Another significant utilization of tantalum is for electronic components and due to its absorption properties, it is an excellent getter of residual gasses in evacuation tubes.

Molybdenum's remarkable properties offer ascent to procedures and applications in hardware, aviation, atomic and metal working businesses which would not be conceivable with a considerable lot of the more typical metals and compounds. A portion of the all the more fascinating properties of Molybdenum identify with high temperature applications - high temperature quality, great warm properties, great electrical conductivity, low coefficient of development and low vapor weight at lifted temperatures. Molybdenum is a refractory metal that is very useful in many industrial processes and applications that would not be possible with many of the more common metals and alloys. Refractory metals and alloys are extraordinarily resistant to heat and have unique physical properties. Because of these properties Molybdenum is useful in many high temperature applications where high melting points are required. Molybdenum also exhibits good strength at elevated temperatures making moly useful in furnace, aerospace, and similar applications. And Molybdenum's good thermal and electrical conductivity and low coefficient of expansion make it a useful metal in electronic/electrical and glass-to-metal sealing applications. Molybdenum also has nuclear energy applications, and is employed as a catalyst in the petroleum refining industry. Molybdenum is also an essential trace element in plant nutrition, and Molybdenum sulfide is useful as a lubricant, especially at high temperatures where oils would decompose.

If you require other forms of Niobium, please call one of our materials experts; our sales people are very knowledgeable and can assist you. We can cut, slit, shear, or center less grind Niobium to your exact specifications, and we also have tremendous versatility when it comes to custom sizes, packages, and unusual materials. Niobium, also termed Columbium, is a shiny grey metal that takes on a bluish tinge when exposed to air at room temperature. Due to its low capture cross section for thermal neutrons, Niobium has application in the nuclear industry. Niobium can be electrically heated and anodized to a wide variety of colors that makes it very attractive in the jewelry industry. Niobium is added to iron or nickel to produce alloys in the aerospace, medical and electronics industries. Niobium, additionally named Columbium, is a gleaming dim metal that goes up against a somewhat blue tinge when presented to air at room temperature. Because of its low catch cross area for warm neutrons, niobium has application in the atomic business. Niobium can be electrically warmed and anodized to a wide assortment of hues that makes it exceptionally alluring in the adornments business. Niobium is added to iron or nickel to create amalgams in the aviation, therapeutic and gadgets businesses.

NUFIT PIPING SOLUTIONS stocks Tungsten in a variety of forms and dimensions. Below are most of the standard stock form/sizes. If you do not see the size or form of Tungsten that you require, please call one of our materials experts; our sales people are very knowledgeable and can assist you. We can cut, slit, shear, or center less grind Tungsten to your exact specifications, and we also have tremendous versatility when it comes to custom sizes, packages, and unusual materials Many practical applications of Tungsten are based on its high melting point and density and its low vapor pressure. Tungsten is an excellent material for high vacuum technology, dimensional stability, glass seals and furnace construction. In addition, Tungsten's high density gives it a capacity to absorb radioactive radiation. Tungsten has found wide use as additives to steel to enhance physical properties and an alloy with nickel, copper and iron to provide high density machinable materials. Numerous reasonable uses of tungsten depend on its high liquefying point and thickness and its low vapor weight. Tungsten is an astounding material for high vacuum innovation, dimensional strength, glass seals and heater development. Furthermore, tungsten's high thickness gives it an ability to ingest radioactive radiation. Tungsten has discovered wide use as added substances to steel to upgrade physical properties and an amalgam with nickel, copper and iron to give high thickness machinable materials.

Nichrome is a nickel-chromium resistance alloy for operating temperatures up to 2150° F. It is non-magnetic, highly corrosion resistant and has a lower coefficient of resistance than other heater element alloys. Typical Applications for the material include flat irons, ironing machines, quartz tube heaters, cartridge elements, etc. The lack of reactivity to MgO refractories make it the most suitable alloy for enclosed heater elements especially in higher temperature ranges.

Zirconium has a melting point of 1855 degrees C or 3371 degrees F. Zirconium is a highly corrosion resistant metal that is us used for many products. Some include pumps, valves, nuclear applications, chemical processing, reactor vessels, heat exchangers and more. The nuclear power industry uses nearly 90% of the zirconium produced each year. Zirconium is also used as an alloying agent in steel, to make some types of surgical equipment and as a getter, a material that combines with and removes trace gases form vacuum tubes. Zirconium is weldable and formable. Zirconia for use as a refractory is made by two processes. A stabilising oxide, e.g. MgO, is added in the desired amount, typically 6 mol%, briquetted and fired to a temperature above 1600°C. This converts the main body of the zirconia to the cubic phase.The fired briquettes are then ground in a ball mill to lessthen 10 mm, using steel grinding media. The powder is then washed in dilute HC1, to remove impurities and used to form a casting slip (pH@ 3). Drying produces a shrinkage of 2-4% and following firing at typically 1900°C, a further contraction of ~ 15% occurs.
