Supplier of Tungsten and Alloys

Pure tungsten is a hard metal with a color ranging from steel grey to tin white. It can be cut with a metal saw when very pure, but it is brittle and difficult to work on when impure, and is normally worked by forging, extrusion, or stretching. This element has the highest melting point (3 422°C) of all metals, and the highest tensile strength of all metals at a temperature above 1650°C, its Young’s modulus is 406GPa. Because of its very high melting temperature, tungsten is not melted but sintered. Its corrosion resistance is excellent and it can only be slightly attacked by mineral acids.

Tungsten has a wide range of uses. The hardness and density of this metal make it ideal for making alloys of metals used in weaponry, heat sinks, as well as weights and counterweights.
Since its coefficient of expansion is equivalent to that of borosilicate glass, it is used to make glass-to-metal welds (electrodes, electrical passages).

Tungsten-containing superalloys are used to make turbine blades, steel tools and cladding.

It is used as a refractory electrode in TIG welding.
The arc contacts of high-voltage circuit breakers are also partially made of tungsten to withstand the high temperature of an electric arc.

The mining and oil industries, such as the military industry, and the electrical industry use tungsten in a pure or alloyed manner.

Tungsten-rhenium alloy is a solid solution reinforced alloy consisting of a tungsten element as the matrix and a rhenium element.  Rhenium contents commonly used in alloys are 3, 5, 10, 25 and 26.  It is divided into low grade W-Re alloy (Re 5%) and high grade W-Re alloy (Re 15%).
Tungsten-rhenium alloy has better mechanical properties and ductility than pure tungsten, and has high resistivity, which gives it better processing ability and weldability.
Tungsten-rhenium alloy has a series of excellent properties, such as high melting point, high strength, high hardness, high plasticity, high recrystallization temperature, high resistivity, a high thermoelectric potential value, low vapour pressure, low electron working function and low ductility and brittleness transition temperature. Tungsten-rhenium is in the form of wire, rod, plate and sheet.  Wire materials make up the vast majority and are mainly used as high temperature structural materials.

Tungsten-rhenium alloy is a composite of two transition metals, tungsten (W) and rhenium (Re). This combination creates a material with unique properties, used in demanding environments. Typical chemical composition of this alloy:

• Tungsten (W): Approximately 95% to 99% by weight
• Rhenium (Re): Approximately 1% to 5% by weight

Main characteristics of the alloy W-Re:

• Heat resistance: W-Re alloy offers exceptional resistance to high temperatures, making it suitable for applications under extreme thermal conditions, such as gas turbine components and thermal shields in the aerospace industry.

• Corrosion resistance: Thanks to the presence of rhenium, which is known for its corrosion resistance, W-Re alloy provides increased protection against corrosive environments, thus extending its service life and reliability.


W-Re alloy applications:

• Aerospace industry: Rocket engine components, rocket nozzles, structural parts.
• Semiconductor Industry: Components for substrate media, electrical contacts.
• Chemical Industry: Chemical reactor equipment, corrosion resistant parts.
