Description of MoCu Alloy Plate

MoCu Alloy Plate is a high-performance material made of molybdenum (Mo) and copper (Cu), usually supplied in plate form. Its composition can be adjusted based on needs, with molybdenum typically ranging from 50% to 85% and copper from 15% to 50%. The alloy is usually produced by infiltrating copper into porous sintered molybdenum. This method ensures strong bonding and good performance.

MoCu alloy plates are widely used in aerospace, electronic cooling, industrial furnace parts, vacuum equipment, and electrical switches. They offer excellent thermal performance, high-temperature strength, and electromagnetic compatibility. These properties make them suitable for various demanding working conditions. As a result, MoCu alloy plates are a top choice for high-performance materials.

features of MoCu Alloy Plate

Exemplary Thermal Properties:

MoCu alloy possesses substantially high thermal conductivity. For instance, Mo80Cu20 can achieve a thermal conductivity range of 170-190 W/m·K. It also has a low thermal expansion coefficient, which makes it suitable for many materials. This facilitates great applicability in high-performance thermal management.

Excellent Strength High-Temperature Performance:

In terms of alloy strength, oxidation resistance, and high-temperature performance, MoCu alloy performs outstandingly, maintaining a melting range of 1800°C to 2200°C. Furthermore, the MoCu alloy's surface builds a protective oxide layer that prevents further oxidation, increasing durability.

Enhanced Mechanical Strength:

In comparison to other alloys, MoCu offers outstanding mechanical parameters. It contains exceptional hardness and tensile strength, reaching up to 420 MPa for Mo70Cu30. Moreover, MoCu has a significantly lower density than tungsten-copper alloys, making it advantageous in applications where weight is a crucial factor.

Electromagnetic Compatibility (EMC):

MoCu alloy is non-magnetic and offers outstanding electromagnetic interference (EMI) shielding, and, as a result, enhances its domain of applicability to electronic devices that require high EMC.

Ease of Machining:

Many metal composites are hard to machine. In comparison, MoCu alloy is subjected to fewer machining restrictions and is easier to process. For instance, stamping and forming are accomplished with greater ease.

Applications of MoCu Alloy Plate

Aerospace Applications:

MoCu alloy plates are utilised in the construction of rockets and missiles at highly elevated temperatures, in components such as nozzles and heat shields. The close bounds of thermal conductivity, excellent high temperature strength and MoCu's exceptional properties make it a choice suitable for high-performance aerospace applications.

Electronics Industry:

In a broad range of electronic devices, MoCu alloy is a very good conductor and efficiently fulfils the role of a heat sink and thermal spreader. Further, the reduction of thermal stress allows for effective conduction and dissipation of heat while the low expansion coefficient of MoCu assists in tapering thermal stress.

Industrial Furnaces & High Temperature Tools:

Furnace parts and high-temperature tools are best equipped with MoCu alloy due to its extreme resistance to high temperatures along with optimal preservation of mechanical properties.

Vacuum Technology:

Owing to the low gas content and remarkable performance in vacuum conditions, MoCu alloy proves to be very effective for use in components designed for vacuum environments.

Electronics Industry:

Because of the demanding requirements on their conductivity and wear resistance, MoCu alloy is used in switch contacts of medium and high voltage appliances.
