Tungsten?What is Tungsten? It has the highest melting point, lowest coefficient of expansion and lowest vapor pressure of any metal. It is also corrosion resistant and does not break down or decompose. Due to its unique attributes tungsten has few, if any, replacements in a majority of its industrial applications. HARDNESS Second only to diamond (tungsten carbide) Industrial applications - high speed cutting tools, heavy machinery, specialty alloys HEAT RESISTANCE Highest melting point and lowest coefficient of expansion of all metals Industrial applications - jet turbine engines, light bulb filaments DENSITY Greater than lead and uranium Industrial applications - sporting goods (golf clubs, tennis racquets, darts), ballast ENVIRONMENTALLY BENIGN Does not break down or decompose Industrial applications - sports fishing weights, shotgun shot, new applications being developed as an alternative to lead. The dragon... seem to have the biggest deposits but what if everyone started buying from a friendly country such as Canada? A little more... Tungsten (was) once considered an irritating by-product of tin mining, since it ate up the tin ore, reads a statement from BMW, It took a few hundred years for carbides unique properties to be recognized. (Its) heavy like gold, hard as a diamond and dozens of times more heat-resistant than iron. Today, it can be found in the vibration alarm of mobile phones and light bulb filaments, as well as drill and milling bits for industrial machinery used in producing cars. So, if Im reading that correctly, its a rare-Earth thing thats essential in getting different rare-Earth stuff out of the ground. Thats great news, because BMW alone works through some 7 tons (!) of tungsten per year. Using recycled tungsten recovered in its new process will enable BMW to reduces its tungsten-related energy consumption by 70%, and those CO2 emissions by more than 60% as well. Significant numbers, in other words, and numbers that mean rate of destructive mining is going down". Hum... There are smaller deposits in Red Lake Ontario... Gee ... I love having the time to read!
