What Is Tungsten Copper Rod?
Tungsten Copper Rod is a metal matrix composite combining tungsten and copper.
The two materials contribute different characteristics. Tungsten provides high hardness, high-temperature capability and resistance to arc erosion, while copper contributes electrical and thermal conductivity.
The resulting WCu composite is therefore useful in applications where one material alone would not provide the required combination of properties.
Commercial grades are generally identified by their tungsten/copper ratio, such as:
- W50/Cu50
- W55/Cu45
- W60/Cu40
- W65/Cu35
- W70/Cu30
- W75/Cu25
- W80/Cu20
- W85/Cu15
- W90/Cu10
Manan Steel & Metals currently publishes Tungsten Copper Rods in this range of compositions.
For additional technical information about tungsten-copper materials, view the tungsten-copper alloy reference from Tungsten Heavy Powder.
Tungsten Copper WCu Grades
The grade of Tungsten Copper Rod is important because changing the tungsten-to-copper ratio changes the balance between conductivity, density, hardness and thermal properties.
| Grade | Tungsten | Copper |
|---|---|---|
| W50/Cu50 | 50% | 50% |
| W55/Cu45 | 55% | 45% |
| W60/Cu40 | 60% | 40% |
| W65/Cu35 | 65% | 35% |
| W70/Cu30 | 70% | 30% |
| W75/Cu25 | 75% | 25% |
| W80/Cu20 | 80% | 20% |
| W85/Cu15 | 85% | 15% |
| W90/Cu10 | 90% | 10% |
The exact composition tolerance depends on the applicable product specification.
As tungsten content increases, the material generally becomes denser and harder, while electrical conductivity decreases. Published WCu data from Tungsten Heavy Powder shows this trend across W50/Cu50 to W90/Cu10 grades.
This is why choosing the correct WCu grade is an application decision rather than simply a purchasing decision.
Tungsten Copper Chemical Composition
Tungsten Copper Rod does not behave like a conventional single-phase alloy.
It is a composite material, with tungsten and copper forming separate phases.
For example, Manan’s published specification gives:
W50/Cu50: approximately 50% copper with tungsten as the balance
W70/Cu30: approximately 30% copper with tungsten as the balance
W80/Cu20: approximately 20% copper with tungsten as the balance
W90/Cu10: approximately 10% copper with tungsten as the balance.
The exact grade should therefore be stated when ordering.
A purchase request saying only “Tungsten Copper Rod” is incomplete because W50/Cu50 and W90/Cu10 can have significantly different physical and electrical properties.
Tungsten Copper Rod Properties
The major advantage of WCu materials is the combination of tungsten’s high-temperature and wear characteristics with copper’s conductivity.
A published W80/Cu20 material datasheet gives representative values including approximately 15.6 g/cm³ density, 140 W/mK thermal conductivity and 30% IACS electrical conductivity. It also identifies applications including die-sinking EDM electrodes, resistance welding electrodes and electrical contacts.
Properties vary substantially with grade.
For example, published data from Tungsten Heavy Powder shows that W50/Cu50 has higher electrical conductivity than higher-tungsten grades, while W90/Cu10 provides higher hardness and density.
Important properties include:
| Property | Importance |
|---|---|
| Electrical Conductivity | Important for electrical contacts and electrodes |
| Thermal Conductivity | Important for thermal management |
| Hardness | Important for wear resistance |
| Arc Resistance | Important for switching and electrical applications |
| Density | Important for component design |
| Thermal Expansion | Important for thermal-management systems |
| Dimensional Stability | Important for precision applications |
Why Tungsten Copper Is Used in Industry
The key value of Tungsten Copper is that it combines characteristics that are difficult to obtain from conventional copper alone.
Copper provides excellent conductivity, but it is relatively soft and has a comparatively low melting point.
Tungsten provides extremely high-temperature capability and hardness, but its electrical and thermal conductivity are much lower than copper.
WCu combines these characteristics in a composite structure.
This makes it useful where components experience:
High electrical current
Heat generation
Arc erosion
Repeated electrical switching
Mechanical wear
High-temperature exposure
The exact WCu grade should be selected according to the dominant requirement.
