ΗTLE ALLOYS OF MOLYBDENUM, RHENIUM AND TUNGSTEN. FIELD OF THE INVENTION. This invention relates to molybdenum alloys which possess improved tensile strength and a higher recrystallization temperature while maintaining an adequate level of ductility and corrosion resistance.
Rhenium improves the properties of tungsten. Tungsten-rhenium alloys are more ductile at low temperature, allowing them to be more easily machined. The high-temperature stability is also improved. The effect increases with the rhenium concentration, and therefore tungsten alloys are produced with up to 27% of Re, which is the solubility limit.
Tungsten-rhenium alloy wire Firmetal, 2018-05-11 09:22:00 PM. Rhenium tungsten wire (tungsten rhenium alloy wire) or Sapphire tungsten-rhenium alloy wire (tungsten rhenium alloy wire for Sapphire) is base in rhenium tungsten alloy elements, is a kind of tungsten alloy.The typical rhenium content in the alloy is 1%, 3%, 5%, 20%, 25% and 26%, etc.
A molybdneum, rhenium, and tungsten alloy having an improved erosion, ductility, strength and a higher recrystallization temperature. The alloy may be fabricated into equipment which is useful for manufacturing chemicals such as a hydrochlorofluorocarbon.
Concept Alloys' medical wire and tubing is suitable for a wide range of applications, primarily for various surgeries. The size range, ductility and specific size/shape quality properties of Concept Alloys' tungsten-rhenium enables our medical wire and tubing to be customized for specific cardiovascular and diagnostic applications.
Nov 16, 2017· What Is Rhenium And What Are Its Applications? Rhenium is chemical element that was discovered in 1908. ... Addition of rhenium in tungsten helps improve its properties; thus making the tungsten-rhenium alloys ductile and easy to work with at low temperatures. The stability of tungsten at high temperatures grows with the addition of Rhenium.
Rhenium ring -- 24 karat (99.99% pure) Wedding bands have traditionally been made of gold with 14 karat (or 58.5% pure) being the most common and 18 karat (or 75% pure) also available. Gold is too soft to make a durable ring out of at 24 karat purity (at least 99.9% pure).
About Pure Rhenium Pure rhenium is an important material for many scientific instrument filaments, as well as other electron and ion source filaments. Most rhenium naturally occurs in porphyry copper deposits. Hydrogen reduction is used to convert ammonium perrhenate to pure rhenium powder. The pure rhenium powder is pressed and sintered into ingots.
Rhenium is a rare metal with unique properties that make it ideally suited for today's most powerful engines and critical chemical reactions. Eagle Alloys is a premier rhenium metal supplier providing rhenium in both its pure form and most popular alloys.
Rhenium Alloys supplies pure Tungsten, and Tungsten alloys – Tungsten-Copper and Tungsten-Rhenium. Tungsten is commonly used in filaments, electric bulbs, electric tubes, heating elements in high-temperature furnaces, high speed tools, and in the aerospace and automotive industries.
The refractory metals consist of a group of five materials: tungsten, molybdenum, tantalum, niobium and rhenium. These metals share a number of common characteristics, to varying degrees, including: Extremely high melting point — particularly tungsten, molybdenum and tantalum — making them valuable for processing molten metals and minerals.
among these are several works making predictions for ReB 2-structured WB 2 and for rhenium/tungsten diboride solid solutions.20,23,31,32,36−38 As a result, experimental realization of such a system would be an ideal test of these theoretical predictions. For the reasons mentioned above, solid solutions employing WB
