Ferro Tungsten Wo Wolframite, (Fe,Mn)WO 4, is an iron manganese tungstate mineral that is the intermediate between ferberite (Fe 2+ rich) and hübnerite (Mn 2+ rich). Along with scheelite, the wolframite series are the most important tungsten ore minerals. Wolframite is found in quartz veins and pegmatites associated with granitic intrusives. Crystal habit: Tabular to short prismatic crystalsCrystal class: Prismatic (2/m), (same H-M symbol)Mohs scale hardness: 4-4.5Crystal system: MonoclinicFerro Tungsten High Wolfram Ferro Tungsten Ore tungsten ore extraction equipment: 1.CE,ISO9001:2008 2.Big air inlet,low energy consumption 3.Rational ore pulp recycle Ferro Tungsten Wolfram Ferro Tungsten Particle Size: (5-100)mm It is to act as the tungsten additive in steel smelting & alloy material Tungsten carbide is used in mining and drilling equipment, wear-resistant surfaces and molds. In Ni-Co structured super alloy steels, the filaments which are the lamp wires of the bulbs are also tungsten products. It is also used in high alloy products in space technology. Iron alloy ferro tungsten is used in the production of tool steels. People also ask Why was Ferro-Ferro steel introduced in 1893? This rather expensive procedure limited the application of W alloyed steels because of the high price. In 1893 a new tungsten ferro alloy was introduced containing up to 80 % tungsten, called ferro- tungsten (Fe-W), which was much cheaper. Fe-W has lower melting temperatures, faster dissolution in the liquid steel and a higher W yield. The European ferro-tungsten price climbed to its highest levels since the beginning of April on increased spot market interest with more than 70 tonnes of business reported to Fastmarkets in the week to April 30. Tighter concentrates supply from China is also supporting higher
