Molybdenum wire and molybdenum rods
Molybdenum wire and molybdenum rod, with their outstanding high-temperature performance, have become the core heating elements of vacuum high-temperature furnaces and special heat treatment equipment. Molybdenum wire and molybdenum rods have a melting point as high as 2620°C, and can operate at temperatures ranging from 1600 to 2200° C. In the short term, they can even withstand extreme high temperatures of 2400°C, far exceeding traditional materials such as nickel-chromium alloys. The low coefficient of thermal expansion enables it to effectively resist thermal cycling stress, while the high resistivity enables efficient direct heating. In addition, the extremely low evaporation rate in a vacuum environment avoids contamination of the materials inside the furnace, providing a stable guarantee for high-temperature processes.
In a variety of industrial applications, molybdenum wires and molybdenum rods play an irreplaceable role. They are widely used in high-temperature sintering of advanced ceramics and hard alloys, single crystal growth of sapphire and semiconductor materials, as well as annealing of refractory metals and diffusion welding of high-temperature alloys and other metal heat treatment processes. Whether it is the 1600-2000°C required for ceramic densification or the 2100°C high-temperature environment for semiconductor crystal growth, molybdenum-based heating elements can operate stably, ensuring the precise implementation of the process.
According to different application scenarios, molybdenum wires and molybdenum rods are designed in various structural forms. Molybdenum wire is often made into spiral coils or wavy shapes and is suitable for uniform heating in small furnaces. Molybdenum rods are available in various shapes such as straight rods and U-shaped ones, meeting the high power demands of large industrial furnaces. Molybdenum sheet heating elements can achieve rapid radiant heating. To ensure its performance, the components need to operate in a vacuum or inert atmosphere and be precisely temperature-controlled by a power supply. Facing technical challenges such as high-temperature creep, surface evaporation and cold-end corrosion, through improvement schemes such as alloy doping, surface coating and structural optimization, the service life and reliability of the components have been significantly enhanced.
Mosten Alloy can produce molybdenum sheet, molybdenum block, molybdenum foil, molybdenum rod, molybdenum wire, molybdenum processing workpiece according to customer demand.
