Opened in 1918, Union Carbide's Pine Creek Mine was once the largest tungsten producer in the United States. Located in the Eastern Sierra, northwest of Bishop, California. In its heyday (1940 – 1990) the mine produced 162,000,000 tons of ore and 8,350,000 20-pound "units" of tungsten oxide with a total value of more than $400,000,000.

The binder in most grades of Tungsten Carbide is cobalt. The other binder used is nickel. The binder is added as a percentage by weight varying from 3% to 30%. The amount of binder used is a very important factor in determining the properties of each grade. As a rule of thumb the lower the cobalt content the harder the material will become.
