Refractory metals like tantalum and niobium are very robust and unique materials, which both exhibit high melting points, high corrosion resistance, excellent chemical resistance and biocompatibility.
Welding of Reactive and Refractory Metals ... (Niobium) The reactive metals are: ... The reactive and refractory metals were originally used in the aerospace industry and are now being welded for more and more requirements. These metals share many common welding …
The term 'refractory metal' is used to describe a group of metal elements that have exceptionally high melting points and are resistant to wear, corrosion, and deformation. Industrial uses of the term refractory metal most often refer to five commonly used elements: Molybdenum (Mo) Niobium (Nb) Rhenium (Re) Tantalum (Ta) Tungsten (W)
Niobium has a melting point of 4474 F, which is 256 degrees lower than that of molybdenum. Development of niobium metal and its alloys for elevatedtemperature structural applications was started only a few years ago, but considerable progress has been made since then.

With refractory metal as the matrix, the alloys added with other elements are called refractory metal alloys, including tungsten alloys, molybdenum alloys, niobium alloys, titanium alloys, vanadium alloys, chrome alloys, rhenium alloys, chromium and zirconium alloys, tantalum and button alloys, etc.
Niobium has many uses, some of which it shares with other refractory metals. It is unique in that it can be worked through annealing to achieve a wide range of strength and elasticity, and is the least dense of the refractory metals.
Niobium belongs to the group of refractory metals. Refractory metals are metals that have a higher melting point than platinum (1 772 °C).In refractory metals, the energy binding the individual atoms together is particularly high.
The refractory metals include niobium (also known as columbium), tantalum, molybdenum, tungsten, and rhenium. With the exception of two of the platinumgroup metals, osmium and iridium, they have the highest melting temperatures and lowest vapor pressures of all metals.
Refractory metals are widely used in various applications because of their unique and desirable properties and behaviors, not least of which is their resistance to corrosion. This group of metals also has extraordinary resistance to wear and heat. These metals are mostly used in the field of engineering, science and metallurgy.
Niobium is also a refractory metal. The refractory metals are a group of exotic metals that can retain their hardness and strength even when subjected to extreme heat and exhibit several other unique properties as well that make them useful for a range of manufacturing processes.
Some felt that perhaps tantalum was an allotrope of niobium Of the refractory metals, tantalum is H. Cross Company can supply tantalum products in wire . Online Chat Send Inquiry. Niobium, Niobium Suppliers and Manufacturers at niobiumsupplier.
Despite niobium’s relatively high melting point, its density is the lowest of all refractory metals, which can make it appealing to the aircraft and jet engine industries. Niobium is also frequently used to make jewelry due to its malleability, hardness, corrosion resistance, and hypoallergenic properties.
What are refractory metals? Refractory metals have one characteristic in common: an exceptionally high melting point. Tungsten, for ... Tungsten, Molybdenum, Niobium, Tantalum and Rhenium. 4 All but Rhenium have a bodycentered cubic structure. Despite the fact that refractory metals …

Refractory metals defined The term “refractory metals” is generally applied to metals that have melting points greater than 2000oC (3630oF). Metals in the group are shown in Table 1. Principal materials in the group are tungsten, tantalum, molybdenum, and niobium, all of which are routinely used in the furnace industry.
Alloying niobium with other metals such as iron, cobalt and nickel enhances its inherent refractory properties without adding weight. This makes niobium extremely valuable in the manufacturing of aerospace industry products such as rocket engines and gas turbines found in airplanes.
Home » Refractory Metals and Alloys » Columbium / Niobium History of Columbium / Niobium Niobium, discovered in 1801 by C. Hatchett, an English Chemist in an ore called columbite, is a metal that is closely related to tantalum.
Refractory metals, molybdenum, tungsten, niobium, tantalum, and rhenium have a number of characteristics in common. They are all BCC metals, and as shown in Figure 1(a) , have some of the highest melting points among the elements.
Like niobium, tantalum is a heattolerant refractory metal with excellent corrosion resistance. Often alloyed with other metals, tantalum is used to make super alloys used in chemical processing, jet engines and nuclear reactors.
