Molybdenum Copper Heater Sinker

Molybdenum copper alloy is widely used as a heat sink material due to its high thermal conductivity. The preparation of molybdenum copper alloy mainly adopts the melt immersion method, using high-quality molybdenum powder and oxygen free copper powder, and applying isostatic pressing forming (high-temperature sintering copper infiltration). The structure is fine, the arc breaking performance is good, the conductivity is good, the thermal conductivity is good, and the thermal expansion is small.

Molybdenum copper heat sink materials are high-performance composite materials composed of two metal materials: tungsten, molybdenum, and copper. Tungsten copper and molybdenum copper heat sink materials have excellent properties such as high thermal conductivity, low coefficient of thermal expansion, high strength, high hardness, and high wear resistance, and are widely used in high-power semiconductor devices, electronic packaging, aerospace, military and other fields.

Molybdenum copper heat sink materials are usually prepared using powder metallurgy technology, and can be made into various shapes and sizes of materials, such as plates, bars, pipes, special-shaped parts, etc.

High Thermal Conductivity: Because of copper's high thermal conductivity, it enables the rapid transfer of heat from component parts of molybdenum copper heat sinks, thereby inhibiting the possibility of overheating.

High-Temperature Resistance: Molybdenum's high temperature capability ensures the proper functioning of the heat sink at dangerous temperatures.

Low Density & Lightweight: Molybdenum-copper alloys are less dense and lighter than tungsten-copper composites, which is advantageous for aerospace and other applications that need to reduce weight.

Excellent Sealing Performance: Molybdenum copper heat sinks possess strong airtightness providing good sealing face to high sealing limit areas.

Good Machinability: The material is versatile, which permits the fabrication of heat sinks into different configurations.

Adjustable Thermal Expansion: Altering the ratio of molybdenum to copper results in complete alignment of the alloy's thermal expansion with that of ceramics and semiconductors, therefore minimizing thermal strain.

Electronics: Used in high-performance computer chips and servers, molybdenum copper heat sinks are employed in microwave and millimeter wave electronics. They effectively manage heat to ensure stable operation of the components.

Aerospace: The critical weight in aerospace makes these heat sinks particularly useful due to their lightweight nature and ability to withstand high temperatures.

Automotive Industry: Molybdenum copper heat sinks are used to cool the batteries and motors of electric and hybrid vehicles.

Optoelectronics and Microwave Packaging: Used in optoelectronic and microwave packaging and in mounts of laser diodes and optical modules.

Renewable Energy: These components improve reliability and the overall efficiency of solar panels as well as wind turbines, helping systems maintain consistency.

FAQ

A: Yes, we are a factory but we generally use our trading company to handle the business abroad. It will be more convenient to receive the remittance and arrange the shipment.

What is the delivery method?

A: Generally, we send cargo by UPS, DHL or FedEx. Also, we can send by sea to seaport or by air to the closest airport.

Why is your product so cost-effective?

A: We cut out the middlemen in the end-to-end manufacturing process and we obtain raw material directly from its source.

Do you do spot quality inspection or full inspection?

A: 100% full inspection for sure. All unqualified products are discarded.

How do you ensure your lead time?

A: From material preparation to machining and finally to a full inspection. Every stage of production is strictly monitored and controlled to give you an accurate delivery time.

What is the MOQ of Molybdenum Copper Heater Sinker ?

A: Depends on quantity, generally, no MOQ limit.

What is a Molybdenum Copper Heater Sinker?

A Molybdenum Copper (MoCu) Heater Sinker is a high-performance thermal management component. It combines molybdenum's heat resistance with copper's excellent thermal conductivity for efficient heat dissipation.

What are the key advantages of MoCu Heater Sinkers?

High thermal conductivity (quick heat transfer)

Heat and corrosion resistance (stable in extreme conditions)

Lightweight (better than tungsten-copper alternatives)

Adjustable thermal expansion (matches ceramics/semiconductors)

Good machinability (easy to customize)

Where are MoCu Heater Sinkers commonly used?

Electronics: CPU/GPU cooling, power modules

Aerospace: Avionics, satellite systems

EV/Energy: Battery & motor cooling, renewable energy systems

Lasers/Optics: Laser diode heat dissipation

Why choose MoCu instead of pure copper or aluminum?

While copper and aluminum are cheaper, MoCu offers:

Higher temperature stability

Better strength and thermal fatigue resistance

Lower thermal expansion mismatch with critical materials

Can MoCu Heater Sinkers be customized?

Yes, they can be machined into various shapes and sizes. The Mo/Cu ratio can also be adjusted for specific thermal/mechanical needs.

How does MoCu compare to Tungsten Copper (WCu)?

MoCu is lighter and easier to machine than WCu, making it better for weight-sensitive applications (e.g., aerospace). WCu has higher density and better radiation shielding but is costlier.

Are MoCu Heater Sinkers reliable for long-term use?

Yes, they resist thermal fatigue, oxidation, and deformation even under high thermal cycling, ensuring long service life.
