Mo1 molybdenum ring
Products Features
Mo1 molybdenum ring is a ring precision component made of high-purity molybdenum metal, the grade is Mo1, and the molybdenum content is ≥ 99. 95%. As a representative of refractory metal materials, molybdenum rings play an irreplaceable role in many high-tech industrial fields by virtue of their excellent physical and chemical properties. Execute the standard GB/T 3876-2007, density ≥ 10. 2 g/cm ³, melting point up to 2620 °C. These characteristics make it a material choice for extreme work.
Extreme high temperature performance
The melting point of molybdenum is as high as 2620 °C, far exceeding most common metal materials. At a high temperature of 1000 °C, the tensile strength of the Mo1 molybdenum ring can still be about 200 MPa, showing excellent mechanical strength and creep resistance. Even under the extremely high temperature conditions of 1100-1700 ℃, it can still have good structural integrity and is the choice of thermal field materials for high temperature furnaces.
low heat coefficient
The thermal coefficient of molybdenum is only 4.9 × 10 °C/°C, about 1/3 of that of silicon materials, which is close to that of ceramics, glass, and other materials. When the temperature fluctuates ± 50 ℃, the radial deformation of the molybdenum ring with a diameter of 200mm does not exceed 0.05 mm. This characteristic makes it effective for stress cracking problems caused by temperature changes in dissimilar material connection scenarios.
Excellent chemical stability
Molybdenum has excellent chemical inertia at high temperature, and its reactivity with alumina melt is lower than that of silicon material, which can avoid crystal defects caused by the diffusion of impurity elements into the melt. At the same time, it has good corrosion resistance and can resist the erosion of corrosive gases such as sulfur. The molybdenum content of the Mo1 molybdenum ring is stably controlled above 99.95%. Through advanced powder metallurgy and pressure processing technology, the internal structure of the product is ensured to be uniform, free of pores and inclusions. Dimensional accuracy can be controlled within ± 0.1 mm, surface roughness Ra ≤ 3.2 μm, and precision industrial application requirements.

Application Advantages
Semiconductor and Electronics Industry
In the sapphire crystal growth furnace, the Mo1 molybdenum ring is used as the core support structure, which can effectively prevent the overflow of solid raw materials and increase the crystal yield to more than 92%. In the vacuum cavity connection components of semiconductor manufacturing equipment, the impurity content must be controlled below 50ppm to ensure the yield of semiconductor products. At the same time, it is also used in plasma coating sputtering targets, chip heat sinks, and other fields.
High-temperature industrial furnace
As a key component of the vacuum furnace body, high temperature resistant material rack, burning boat, thermocouple protection tube and so on, Mo1 molybdenum ring plays an important role in high temperature industrial furnace. Its excellent high temperature stability and mechanical strength enable it to withstand repeated thermal cycles.
Photovoltaic industry
In the vacuum coating equipment of crystalline silicon solar cells, the Mo1 molybdenum ring is used to carry and transmit the metal evaporation source, so that the metal film can be accurately deposited on the surface of the silicon wafer, and the photoelectric conversion efficiency of the solar cell can be improved.
Product Advantage and Value
1. Excellent service life
The single service life of the Mo1 molybdenum ring module can reach 50-80 furnaces, which is 3-5 times that of silicon crystal material. In new applications such as geothermal generators, after 18,000 hours of continuous operation at 450 °C and 30MPa, the sealing performance is still above 92% of the initial value.
2. Precise manufacturing process
It is made by hydrogen reduction, isostatic pressing, high temperature sintering, and multi-pass warm/cold rolling. After being processed with more than 60% deformation, the internal structure is dense, the tensile strength is high, and the high-temperature creep resistance is excellent.
3. Full-form supply capacity
Provide plate/foil (thickness 0.025 mm-50mm), bar (diameter Φ3mm-Φ100mm), wire (diameter from Φ0.05 mm) and special-shaped parts for precision CNC machining according to customer drawings, different industry needs. Strictly follow the GB/T 3876 standard for production, and each step of the production process and finished products have passed the inspection of the QC department to ensure that the products are stable and reliable.
