Hazards of Tungsten Carbide

The most frequently utilized hard metal in manufacturing today, tungsten carbide, is used to make a wide variety of products, including wedding rings, golf clubs and machinery. Tungsten carbide is favored by manufacturers because it is strong, durable and heat tolerant. It is made primarily of tungsten and cobalt and small amounts of other metals such as nickel. Workers exposed to airborne tungsten particles do not appear to have any adverse health effects, but exposure to airborne cobalt particles can have a serious impact on health.
Eye and Skin Irritation
When the eyes and skin are exposed to tungsten carbide, the result is irritation. In addition, repeated exposure can result in allergies to tungsten carbide, as well as to nickel and cobalt.

Respiratory Ailments
Inhalation of tungsten carbide dust can lead to nose, throat and lung irritation. Repeated exposure to tungsten carbide can lead to a range of serious respiratory ailments including asthma, pulmonary fibrosis and hard-metal lung disease.