Tungsten Copper Rod Applications
EDM Electrodes
One of the most important applications for Tungsten Copper Rod is Electrical Discharge Machining (EDM).
WCu can be used as an electrode material for selected EDM operations because of its combination of electrical conductivity, thermal conductivity and resistance to erosion.
A current WCu 80/20 datasheet specifically identifies the material for die-sinking EDM electrodes.
Resistance Welding Electrodes
Tungsten Copper can also be used for selected resistance-welding electrode applications.
Its combination of conductivity and resistance to heat and wear makes it useful where electrodes are exposed to repeated thermal cycles.
Electrical Contacts
WCu is used for selected electrical-contact applications, including high-voltage switching equipment.
The material can provide a useful combination of conductivity and resistance to arc erosion.
Circuit Breakers and Switching Equipment
Electrical switching components can experience extreme temperatures during arcing.
WCu materials are therefore relevant to selected high-voltage switching and circuit-breaker components.
Heat Sinks and Thermal Management
WCu is also used for selected thermal-management applications.
A tungsten-copper composite can offer useful thermal conductivity while providing a coefficient of thermal expansion different from pure copper.
Aerospace and Defence Components
Specialty tungsten-copper materials can also be considered for selected aerospace and defence applications where thermal and electrical performance are important.
The exact grade must be selected according to the component’s operating conditions.
Tungsten Copper Rod for EDM
For Tungsten Copper Rod for EDM, grade selection matters.
EDM electrodes must efficiently conduct electrical current while resisting erosion and maintaining dimensional accuracy during machining.
WCu compositions such as W70/Cu30 and W80/Cu20 are commonly encountered in EDM-related applications.
Published WCu 80/20 technical data specifically identifies the material as an electrode material for die-sinking EDM.
The required grade can depend on:
- EDM process
- Workpiece material
- Electrode geometry
- Required surface finish
- Machining current
- Pulse conditions
- Electrode wear requirements
For a production EDM requirement, buyers should provide the machine/process information wherever possible.
Tungsten Copper for Electrical Contacts
Electrical-contact applications require careful control of conductivity, arc resistance and wear.
WCu materials are particularly useful in selected applications where repeated electrical switching produces heat and arc erosion.
The appropriate tungsten/copper ratio depends on the electrical design.
Lower-tungsten grades generally provide higher electrical conductivity, while higher-tungsten grades generally provide greater hardness and density. Published WCu property tables demonstrate this relationship across multiple grades.
This makes the grade selection important for:
- High-voltage switches
- Circuit breakers
- Electrical contacts
- Resistance welding
- Power equipment
- Special electrical components
Tungsten Copper Rod Sizes and Finishes
Industrial requirements can vary considerably depending on the finished component.

What Affects Tungsten Copper Rod Price?
The Tungsten Copper Rod price depends strongly on the grade and dimensions.
Tungsten Content
A higher tungsten percentage means the composition contains more of the high-density tungsten phase and can affect raw-material cost.
Diameter
Large-diameter rods require more material and may require different manufacturing processes.
Length
Special cut lengths can affect material utilization.
Grade
W50/Cu50, W70/Cu30 and W90/Cu10 are not interchangeable products and can have different commercial prices.
Surface Finish
Polished and precision-ground rods can cost more than standard material.
Tolerance
Tighter tolerances require additional processing and inspection.
Quantity
Large production quantities can have different pricing from small quantities.

How to Select the Right WCu Grade
The best WCu grade depends on the application’s primary requirement.
For higher electrical conductivity, a higher copper fraction may be preferred.
For greater hardness, density and wear resistance, a higher tungsten fraction may be appropriate.
For example:
W50/Cu50
Suitable where higher copper content and conductivity are important.
W70/Cu30
A commonly considered balance for electrical and wear-related applications.
W80/Cu20
Higher tungsten content with useful conductivity and thermal properties.
W90/Cu10
High tungsten content for applications where density, hardness and arc resistance are particularly important.
These are general selection principles, not a substitute for an application-specific engineering specification.
