أكمل القراءةIn color, platinum is brighter than tungsten carbide which is closer to stainless steel in brightness. However, white tungsten carbide uses a special 5-stage process that bonds a 95% pure platinum group metal to the surface, achieving a look that is as bright at platinum while retaining tungsten carbide's everlasting durability.
أكمل القراءةThe platinum group metals (PGMs) comprise 6 elements, which are platinum, palladium, rhodium, ruthenium, iridium, and osmium. These metals have high melting points, high heat resistance, high corrosion resistances, and unique catalytic properties. Owing to these properties, PGMs are being used widely in many industrial fields, most notably as automobile exhaust …
أكمل القراءةTungsten-platinum alloys also featured as electrical contact materials, but do not appear to be used currently for this. Perhaps due to the limited range of uses of the alloys, the constitution of the tungsten-platinum system has received very little attention, compared for example with the closely related molybdenum-platinum alloys.
أكمل القراءةIn the United Kingdom, platinum 850/tungsten 150 and platinum 900/tungsten 100 are used for findings and other applications for which a very hard alloy is needed. Platinum 850/tungsten 150 has a Vickers hardness of 251 and a density of 19.5. Platinum 900/tungsten 100 has a Vickers hardness of 350 and a specific gravity of 20.3.
أكمل القراءةPlatinum Group Metals. Platinum group metals are unique among the transition metals because (except for osmium) they combine excellent catalytic activity with low chemical reactivity. As a result, the platinum group metals at Ultramet are used primarily for two purposes: protective and catalytic coatings.

أكمل القراءةNano Tungsten Carbide – The Platinum-like Catalyst. In nature, platinum group elements together with gold and silver are known as precious metal elements. Platinum family has platinum, iridium, rhodium, and palladium. The most important value of platinum is not that it is platinum jewelry, but that it is an important industrial catalyst, such ...
أكمل القراءةTungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. Tungsten is a rare metal found naturally on Earth almost exclusively as compounds with other elements. It was identified as a new element in 1781 and first isolated as a metal in 1783. Its important ores include scheelite and wolframite, the latter lending the element its alternate name.
