China Domination of Tungsten Causes Fear


U.S. Sen. Robert Casey, D-Scranton, pressed the Department of Defense on Tuesday to speed release of tungsten from strategic stockpiles to preserve jobs at American manufacturers who depend on buying some of that supply.

Casey said in a letter that the industry is "dominated by China," and he was fearful that unless DOD acts quickly, hundreds of jobs will be lost overseas as well as the "intellectual capacity" to make parts necessary for national defense.

Figures from the U.S. Geological Survey show that last year, China produced 83 percent of the world's tungsten and kept a substantial amount for its own consumption. The United States, Europe and Japan consume 55 percent of the world's tungsten production while producing 5 percent, according to Ormonde Mining of Ireland.

Kennametal Inc., which has a plant in China, has expressed concern over the outlook for obtaining certain raw materials to continue American manufacturing operations. The industrial tooling manufacturer is based in Unity.

"It is our understanding that an interruption in the tungsten concentrate feedstock used by American tungsten manufacturers will force the shutdown of several production lines and eliminate hundreds of American manufacturing jobs," Casey said in his letter.

Two years ago, China began restricting exports of rare earth materials used in military weapons as well as domestic uses such as LED screens, other electronic goods and hybrid cars. Several companies outside of China began mining projects, but with mixed success.
Colorado-based Molycorp recently acquired a company to process some of the material in China, where rare-earth engineering is concentrated. Another project in Malaysia has been delayed for environmental reasons.

The Defense Department uses tungsten in "many strategically vital weapons systems," Casey said. He noted the country has 34 million pounds of tungsten reserves and had indicated it plans to release a maximum of 8 million pounds this year.
So far, he said, no tungsten has been released.
