Tungsten-copper has unique material properties. A high level of temperature resistance is one of the most important advantages of tungsten, while the copper content increases the electrical and thermal conductivity.Tungsten copper (WCu) materials are used for arcing contacts in SF6 circuit breakers for high and medium voltage applications. At the heart of the switching chamber, WCu arcing contacts are exposed to extreme mechanical and thermal stresses. During arcing, the temperature can reach levels ≥ 20,000 K, for instance.

Specifications of Copper Tungsten :

  • Tungsten 80%-Copper 20%
  • Tungsten 70%-Copper 30%

Tungsten Copper alloy is an alloy composite of Tungsten and Copper which has the combination s of the excellent properties of Tungsten and Copper, such as heat resistance, aberration resistance, high density, excellent thermal and electrical conductivity. It is easy to be machine.


We Supply Tungsten Copper by Press, Sinter & Infiltration method with the tungsten content ranging from 50% to 90% by weight. The balance is copper.

1. Electrical Contact materials

Electrical contacts are subjected to extreme mechanical and thermal stresses during operation. For fractions of a second, temperatures rise to several thousand degrees as a result of the arcing. Only Tungsten Copper materials will stand these high temperature & aberration.


Tungsten Copper material has good resistance to arc erosion, mechanical wear, contact welding and good conductivity. They are usually selected for oil, gas, air or vacuum, devices. The contact surfaces will oxidize when switched in air. These press-sinter-infiltrate materials should only be considered for arcing surfaces in air when used as arcing tips, arc plates and arc runners. When switching with moderate contact arcing, the Tungsten Copper with a high copper content may give the lowest erosion. As arcing severity increases, the Tungsten Copper with the higher refractory content withstand arc erosion better. Tungsten Coppers are also used as arcing edges of selector switchblades in transformer tap changers.


2. Electrodes for Spark Erosion (EDM)

Tungsten Copper electrodes are best suitable material for electrical discharge machining (EDM) applications. It has excellent wear resistance, good metal removal rate and ability to retain good detail. It is used where speed and wear resistance are most important.


3. Resistance Welding

Tungsten Coppers are used for some spot welding application of low conductivity materials, and as die inserts for flash and butt resistance welding applications.


4. Heat Sinks

Modern computer processors like the 586 series and higher, generate a heat output per square centimeter similar to that of a household cooker surface. Tungsten-copper heat sinks and the processor fan remove the heat.

We manufacturer of drawing dies with tungsten carbide blanks inside as a cost effective solution for a wide variety of wire processing applications. Carbide dies are frequently and successfully used in wire drawing (round & shaped), bunching, stranding, guiding, and split die applications.

Typically tungsten carbide dies are used for manufacturing wire or rod, generally in highly abrasive and high carbon material areas where PCD dies are not cost effective. It is often used in short run applications where trials, testing or small lots are desired.

Tungsten Carbide dies can be made in a wide range of sizes, ranging from 0.127 - 76.2 mm (.005 - 3.000”) or larger upon request.

Like all products from Esteves Group you can expect these products to be manufactured with the highest quality and accuracy standards.

Tungsten carbide, abbreviated as WC or TC, also called cemented carbide, hardmetal or widia, is a metal matrix composite where tungsten carbide particles are the aggregate and metallic cobalt serves as the matrix. It is a non-oxidizing ceramic that can withstand high temperatures while maintaining a hardness comparable to corundum or sapphire.


Key benefits of our tungsten carbide dies

• Sizes are available up to 76 mm rod (3.0")
• Cost effective
• Even and round wear during usage
• Blanks are thermally stable up to 2870°C (5198 °F)



Tungsten carbide has been a base material for drawing dies for over 100 years and continues to be a viable option for many applications. These were, next to natural diamond dies, the first types of drawing dies manufactured by Esteves Group. Tungsten Carbide and Natural Diamond were the only materials for many decades. It wasn’t until the invention ofSSCD and PCD in recent years that the exclusive use of natural diamond and tungsten carbide was reduced.

Tungsten carbide dies are successfully used for applications that require high heat and shock resistance or when short runs are desired. The affordable cost of Tungsten Carbide makes this possible. Due to the relative ease of machinability and cost effectiveness; Tungsten Carbide is also the preferred material of choice for most shaped wire drawing dies.

Typical application areas:
• Steel wire
• Stainless steel wire
• Copper wire
• Aluminum wire
• Tungsten wire
• Various other ferrous and non-ferrous metal wire types

What's unusual about tungsten are the kinds of exotic alloys used to influence its performance in TIG welding. In order to distinguish one from another, a color code has been developed. Here are the most common choices, their colors, AWS and ISO numbers, and what they're used for:

Pure Tungsten - EWP -- Used primarily for AC welding of aluminum and magnesium at low currents. The tip of the tungsten is balled before using. (ISO = W)

Lanthanated 1.5% - EWla-1.5 --General purpose electrode used for steel and stainless steel at a wide range of current. Often used as a cheaper, safer substitute for thoriated tungsten. (ISO = WL15)

Ceriated 2% - EWTh-2 -- Can achieve high currents with good arc stability. Another substitute for thoriated tungsten. (ISO = WC20)

Thoriated 2% - EWTh-2 -- An expensive and radioactive metal. Use care in grinding (i.e. wear a dust mask), keep your skin covered and avoid contact with the metal when it's heated. (ISO = WT20)

Zirconiated 2% - EWZr-2 -- Another option for AC welding, zirconium is preferred in situations where resistence to contamination is paramount. The tip of the tungsten is balled before using. (ISO = WZ3)
