Chatter Free Tungsten Alloy; Super Chatter Free / Diemitech Tungsten Alloy; Tungsten, Nickel and Iron Alloys. Tungsten, Nickel and Iron Alloys (HD17D, HD17.5, HD18D, HD18.5) We offer several tungsten, nickel and iron alloys, comprised of different amounts of the various metals. For detailed information on the composition of our HD17D, HD17 Rhenium alloy wire thinner than a human hair is able to withstand more than seven kilograms of gravity. In addition, rhenium has other electrical properties such as high resistance, with resistivity 3.84 times to tungsten. Its modulus of elasticity and mechanical properties are similar to iron. Natural rhenium consists of two isotopes Re187 and

The Effect of Rhenium Addition on Microstructure and

Sep 20, 2018In this study, the effect of rhenium addition (2, 4, and 6 wt pct) and building orientation (0 and 90 deg) on the microstructure and corrosion resistance of Inconel 718 (IN718) alloy processed by selective laser melting (SLM) was investigated. Microstructure characterization showed that the as-built IN718-Re alloys

A good deal of the rhenium extracted is made into super-alloys to be used for parts in jet engines. Not surprisingly for a transition metal, rhenium is also a good catalyst. In fact a combination of rhenium and platinum make up the catalyst of choice in the very important process of making lead-free

Rhenium Pellets. Titan's rhenium pellets are ideal for alloy melting. Standard packaging includes argon cover gas for safe storage in small increments. Whether your application is land based turbines or high performance jet engines, buying from Titan ensures the highest quality Rhenium

Jan 30, 2018Alloys are mixtures of metal atoms that arrange themselves into specific crystal structures. To understand how these materials work, and the contribution of rhenium to their integrity at high temperature, it helps to have in your mind an image of an urban plan, with blocks of buildings interspersed by roads.


Native Elements and Minerals List

Nov 03, 2019Native elements are chemical elements that occur in nature in an uncombined or pure form. Although most elements are found only in compounds, a rare few are native. For the most part, native elements also form chemical bonds and occur in compounds.

American Elements manufactures Silver Rhenium Alloys in varying compositions and forms such as powder, plate, rod, wire, and sputtering target. We offer standard sizes and shapes in addition to manufacturing unique custom alloys which are tailored to customer requirements. Bulk quantites and term contracts are available for all of our alloy materials.

Oct 06, 2019Rhenium is used in superalloys in jet engine parts and is also used in the process for making lead-free petrol. Rhenium's main use is as a component of high-temperature superalloys which are used in jet engine parts. Aviation companies are trying to find alternatives to these alloys that use less or even no rhenium.

Some molybdenum contain from 0.002% to 0.2% rhenium. More than 150,000 troy ounces of rhenium are now being produced yearly in the United States. The total estimated Free World reserve of rhenium metal is 3500 tons. Rhenium metal is prepared by reducing ammonium perrhentate with hydrogen at elevated temperatures.

Oct 17, 2012A nickel-base superalloy is disclosed. The superally includes aluminum, cobalt, chromium, molybdenum, tantalum, titanium and tungsten, in addition to nickel, as alloy constituents, wherein rhenium can additionally be contained and the rhenium content is less than or equal to 2 wt. % and wherein the titanium content is greater than or equal to 1.5 wt. %.

i FOREWORD Listed herein are designations and chemical composition limits for wrought aluminum and wrought aluminum alloys registered with The Aluminum Association. Numerical designations are assigned in accordance with the Recommendation—International Designation System for Wrought Aluminum and Wrought Aluminum Alloys

Uses of Rhenium: it is added to high-temperature superalloys that are used to make jet engine parts, making 70% of the worldwide rhenium production. Another major application is in platinum-rhenium catalysts, which are primarily used in making lead-free, high-octane gasoline.

Rhenium is an inert metal with no biological affect. MoRe has superior hydrophilicity (CA 373) compared to Titanium (CA 583), a key factor in cell adhesion, migration and replication. Pre-osteoblast cell seeding was found to be equivalent between MoRe and Titanium alloy

Molybdenum Rhenium (MoRe) as a Biologically Superior

Rhenium is an inert metal with no biological affect. MoRe has superior hydrophilicity (CA 373) compared to Titanium (CA 583), a key factor in cell adhesion, migration and replication. Pre-osteoblast cell seeding was found to be equivalent between MoRe and Titanium alloy (10,000 cells/cm2).

When annealed this metal is very ductile and can be bent, coiled, or rolled. [12] Rhenium-molybdenum alloys are superconductive at 10 K ; tungsten-rhenium alloys are also superconductive [13] around 4–8 K, depending on the alloy. Rhenium metal superconducts at 1.697 0.006 K. [14] [15] read more

The number of electrons in each of rhenium's shells is 2, 8, 18, 32, 13, 2 and its electron configuration is [Xe] 4f 14 5d 5 6s 2. The rhenium atom has a radius of 137 pm and a Van der Waals radius of 217 pm. Rhenium was discovered and first isolated by Masataka Ogawa in 1908. In its elemental form, rhenium has a silvery-white appearance.

Readily available as powdered or formed materials, our standard products include pure rhenium, molybdenum-rhenium in 41.5%, 44% and 47.5% Re alloys, and tungsten-rhenium in 5% and 25% Re alloys. And we can custom formulate materials to the specific composition that's
