in making tungsten wedding band.
Wedding rings made from tungsten carbide can be found on most jewelry shops and online jewelry shops around the world. Tungsten carbide is the primary material used in these wedding bands. Rings made of this metal possess a lustrous dark hue that is often buffed to a mirror finish. Their color is more similar to that of hematite than to that of platinum. Compared to a normal tungsten wedding band, the finish of tungsten carbide ring is highly resistant to scratches and scuffs, holding its mirror-like shine for years.
A common misconception held concerning tungsten wedding band is that they cannot be removed in the course of emergency medical treatment, requiring the finger to be removed instead. Emergency rooms and many full-service jewelry repair shops are equipped with jewelers' saws that can cut through tungsten carbide rings without injuring the patient when the ring cannot be slipped off easily. It is because of the hardness of these rings that standard ring cutters are unable to cut tungsten carbide rings. However, tungsten carbide rings can be removed in an emergency situation by cracking them into pieces with tooling such as standard vice gripâstyle locking pliers.
Many manufacturers of this emerging jewelry material state that the use of a cobalt binder may cause unwanted reactions between the cobalt and the natural oils on human skin. According to some people, skin oils cause the cobalt to leach from the material. This is believed to cause possible irritation of the skin and permanent staining of the jewelry itself. To address this issue, many manufacturers now advertise their jewelry to be "cobalt free". This is achieved by replacing the cobalt with nickel as a binder.
