CuW Alloy

Product Description

What Tungsten Cooper alloy is?

Tungsten Copper Alloy (CuW Alloy) is a composite material made from tungsten and copper. It is produced using powder metallurgy techniques, combining the excellent electrical and thermal conductivity of copper with the high-temperature strength and hardness of tungsten. This results in a material that offers superior performance in demanding environments.

 

What can tungsten copper alloy be used for?

Tungsten Copper Alloy is widely used in various industries due to its unique properties. Key applications include:

Vacuum Contact Materials: For circuit breakers and switches.

Electrode Materials: For resistance welding, EDM, and plasma cutting.

Electronic Packaging Materials: For heat dissipation in high-power devices.

Aerospace and Defense: For rocket nozzles, missile components, and radiation shielding.

It is extensively utilized in industries such as machinery, power, electronics, metallurgy, and aerospace.

Composition

• Tungsten (W): Typically ranges from 50% to 90% by weight, depending on the application.
• Copper (Cu): Makes up the remaining percentage, providing conductivity and ductility.

 

Common Grades

• CuW50: 50% tungsten, 50% copper.
• CuW75: 75% tungsten, 25% copper.
• CuW80: 80% tungsten, 20% copper.
• CuW90: 90% tungsten, 10% copper.

 

Properties

• High Thermal Conductivity: Copper provides excellent heat dissipation, making CuW alloys suitable for thermal management applications.
• High Electrical Conductivity: Copper ensures efficient electrical performance.
• High Melting Point: Tungsten contributes a melting point of up to 3410°C, making CuW alloys resistant to high temperatures.
• Wear Resistance: Tungsten provides exceptional hardness and durability, reducing wear in high-stress environments.
• Low Thermal Expansion: CuW alloys exhibit low thermal expansion, making them stable under thermal cycling.
• Arc Erosion Resistance: Ideal for electrical contacts and electrodes due to resistance to arcing and welding.

 

Manufacturing Processes

• Powder Metallurgy

Tungsten and copper powders are mixed, pressed, and sintered to form the alloy.

• Infiltration

Tungsten powder is pressed into a mold and infiltrated with molten copper.

• Hot Isostatic Pressing (HIP)

Used to achieve high-density, uniform structures.
