Machining Copper Tungsten Plate

Tungsten copper sheet is widely used in EDM electrode,Our tungsten copper alloy sheets are manufactured using the vacuum infiltration method. The product has excellent physical and mechanical properties, and has excellent anti-burning ability. our tungsten-copper alloy plate complies with ASTM B702, Class 10, Class11, Class12, GB/T8320- 2003 standards.

Copper-tungsten plates are widely used in aerospace, electronics, medical, and automotive industries. In aerospace, they are used for high-temperature components like rocket nozzles and heat shields. In electronics, their thermal conductivity makes them ideal for heat sinks and electrodes in high-power devices. For medical equipment, they are applied in X-ray tubes and radiation shielding. In automotive manufacturing, they help produce complex parts and molds. Additionally, their wear resistance and high-temperature stability make them a preferred material for the mold industry.
 

Thermal Properties:
Copper-tungsten plates have excellent thermal conductivity, allowing them to efficiently transfer and dissipate heat. This is crucial in high-heat applications. Additionally, they have a low thermal expansion coefficient, meaning they maintain dimensional stability even under temperature changes.

Mechanical Properties:
This material offers high strength and good fatigue resistance, making it reliable in dynamic or high-vibration environments. Moreover, its hardness and wear resistance are high, enabling it to withstand abrasion and corrosion.

Electrical Properties:
The electrical conductivity of copper-tungsten plates varies with tungsten content, but overall, they still provide good conductivity. This makes them suitable for applications requiring high current-carrying capacity.

Machinability:
Although the hardness and wear resistance of copper-tungsten plates pose challenges in machining, high-precision processing is still achievable. By using suitable tools (such as carbide or diamond cutters) and optimizing machining parameters, good results can be obtained.

Aerospace:
Copper-tungsten plates are used to make rocket nozzles and heat shields. These parts must maintain strength and performance under extreme temperatures.

Electronics Industry:
In high-power electronic devices, copper-tungsten plates work as heat sinks. They help manage heat and keep the equipment running smoothly. They are also used in electrical contacts and resistance welding electrodes.

Medical Equipment:
Copper-tungsten plates are used in X-ray tubes and radiation shielding. Their high density and radiation absorption make them ideal for these applications.

Automotive Manufacturing:
In car production, copper-tungsten plates help create precise and complex parts and molds.

Molds & Tooling:
Thanks to their wear resistance and heat stability, copper-tungsten plates are great for molds in plastic injection molding and metal casting.

FAQ

Are you a factory or manufacturer?

A: Yes, we are a factory but generally, we use our trading company to handle the business abroad. It will be 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. Rather than obtaining semi-finished goods from other suppliers, we obtain our raw material of APT powder directly from its source.

Do you do spot quality inspection or full inspection?

A: 100% full inspection. Inspectors will check the finished product individually, to ensure they adhere to all parameters. All unqualified products are discarded.

How do you ensure your lead time?

A: We have an efficient Order Management System, 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 Machining Copper Tungsten Plate?

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

How to pay for it?

A: A bank transfer (T/T) will be acceptable.

What is the delivery time?

A: around 7-20 days which depends on the quantity and production.

What is kind of the package?

A: Generally, we use a carton case or plywood case with protective material inside to ensure the save of cargo

What is the lead time?

A: from order placed to cargo receiving will take around 10-25 days.

What tools are best for machining copper tungsten?

A: Carbide or diamond-coated tools are recommended due to their hardness and wear resistance. High-speed steel (HSS) tools wear out quickly and are less efficient.

What machining methods work for copper tungsten?

A: Common methods include:

Turning & Milling (using rigid setups and sharp carbide tools)

Grinding (for fine finishes and tight tolerances)

EDM (Electrical Discharge Machining) (for complex shapes without tool wear)

What are the key challenges when machining copper tungsten?

A:

Tool wear (due to material hardness)

Heat generation (requires proper cooling)

Brittleness (risk of chipping if cutting forces are too high)

How to improve machining efficiency?

A:

Use sharp, high-quality carbide or diamond tools

Apply coolant to reduce heat and extend tool life

Optimize cutting speeds & feed rates (slower speeds than for copper)

Secure the workpiece firmly to prevent vibration

Can copper tungsten be polished after machining?

A: Yes, it can be polished using diamond abrasives or fine grinding for a smooth finish.

What safety precautions should be taken?

A:

Wear safety goggles & gloves (tungsten dust can be abrasive)

Use proper ventilation (especially during grinding)

Handle sharp edges carefully (machined parts may have burrs)
