Description of Molybdenum Copper Alloy Foil Sheet

Molybdenum copper alloy is a composite material composed of molybdenum and copper, which is more suitable for processing and mass production than tungsten copper.

Molybdenum Copper Alloy Foil Sheet is a very popular vacuum electrical contact material in China. It combines the excellent properties of molybdenum and copper, such as excellent high-temperature stability, strong electrical and thermal conductivity, good processability, and strong corrosion resistance.

Molybdenum-copper alloy has both good strength and certain plasticity at room temperature and medium temperature. When the temperature exceeds the melting point of copper, the copper will liquefy and evaporate, absorb heat, and play a cooling role. This property can be used as high-temperature materials for special purposes, such as electrical contact materials under high-temperature arc action.

Molybdenum Copper Alloy Foil Sheet can also be used as conductive and heat-dissipating materials for high-power devices such as integrated circuits, high and medium voltage switches or circuit breakers, microwave devices, and electric vacuum devices.

Features of Molybdenum Copper Alloy Foil Sheet

1. Ultra-Thin and Lightweight
Thickness: 0.02-0.1mm (thinnest down to 10μm), density: 10-12 g/cm³ (30% lighter than tungsten copper).

Flexible and Bendable: Suitable for curved heat dissipation or flexible electronic devices (requires annealing).

2. Excellent Thermal Management
Thermal conductivity: 160-220 W/(m·K): Nearly equal to pure copper, enabling rapid heat dissipation (e.g., reducing chip junction temperature by 20%).

Coefficient of Thermal Expansion (CTE): 5.5-8.5×10⁻⁶/°C: Perfectly matches semiconductor materials (Si, GaAs), reducing thermal stress failure.

3. Electrical and Electromagnetic Properties
Conductivity: 30%-60% IACS: Suitable for current-carrying components (such as ground planes in high-frequency circuits).

Non-Magnetic: Compatible with precision equipment such as MRI and quantum computing.

4. High-Temperature Resistance and Stability
Short-term temperature resistance ≤1000°C (before copper phase melts), long-term stability ≤600°C (anti-oxidation coating required).

The molybdenum skeleton maintains high-temperature strength and prevents thermal deformation.
