Product Description

Higher Density CuW Alloy Copper Tungsten Electrodes Tungsten Copper Tube



Copper Tungsten Electrodes (CuW, WCu) is recognized as a highly conductive and wear-resistant composite material. It is widely used in tungsten copper electrodes in EDM and resistance welding applications, electrical contacts in high voltage applications, and thermal Heat sinks and other electronic packaging materials in applications.

The most common ratios of tungsten to copper are WCu 70/30, WCu 75/25 and WCu 80/20. Other common ingredients include 50/50, 60/40 and 90/10 of tungsten/copper.

The electrical and thermal properties of the alloy vary with different proportions. Copper increases the thermal

conductivity, which plays a huge part when being used in circuit breakers.
Electrical resistivity with an increase in the percentage of tungsten present in the alloy, ranging from 3.16 at 55%

tungsten to 6.1 when the alloy contains 90% tungsten.
An increase in tungsten leads to an increase in ultimate tensile strength up until the alloy reaches 80% tungsten and

20% copper with an ultimate tensile strength of 663 MPa.
After this mixture of copper and tungsten, the ultimate tensile strength then begins to decrease fairly rapidly.

Manufacturing Process
Part of the mixed powder sintering process copper infiltration method generally has the following two: tungsten

copper plates image Cu powder and 0.5% to 2.5% additives (typically nickel powder) - press molding - sintering -

copper infiltration. The process is simple; this method is suitable for manufacturing Cu> 20% tungsten-copper


Various methods to the production of tungsten copper materials, copper distribution along the tungsten grain

boundaries, the tungsten skeleton strength is not as good as the high-temperature sintering method, as this

method of asking too much of raw materials, ingredients, or the product will contain more impurities and gases.

BW powder - +2.5% Cu powder + static acid - was added to the appropriate melt composite adhesive agent

(containing 35% polypropylene, 60% paraffin wax, 5% satiric acid) - the cooling granulation injection form - binder

removal - heptanes - 3C% / min heating to 500C, 10C/min heating to 900C - transferred to the high-temperature

sintering furnace cooling - heating 10C/min to 1030C - to 10C/min heated to 1200-16200C Melting leaching - cooled

to room temperature. The manufacturing process of tungsten copper plates are according to these steps, which

owns properties of tungsten and copper.

Copper Tungsten Electrodes is used in a product or part requires high heat resistance, low thermal expansion and high

electrical or thermal conductivity. Tungsten copper is used to fabricate engines and electrical devices. It is also used

in the fields of aviation and spaceflight. Electrodes, refractory parts, heat sinks, rocket parts and electrical contacts

are all made by copper tungsten alloy. The alloy is also made into sheet metal, tubing and plate metal. Copper

tungsten alloy is used to make contacts for both high and medium voltage electrical devices, and for high speed

steel devices and switches.
