Products Description
In the field of semiconductor manufacturing and high-end industrial furnaces, many pieces of equipment are facing severe high-temperature tests. Materials often begin to experience grain growth, strength attenuation, or creep deformation above 1200 °C, resulting in equipment shutdown for maintenance, and even affecting the safety and efficiency of the entire production chain. At this time, a special pipe strengthened by rare earths, a MoLa alloy pipe, is becoming the preferred solution for more and more engineers.
The MoLa alloy tube is not a simple upgrade of the ordinary molybdenum tube. It forms an oxide dispersion strengthened (ODS) structure by uniformly dispersing lanthanum oxide (La₂O₃) particles in a high-purity molybdenum matrix. This microscopic design makes the material's "skeleton" stable under extreme conditions, which not only inherits the advantages of molybdenum's high melting point and thermal conductivity, but also greatly makes up for the shortcomings of pure molybdenum's easy embrittlement and low recrystallization temperature at high temperatures.
We position it as a high-end high-temperature structural pipe: suitable for those scenarios with extremely high requirements for dimensional stability, creep resistance, and service life. It is not a universal material, but in a vacuum or inert atmosphere from more than 1,000 degrees to close to 1600 degrees Celsius, its performance often surpasses that of TZM alloy and pure molybdenum, especially in thermal field systems that require continuous operation.
Ultra-high recrystallization temperature:
can reach more than 1500-1600 ℃, much higher than 1000-1200 ℃ of pure molybdenum. This means that the grain is not easy to coarse at high temperatures, and the material has good mechanical properties and will not suddenly;
Excellent creep resistance:
When withstanding high temperature stress for a long time, the deformation is extremely small, the service life can be extended by 2-3 times or even more than ordinary molybdenum materials, and the cost of replacement and shutdown is high;
Better room temperature and high temperature ductility:
improved machinability after doping, room temperature brittleness, convenient for subsequent welding, bending, and precision machining, and more reliable welds.
These characteristics are not laboratory data, but reliable performance that has been verified by the actual industry. We can provide customized pipes with different wall thicknesses, diameters, and lengths according to the content of La₂O₃(usually 0.3%-1.2%) of customers' needs, and the surface can be finished or polished.
High-temperature vacuum furnace and heat treatment equipment
Core components such as heating elements, heat insulation screens, support frames, and sintering boats. In the crystal growth furnace and vacuum annealing furnace, MoLa Alloy tubes can fluctuate in shape and strength for a long time, and the thermal field can fluctuate, so as to improve the yield of products. Many customers reported that the maintenance cycle was significantly extended after use.
Glass and optical fiber manufacturing
As an electrode, stirrer bar, or high-temperature vessel component, it is resistant to molten glass corrosion and has a stable size, especially suitable for high temperatures in continuous production.
Electronics and Semiconductor Industry
High temperature components for X-ray tubes, cathode ray tube assemblies, power semiconductor heating elements, and microwave magnetrons. Low vapor pressure and high purity ensure no contamination of the process.
Why Choose Our MoLa Alloy Tubes?
We have been deeply involved in refractory metals for many years, and we adopt powder metallurgy combined with precision processing technology to ensure the uniform distribution of La₂O₃ particles without obvious accumulation, and control the consistency of performance from the source. Each batch of products has undergone strict density, mechanical properties, and non-destructive testing to control every detail.
Compared with imported similar products, we have more advantages in delivery cycle and cost performance, and can quickly respond to customization needs, whether it is ultra-long thin-walled tubes or special-shaped specifications, solutions can be discussed.
Every stable operation at high temperature is an affirmation of material selection. If your equipment is facing high temperature deformation, short life, or maintenance troubles, you may wish to consider MoLa alloy pipes. It may be the key upgrade that makes the system more reliable and efficient.
