Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass.
Rhenium is a heavy transition refractory metal with a melting point of 3,180°C and has the highest modulus of elasticity of all the refractory metals (420 GPa). Rhenium and rhenium containing alloys are unique with high melting points, high moduli of elasticity .

NOTE 1—Actual instrument range might vary from manufacturer to manufacturer and according to sample size. 1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the
Rhenium and rhenium containing alloys are unique metals with high melting points, high moduli of elasticity and high temperature mechanical properties. The most common rhenium containing alloys are molybdenum-41wt% rhenium (Mo41%Re) and molybdenum-47.5wt% rhenium (Mo47.5%Re).
RE0434 Rhenium-Molybdenum Wire, Rod, Tubing, Board. As a Rhenium supplier, Stanford Advanced Materials provides our customers with Molybdenum-rhenium products including wire, plate, rod tubes and custom machined parts. Typical rhenium concentrations of our Mo/Re products are 41%, 44.5% and 47.5%, so called 50/50 Moly Rhenium alloy.
Rhenium is the most recently discovered refractory metal. It is found in low concentrations with many other metals, in the ores of other refractory metals, platinum or copper ores. It is useful as an alloy to other refractory metals, where it adds ductility and tensile strength.

Rhenium - Atomic Mass - Atomic Weight - Re. The Rhenium atomic mass is the mass of an atom. The density of a substance strongly depends on its atomic mass and also on the atomic number density.
8:30 am. RHENIUM AS AN ALLOY ADDITION TO THE GROUP VA METALS: R.W. (Bill) Buckman Jr., Refractory Metals Technology, P.O. Box 100551, Pittsburgh, PA 15236 The anomalous effect rhenium has on the ductility of the Group VIA elements Mo, W, and Cr is not observed in the Group VA metals .
Uzbek Refractory and Heat Resistant Metals Integrated Plant is a complex enterprise infield of manufacture tungsten, molybdenum, rhenium, and alloys on their basis. There is a special technology of imputing rhenium from molybdenum concentrates, which contains from 300 GR. to 700 GR. rhenium per each 1 ton of concentrate at the enterprise.
Aug 01, 1995· A molybdenum-rhenium alloy having an excellent low temperature ductility paired with an excellent high temperature strength. The alloy consists, essentially in % by weight, of 42 up to <45% Re, up to 3% each of W, Y, Rh, Sc, Si, Ta, Tb, V, Nb or Zr at which the sum of said elements is no greater than about 5%, the remainder being Mo besides normally present impurities.
ship between these metals and the neigh- bouring transition metal, rhenium. "It is apparent," write the authors, "in considering rhenium and the (above four) platinum-group metals we are really talking about one family"; and they propose that the family should be termed the "refractory noble metals" .

Rhenium Alloys, Inc. Datasheets for Refractory and Reactive Metals Refractory metals are a class of metals that are extraordinarily resistant to heat and wear and have extremely high melting points. Reactive metals have a strong affinity for oxygen and nitrogen at elevated temperatures and are highly resistant to corrosion at low temperatures.
Rhenium (Re), a silvery gray metal that is characterized by high hardness and density, is one of the rarest chemical elements.It can only be re-rolled at red-hot spots and has one of the highest melting and boiling temperatures after tungsten.. This metal is obtained .
