...melting point (3224° F.) was too high for the crude furnaces then in use. As better furnaces were developed, his technique was little used until about 1910 when U.S. scientists, notably General Electric's William David Coolidge, revived it as the only practical way of making ductile tungsten (melting point 6100° F.) from which thin wires for light bulb filaments could then be drawn through holes in diamonds...
Germany's contribution to powder metallurgy came about 1916 when the great Krupp Works learned from the electrical industry to press and sinter mixtures of tungsten carbide with cobalt into the hardest cutting compound known, began producing it commercially. These hard-cemented carbides have a hardness between diamond and sapphire. They are often shaped into cutting tools by another product of powder metallurgy: a solidified mixture of diamond dust and bronze powder. They work without softening at high, cherry-red heats while cutting ordinary armament steels two to ten times faster than cutting tools made of the toughest high...
...from the Door Latch. About 1922 the U.S. electrical industry created a byproduct of its work with tungsten: bearings pressed from copper and iron alloys. Their sponginess was their advantage: the fine continuous pores (up to 40% by volume) can absorb oil, exude it by capillary action as needed. Often they require no further oiling after impregnation; they can be sealed into machinery (e.g., household refrigerators) and forgotten. By 1932 "oil-less" bearings were used for many purposes in automobiles and were in time found to outlive the rest of the machine. Billions of such bearings...
Wrote Hothead Belmonte: "We have received all maps showing the most favorable sites for landing. These show me once more that you [Wendler] and your staff are doing excellent preparation for the realization of our plan in favor of Bolivia. . . . We must destroy the tungsten contract with the U.S. . . . Bolivia does not need American loans. With the victory of the German Reich, Bolivia will need only work and discipline. ... I will fly to Brazil upon your advice and take Cochabamba and Santa Cruz, where I have good friends...
