Tungsten Alloy Technology s. AUTHOR(S) papers are indicative of the present interests of the Army in tungsten alloys for kinetic energy penetrator applications. The papers are com- High Temperature Engine Materials Technology Program ýHITEMP), and the National Aerospace Plane (NASP) Program, has brought a namber of new materials. Midwest Tungsten Service tungsten copper alloys are the perfect choice where high density, high thermal conductivity, or low thermal expansion are important. Electrical contacts, heat sinks, and resistance welding electrodes are all applications where MTS tungsten copper alloys can do the job. Check the options and properties below to determine.
Specialized methods make possible the processing of pure tungsten into rod, sheet, and wire for a wide variety of high temperature applications including incandescent lamp wire, TIG welding electrodes, and high temperature heat shielding. Another important industrial property of tungsten is its high density of g/cc ( lbs/in3). In addition to the pure metal, Elmet provides tungsten-based alloys that achieve specific performance characteristics: Tungsten – Potassium (WK) Potassium-doped product is targeted for use where high temperature, non-sag wire properties are required in the lighting and electronic industries.
Tungsten Alloys Eagle Alloys Corporation can offer a wide variety of High Density Machinable Tungsten Alloy sizes and compositions for immediate shipping or we can supply custom grades, shapes and finished parts with a short lead time. Eagle Alloys can supply alloys ranging from 90% to 97% Tungsten and contain nickel.

Assessment of Creep Capability of HSR-EPM Turbine Airfoil Alloys. Article. Two approaches presented in Sections W laminates made of W foils, Tungsten-wire-reinforced tungsten composites with pseudo-toughness are very promising for an improved fracture behavior of W-based components.
The first one relies on a brazed laminate made of a. Tungsten alloy is expected to be used as a novel mold material for glass parts, because it has partially better thermal properties than the sintered tungsten carbide and the CVD-silicon carbide as shown in Table rmore, the tungsten alloy is machinable with ordinary carbide tools, and it can be used for the glass molding without the coatings because of its superior thermochemical stability.

By refining the microstruc- ture of the tungsten heavy alloys, the mechanical proper- ties can be improved. The conventional processing route includes mixing the desired amount of elemental powders, followed by cold. Metallic tungsten and tungsten alloy mill products account for about 16% of consumption.
Tungsten and tungsten alloys dominate the market in applications for which a high-density material ( g/cm 3) is required, such as kinetic energy penetrators, counterweights, flywheels, and governors. Other applications include radiation shields and x.
Precipitation hardened alloys dominate high strength applications in the - °F ( - °C) temperature range. These alloy systems consist of an austenitic matrix strengthened by precipitates of nickel and aluminum, titanium or columbium (Ni 3 Al, Ni 3 Ti, Ni 3 Cb) and solid solution-strengthening elements such as molybdenum.
All Wolfmet tungsten alloy grades are reasonably corrosion resistant in both acid and alkaline environments and can easily be plated or painted if necessary. They are easy to clean, non-toxic and non-radioactive. Magnetic tungsten alloy Manufactured with a binder of iron and nickel, our magnetic alloys have a tungsten content of % by weight.
The potential of tungsten-2 percent thoria, tungsten, and tungsten-1 percent thoria wire reinforced nickel-base superalloy composites for turbine bucket applications was evaluated based on stress-rupture strength, oxidation, and impact resistance.
