Molybdenum Copper Alloy, MoCu Alloy Sheet
Molybdenum copper (MoCu) alloy is a composite material of molybdenum and copper which has an adjustable thermal expansion coefficient and thermal conductivity. It has lower density yet higher CTE compared with copper tungsten. Therefore, molybdenum copper alloy is more suitable for aerospace and other fields.
Molybdenum copper alloy combines the advantages of copper and molybdenum, high strength, high specific gravity, high-temperature resistance, arc ablation resistance, good electrical conductivity and heating performance, and good processing performance.

Molybdenum Lanthanum (MoLa) Alloy Boat Tray
MoLa tray is mainly used for metals or sintering and annealing of the non-metals under reducing atmosphere. They are applied to boat sintering of powder products such as delicately sintered ceramics. Under certain temperature, molybdenum lanthanum alloy is easier to be re-crystallized which means it is not easy to deform and has a longer service life. Molybdenum lanthanum tray is exquisitely made by high density of molybdenum, lanthanum plates and excellent machining techniques. Normally molybdenum lanthanum tray is processed by riveting and welding.

Molybdenum Lanthanum (Mo-La) Alloy Wire
Molybdenum Lanthanum (Mo-La) is an alloy made by adding Lanthanum Oxide into molybdenum. Molybdenum Lanthanum Wire has the properties of higher temperature of recrystallization, better ductility, and excellent wear-resistant. Molybdenum (Mo) is gray-metallic and has the third-highest melting point of any element next to tungsten and tantalum. High-temperature molybdenum wires, also called Mo-La alloy wires, are for high-temperature structural materials (printing pins, nuts, and screws), halogen lamp holders, high-temp furnace heating elements, and leads for quartz and Hi-temp ceramic materials, and so on.

Molybdenum Lanthanum (MoLa) Alloy Sheets
MoLa alloys have great formability at all grade levels when compared to pure molybdenum in the same condition. Pure molybdenum recrystallizes at approximately 1200 °C and becomes very brittle with less than 1% elongation, which makes it not formable in this condition.
MoLa alloys in plate and sheet forms perform better than pure molybdenum and TZM for high temperature applications. That is above 1100 °C for molybdenum and above 1500 °C for TZM. The maximum advisable temperature for MoLa is 1900 °C, due to the release of lanthana particles from the surface at higher than 1900 °C temperature.
The “best value” MoLa alloy is the one containing 0.6 wt % lanthana. It exhibits the best combination of properties. Low lanthana MoLa alloy is an equivalent substitute for pure Mo in the temperature range of 1100 °C – 1900 °C. The advantages of high lanthana MoLa, like superior creep resistance, are only realized, if the material is recrystallized prior to use at high temperatures.

High Temperature Molybdenum Lanthanum (MoLa) Alloy Rod
Molybdenum Lanthanum alloy (Mo-La alloy) is an oxide dispersion strengthened alloy. Molybdenum Lanthanum (Mo-La) alloy is composed by adding lanthanum oxide in molybdenum. Molybdenum Lanthanum alloy (Mo-La alloy) is also called rare earth molybdenum or La2O3 doped molybdenum or high temperature molybdenum.
Molybdenum Lanthanum (Mo-La) Alloy has the properties of higher temperature of recrystallization, better ductility, and excellent wear-resistant. Recrystallizing temperature of Mo-La alloy is higher than 1,500 degrees Celsius.
Molybdenum-lanthana (MoLa) alloys are one type of ODS molybdenum-containing molybdenum and a very fine array of lanthanum trioxide particles. Small quantities of lanthanum oxide particles (0.3 or 0.7 percent) give the molybdenum a so-called stacked fiber structure. This special microstructure is stable at up to 2000°C.

TZM Alloy Nozzle Tips for Hot Runner Systems
Molybdenum TZM – (Titanium-Zirconium-Molybdenum) alloy
The hot runner system is an assembly of heated components used in plastic injection molds that inject molten plastic into the cavities of the mold, to obtain high quality plastic products. And it is usually make of nozzle, temperature controller, manifold and other parts.
Titanium zirconium molybdenum (TZM) hot runner nozzle with high temperature resistance, high strength, good corrosion resistance and other excellent properties, are widely used in all kinds of hot runner nozzle production. TZM nozzle is an important part of the hot runner system, according to the nozzle in the form shape it can be divided into two main type, open gate and valve gate.

High Quality TZM Molybdenum Alloy Rod
TZM Molybdenum is an alloy of 0.50% Titanium, 0.08% Zirconium, and 0.02% Carbon with the balance Molybdenum. TZM Molybdenum 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 2000F.
TZM Molybdenum has a higher recrystallization temperature, higher strength, hardness, good ductility at room temperature, and elevated temperatures than unalloyed Molybdenum. TZM offers twice the strength of pure molybdenum at temperatures over 1300C. The recrystallization temperature of TZM is approximately 250°C, higher than molybdenum, and it offers better weldability. In addition, TZM exhibits good thermal conductivity, low vapor pressure, and good corrosion resistance.
Zhaolixin developed low-oxygen TZM alloy, where the oxygen content can be lowered to less than 50ppm. With low oxygen content and small, well-dispersed particles that have remarkable strengthening effects. Our low oxygen TZM alloy has excellent creep resistance, higher recrystallization temperature, and better high-temperature strength.

High Quality Molybdenum Alloy Products TZM Alloy Plate
TZM (titanium, zirconium, molybdenum) Alloy Plate
Molybdenum’s prime alloy is TZM. This alloy contains 99.2% min. To 99.5% max. Of Mo, 0.50% Ti and 0.08% Zr with a trace of C for carbide formations. TZM offers twice the strength of pure moly at temperatures over 1300′C. The recrystallization temperature of TZM is approximately 250′C higher than moly and it offers better weldability.
The finer grain structure of TZM and the formation of TiC and ZrC in the grain boundaries of the moly inhibit grain growth and the related failure of the base metal as a result of fractures along the grain boundaries. This also gives it better properties for welding. TZM costs approximately 25% more than pure molybdenum and costs only about 5-10% more to machine. For high strength applications such as rocket nozzles, furnace structural components, and forging dies, it can be well worth the cost differential.
