Molybdenum Foil/Strip/Ribbon Production Process

Molybdenum foil, strip, and ribbon are made of high-purity molybdenum ingots through hot rolling, cold rolling, and annealing to achieve the desired thickness, strength, and ductility. Additional treatments such as polishing and chemical etching may be applied to meet specific application requirements. Here is the typical production process:

Raw Material Selection: Molybdenum Ingot or powder is selected based on purity and quality requirements.
Melting and Casting: Molybdenum is melted in a vacuum or inert gas atmosphere and cast into ingots.
Hot Rolling: The ingot is heated and passed through rollers to reduce the thickness and achieve the desired shape.
Cold Rolling: Further thickness reduction is achieved at room temperature, improving the material’s surface finish and mechanical properties.
Annealing: The material is heat-treated to relieve internal stresses and improve ductility.
Pickling and Polishing: The surface is cleaned using chemical treatments to remove oxides and improve appearance.
Final Cutting: The material is cut into foil, strip, or ribbon forms, depending on the specific application requirements.

Molybdenum Foil/Strip/Ribbon Applications

Electronics: As a highly conductive material, molybdenum foil/strips/ribbon is widely used in connectors and circuit boards for electronic devices, replacing traditional copper-based materials.
Energy: Molybdenum foil/strip/ribbon is used to manufacture electrodes for solar cells, improving the efficiency of solar cells.
Aerospace: Due to its high density, high strength, and high toughness, molybdenum foil/strip/ribbon is used in a wide range of applications such as aircraft structural parts and satellite components.

Molybdenum Foil/Strip/Ribbon Packaging

The Molybdenum Foil/Strip/Ribbon is carefully placed in wooden cases or cartons with additional support from soft materials to prevent any shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
