High Purity Molybdenum Foils

High-purity molybdenum foil is a thin sheet material made from high-purity molybdenum, typically with a purity of 99.9% or higher. The production process includes melting, rolling, and annealing to ensure material purity and performance. With precision data of 99.95% purity, our high-quality molybdenum foils are our excellent flagship products. The minimum thickness of the thin molybdenum foils we supply is 0.05mm, and the width is 610mm. The longest molybdenum foil is 3000mm.

Molybdenum foils are used to heat electronic vacuum furnaces and insulated screens, while molybdenum circular foils are used to produce molybdenum sheets and power semiconductors, and are raw materials for vacuum light sources. The molybdenum sheet has a bright and smooth surface and good reprocessing characteristics.

Raw material selection: High-purity molybdenum foil is usually made of high-purity molybdenum powder, with a purity of more than 99.95%.
Preparation method: Powder metallurgy, rolling, or chemical vapor deposition (CVD) and other processes are used. Powder metallurgy prepares molybdenum billets by pressing and sintering, and then obtains thin foils through multiple rolling. CVD deposits a molybdenum layer on a substrate through chemical reactions to form a thin film.
Post-processing: includes annealing to improve mechanical properties and surface quality, as well as cleaning to remove surface impurities.

High Purity: High-purity molybdenum foil typically has a purity of 99.9% or even higher. This high purity ensures excellent performance in applications sensitive to impurities, such as semiconductors and electronics.

Excellent Thermal Properties: Molybdenum foil has a high melting point (about 2620°C) and high thermal conductivity, allowing efficient heat transfer. Its low thermal expansion coefficient matches well with many semiconductor materials, making it ideal for thermal management applications.

Good Mechanical Properties: Molybdenum foil is strong and ductile, maintaining stability even under high temperatures and harsh conditions. After annealing, it becomes even more flexible and easier to process.

Corrosion Resistance: Molybdenum foil resists many chemicals, ensuring a long service life in industrial and chemical environments.

Thin and Flexible: Molybdenum foil can be made extremely thin while remaining flexible. This allows easy cutting, bending, and welding, making it suitable for complex shapes and custom sizes.

Electronics Industry: Molybdenum foil is widely used in electronic components, such as circuit boards, connectors, and heat sinks for semiconductor devices. Its high electrical and thermal conductivity make it an ideal material for electronics.

Energy Sector: In solar cells, molybdenum foil serves as an electrode material, helping to improve efficiency. It is also used in fuel cells and energy storage devices.

Aerospace Industry: Due to its high strength and heat resistance, molybdenum foil is suitable for structural parts and satellite components in aerospace applications.

Lighting Industry: Molybdenum foil is commonly used in lamp seals, such as UV curing lamps and quartz infrared heating lamps. Its thermal expansion coefficient is similar to glass, preventing seal cracks effectively.

Chemical & Industrial Use: Molybdenum foil can be used to make corrosion-resistant containers and reactors, suitable for handling various chemicals.

Medical Equipment: In medical X-ray systems, molybdenum foil is used as a component in high-energy X-ray tubes. Its high density and heat resistance allow it to withstand high power density.

Purity detection: The purity of molybdenum foil is detected by spectral analysis and other means to ensure that there are no impurities.
Thickness uniformity: Use a high-precision thickness gauge to detect the thickness uniformity of molybdenum foil to ensure that it meets the specification requirements.
Surface quality: Check whether there are scratches, cracks, oxidation and other defects on the surface to ensure that the surface is smooth.
