Copper Tungsten Electrode Rod

Copper Tungsten Electrode Rod produced by our company have the characteristics of uniform organization, precise composition ratio and high processing accuracy. Our production of tungsten and copper rods can withstand high temperature, arc ablation, high strength,good thermal conductivity and conductivity, is a good sweating cooling material, our tungsten and copper rods can be widely used in aerospace, electric power, electronics, metallurgy, machinery, and other fields in the production.

The Copper Tungsten Electrode Rod is a composite electrode made of tungsten and copper. It combines the high melting point and strength of tungsten with the excellent conductivity and thermal conductivity of copper, offering superior overall performance. This material is typically produced through powder metallurgy. The process involves pressing and sintering tungsten powder into a porous preform, followed by copper infiltration to fill the pores. The composition ratio can be adjusted as needed, with common specifications including W70Cu30, W80Cu20, and W90Cu10.

Excellent Electrical and Thermal Conductivity:
The copper-tungsten electrode rod has conductivity and thermal conductivity between pure tungsten and pure copper. This allows it to quickly transfer current and heat, reducing heat buildup during processing.

High Melting Point and Strength:
Thanks to the tungsten content, the material has a high melting point and strength, ensuring stable performance even in high-temperature environments.

Strong Arc Erosion Resistance:
In electrical discharge machining, the copper-tungsten electrode resists arc erosion well, minimizing wear and extending service life.

Good Machinability:
Although tungsten is brittle, combining it with copper improves the material's workability, making it easier to machine.

Low and Adjustable Thermal Expansion:
The thermal expansion coefficient of copper-tungsten alloy is low and can be adjusted. This makes it compatible with semiconductors and other materials, suitable for high-precision machining.

EDM (Electrical Discharge Machining) Electrodes:
Copper-tungsten electrode rods are widely used in EDM, especially for machining hard materials like carbide and titanium alloys. They help improve precision and efficiency while reducing electrode wear.

Resistance Welding Electrodes:
In resistance welding, copper-tungsten electrodes can handle high current density. They also offer good conductivity and thermal shock resistance, making them ideal for high-precision welding.

Aerospace Applications:
These rods are used in rocket nozzles, missile components, and other aerospace parts. Their high melting point and strength ensure stable performance under extreme conditions.

Electronic Packaging & Heat Dissipation:
Since copper-tungsten alloy has a thermal expansion coefficient similar to semiconductors, it works well in electronic packaging and heat sinks, preventing thermal stress damage.

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 Copper Tungsten Electrode Rod?

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.
