Alloys (WRe,MoRe)
Rhenium can simultaneously improve the strength and ductility of tungsten, molybdenum and chromium. So people call this phenomenon as "rhenium effect."

Tungsten-Rhenium Alloy (WRe)
We add 3%, 5%, 25% and 26% of rhenium in tungsten to form tungsten rhenium alloy. Tungsten rhenium alloy has good electrical properties, ductility and workability. Its wire can be used as high temperature thermocouple and the cathode wire



Molybdenum-Rhenium Alloy (MoRe)
Molybdenum-rhenium alloy is formed by adding different contents of element rhenium into molybdenum. Molybdenum and rhenium are both refractory metals. By combining the two elements, molybdenum-rhenium alloy can have high-temperature physical properties of rhenium, and good mechanical properties of molybdenum, thus having born excellent performance. Its rolling deformation degree can be up to 90%. By adding 47.5% or 41% rhenium into molybdenum to form molybdenum-rhenium alloy (nominal composition 50%Mo+50%Re), its ductility, weldability and formability are greatly improved. Even at high temperatures, molybdenum-rhenium alloy can maintain its good ductility. Molybdenum-rhenium alloy is widely used in the electronics industry, the nuclear industry and the aerospace industry.

Application

Quartz continuous melting, industrial furnace industry, glass industry, semiconductor industry, electronic industry, metallurgy industry, and the field of nuclear power.

Titanium-zirconium-molybdenum alloys (TZM)

TZM is a commonly used alloy in molybdenum-based alloy, and it has a very excellent mechanical properties, especially at high temperature, its mechanical properties is better than that of pure molybdenum. It can be used in the high-temperature applications of severe mechanical loading, for example, it can be used for tools forging or as a rotating anode of X-ray tube. The recommended temperature of is from TZM 700 to 1400 ℃. 

Molybdenum-hafnium-carbon alloys (MHC)

MHC belongs to particulate-enhanced molybdenum alloy which contains hafnium and carbon. Since the ultra-fine carbides distribute evenly, this material can still exhibit its of the heat resistance and creep resistance at the temperature of 1550℃. The recommended maximum temperature is 150 ℃ higher than TZM. For example, MHC is used in the applications of metal forming applications. When it is used in the extrusion die, it can withstand extreme thermal and mechanical loads.

Molybdenum lanthanum alloys (MoLa)

Molybdenum is doped with bits of lanthanum oxide particles (0.3% or 0.7%), and then the so-called laminated-formed fibrous structure is formed. This particular microstructure can maintain stable even the temperature is up to 2000 ℃. And thus, even used in extreme conditions, the molybdenum-lanthanum oxide is also creep-resistant. We mainly process these alloys into high-temperature furnace components, such as twisted wire and other metal wire, sintering and annealing boat or evaporator coil. In the lighting industry, molybdenum-lanthanum oxide is also used as guard lines and feeder lines.

Molybdenum tungsten alloys (MoW)

By using the temperature properties and corrosion resistance of molybdenum material, the tungsten can be improved.

From MW20 in which the molybdenum accounts for 20% of the weight to MW50 in which the molybdenum accounts for 50% of the weight, we sell MoWs with different ingredients. They are mainly used in producing mixing tools required by the production of zinc and glass manufacturing industry.

In addition, we also use our MoW alloy to produce sputtering palladium coating materials for flat panel displays. The etching by using MoW to coatin is better, which is very valuable for manufacturing thin-film transistor.

Molybdenum rhenium alloys (MoRe)

After doped with bits of rhenium, the molybdenum has the ductility at room temperature. Molybdenum - rhenium (MoRe) is mainly used as thermocouple wire. And the standard ingredients of thermocouple wire are Mo5% Re and Mo41% Re, or for other situations in which ductility is important.

Molybdenum-copper alloys (MoCu)

Mo - Cu (MoCu) is a kind of composite material in which copper accounts for up to 30% of the weight. And this composite material comprises the copper with a high thermal conductivity the molybdenum with low coefficient of thermal expansion. Our MoCu is very suitable for the manufacture of the passive cooling element (radiator) in the electronic components.

Molybdenum zirconium oxide (MoZrO2)

Glass melting electrodes must withstand the ability of corrosion and high temperature. With the addition of zirconium oxide which accounts for 1.7% of the total weight, the molybdenum materials will then possess the useful features in the glass industry. When compared with the pure molybdenum, MoZrO2 has the better corrosion resistance of the molten glass, and the temperature stability is also better.

Molybdenum tantalum alloys (MoTa)

Our molybdenum sputtering palladium materials can be used to manufacture the functional thin layer of the flat display panel. Especially for a touch screen, a good corrosion resistance is an essential feature. Therefore, we add an alloy element----tantalum into the multi-purpose material molybdenum, in order to obtain high corrosion resistance, as well as to form a MoTa coating which is simple and fast to reconstruct.
