Product Overview
Molybdenum foil is manufactured from high-purity molybdenum (Mo) or molybdenum alloys through cold rolling, hot rolling, and annealing processes, producing thin metal sheets with thicknesses of 0.01-0.1 mm (some specifications can be thinner). Characterized by high melting point, low thermal expansion coefficient, excellent electrical/thermal conductivity, and outstanding corrosion resistance, it is widely used in demanding applications including high-temperature, vacuum, electronics, and aerospace environments. Common grades include Mo1, MoLa, and TZM with purity ≥99.95%.

Key Advantages
Extremely High Melting Point: 2623°C (significantly higher than aluminum/copper), suitable for continuous operation at 1800-2200°C
Low Thermal Expansion Coefficient: ~5×10⁻⁶ K⁻¹ ensures dimensional stability during thermal cycling
Excellent Thermal/Electrical Conductivity: Thermal conductivity ~138 W·m⁻¹·K⁻¹, resistivity ~5.3 µΩ·cm, meeting high-power heat dissipation requirements
High Elastic Modulus & Tensile Strength: Elastic modulus ~330 GPa, tensile strength >600 MPa, maintaining mechanical integrity in thin films
Corrosion & Oxidation Resistance: Virtually non-corrosive in acidic/alkaline and chloride environments, suitable for chemical and nuclear applications
Superior Processability: Cold-rollable to <0.008 mm, supporting precision processing including laser cutting, punching, and bending
High Density: ~10.2 g·cm⁻³ provides excellent shielding and structural strength
Selection & Usage Guidelines
Temperature Requirements: For operating temperatures ≥1800°C, recommend high-purity molybdenum foil (≥99.99%) with annealing treatment to reduce internal stress
Mechanical Strength: For high tensile strength applications (e.g., aerospace structures), select TZM (Mo-Ta-Zr-Mg) alloy foil for enhanced strength and toughness
Thermal/Electrical Conductivity: For electronic packaging requiring high thermal dissipation, choose high-purity molybdenum foil (0.025-0.05 mm thickness) with polished surface for optimal thermal conduction
Corrosive Environments: For strong acid/alkali or chloride environments, recommend alkaline-acid cleaned molybdenum foil with protective coatings
Custom Sizing: For special widths or shapes (circular, irregular), coordinate laser cutting or punching processing with supplier in advance
