Features

High Electrical and Thermal Conductivity:
Tungsten-copper alloy has excellent electrical and thermal conductivity, allowing efficient current transfer and heat dissipation. For example, a 70/30 tungsten-copper alloy has a thermal conductivity of up to 200 W/m·K.

High Melting Point and Density:
The addition of tungsten gives the alloy a high melting point, making it suitable for extreme temperatures. Its high density also ensures strong performance in high-stress electrical applications.

Good Mechanical Properties:
The alloy has high hardness and elastic modulus, providing strong mechanical strength and wear resistance. For example, a 70/30 tungsten-copper alloy has a hardness of 85-98 HRB.

Low Thermal Expansion Coefficient:
Tungsten-copper alloy has a low thermal expansion coefficient, which helps maintain dimensional stability and reduces deformation under different thermal conditions.

Excellent Arc Erosion Resistance:
Under electric arc conditions, the material shows minimal wear, extending the service life of electrical contacts.

Good Machinability:
Despite its high hardness and strength, tungsten-copper alloy is relatively easy to machine, allowing the production of complex and precise components.

Applications

Electrical Applications:
Tungsten-copper alloy is widely used in electrical switchgear, such as high and medium-voltage circuit breakers, relays, and switch contacts. Its high conductivity and arc erosion resistance make it an ideal electrode material.

Electronics Industry:
In electronic devices, tungsten-copper alloy is used to make heat sinks and thermal spreaders for efficient heat dissipation. For example, in high-power semiconductor devices, tungsten-copper heat sinks help manage heat effectively.

Aerospace and Defense:
Tungsten-copper alloy is used in spacecraft thermal management components, such as satellite heat shields and missile nose cones, because it can withstand extreme temperatures and mechanical stress.

Medical Equipment:
Tungsten-copper alloy is used in X-ray tube anodes and other critical parts due to its high thermal conductivity and heat resistance.

Industrial Uses:
Tungsten-copper alloy is also used in electroplating electrodes and special cutting tools because of its good conductivity and wear resistance.

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 ASTM B702 Wcu Alloy Copper Tungsten Bar?

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.
