Tin and tungsten are critical and strategic minerals to the United States. The basis for such a designation exists in the historic and current (1989) net import reliance of these metals by the United States as a percent of apparent consumption. Estimates by the U.S. Bureau of Mines for 1989 indicate a 73% net import reliance for both tin and ...
WAtM estimated the cost of lifting objects into space at $10,000 per pound, meaning that 200 cubic feet of tungsten rod, which weighs around 24,000 pounds, would cost about $230 million per rod to place into orbit.

Tungsten is a greyish-white lustrous metal, which is a solid at room temperature. Tungsten has the highest melting point and lowest vapor pressure of all metals, and at temperatures over 1650°C has the highest tensile strength. It has excellent corrosion resistance and is attacked only slightly by most mineral acids.
