Refractory Metals and Alloys

For applications where high melting points, good strength at elevated temperatures, good thermal and electrical conductivity, low coefficient of expansion, and low vapor pressure at elevated temperatures are required (e.g. furnace components, heat exchangers/coils, welding electrodes, etc.).

Molybdenum

Molybdenum’s unique properties give rise to processes and applications in electronics, aerospace, nuclear and metal working industries which would not be possible with many of the more common metals and alloys. Some of the more interesting properties of Molybdenum relate to high temperature applications - high temperature strength, excellent thermal  properties, good electrical conductivity, low coefficient of expansion and low vapor pressure at elevated temperatures.

Vacuum Furnace Molybdenum

Our new, Vacuum Furnace Molybdenum Component Stocking Program (VFM) offers an expanded line of Molybdenum products to provide you with replacement materials for support structures, furnace rails, heat shields, heating elements, evaporation boats, crucibles, and other Molybdenum components you need.

Tungsten

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.

Tantalum

Tantalum is famous for its resistance to corrosion by acids; in fact, below 150˚C, tantalum is almost completely immune to corrosion by aqua regia. Due to its resistance to attack by body fluids, tantalum provides an excellent material for medical devices. Another major use of tantalum is for electronic components and due to its absorption properties, it is an excellent getter of residual gasses in evacuation tubes.

Niobium (aka Columbium)

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 colours 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.

Rhenium

Among the highest density element and melting point, rhenium does not have a ductile to brittle transition temperature and does not form carbides. High resistivity, combined with low vapor pressure, it is an ideal material for filament applications. Excellent resistance to corrosion, resists acid attack and the mechanical effects of electrical erosion. Rhenium has a beneficial effect as an alloying addition with other refractory metals as it greatly enhances the ductility and tensile strength of these alloys.

TZM Molybdenum

Molybdenum TZM is an alloy of 0.50% Titanium, 0.08% Zirconium and 0.02% Carbon with the balance Molybdenum. TZM alloy is manufactured by either P/M or Arc Cast technologies and is of great utility due to its high strength/high temperature applications, especially above 2000°F.

Tungsten Alloy

Tungsten alloys, which contain elements such as nickel, copper and iron, produce a host of alloys which have engineering properties similar to steel, are relatively easy to machine, and can be plated or painted to enhance their corrosion protection. These alloys are approximately 50% denser than lead resulting in a higher concentration of mass in a limited area.

ED FAGAN Europe Ltd. supplies the highest quality special purpose alloys and metals for Aerospace/Aviation, Defence, Magnetic, Electronics, Telecommunications, Lighting, Optical, Ceramics, Heat Treating, Medical, and other high-technology industries.
