Wedding Bands Made of Carbide Contain Other Materials Known as Binders

Wedding bands made of carbide contain other materials known as binders, usually metals such as nickel and cobalt. Cobalt has been known to cause allergic reactions on the skin of the wearer, so many manufacturers are turning toward substitute materials. Despite the common misconception that carbide rings cannot be removed in emergency situations, the jeweler's saws used in emergency rooms and jewelry shops can cut through any material that a ring might be made of.

It is important to note that tungsten carbide is made in nearly two dozen different grades that have different properties, depending on what each will be used for. They are almost all variations of just a few parameters: grain size, hardness, and the degree to which a binder is used. Generally, the higher the percentage of the finished product that is composed of binding materials like nickel, the softer it will be and the more it will wear. The size of the original powder grains makes slightly less difference, but can affect the amount of shock that the product will be able to withstand.
