How to Make Tungsten Copper

The method of tungsten copper machining is mainly divided into two categories: infiltration and direct sintering method. In recent years, due to the rapid development of nanotechnology, directly obtained by sintering a great development.The melting point of tungsten, copper vary greatly higher than the boiling point of the copper melting point of tungsten and tungsten copper immiscible, the general method of smelting is difficult to produce tungsten copper alloy, the only powder metallurgy to make tungsten copper composites manufacturing to become a reality.

Tungsten copper machining include the following methods:

Infiltration Method

High Temperature Sintered Tungsten Copper Alloy

Mixed Powder Sintered Copper Infiltration Method

Direct Sintering Method

Our general method is infiltration, the infiltrated divided into high temperature sintered tungsten skeleton copper infiltration and low-temperature sintering mixed powder copper infiltration two.

Tungsten Copper Material MSDS

Material Safety Data Sheet (MSDS) is a table about data regarding the properties of a particular substance, which may concern instructions for the safe use and potential hazards associated with a particular material or product. Therefore, MSDS is important and necessary for chemicals users.

Of course, the tungsten copper we provided also have MSDS, and more about tungsten copper’s MSDS please feel free to visit: http://www.tungsten-copper.com/MSDS-of-tungsten-copper.pdf

At the same time, following is the picture about our tungsten copper products, which are suitable for the MSDS:

The sheet aims to offer workers and emergency personnel with procedures for handling or working in a safe way, and includes information such as physical data (melting point, boiling point, flash point, hardness, ultimate tensile strength, density, etc.), toxicity, health effects, first aid, reactivity, storage, disposal, protective equipment, and spill handling procedures. The exact format for MSDS can vary from countries to countries by respective national requirement.

Tungsten Copper EDM Electrode

Tungsten copper EDM electrode is a powder metal product designed to combine the best EDM properties of tungsten and copper. Tungsten copper combines the high electrical conductivity of copper with the high melting point of tungsten. The combination of these two metals creates an electrode material with very good wear properties.

The manufacturing of Copper Tungsten Electrodes is telling about a combination of two metals: copper and tungsten. So this is a product is caring the properties of both the metals. Copper tungsten rod is highly heat resistant and conductive. 10 – 50% copper is incorporated according to the demand of usability.

Features of Copper Tungsten EDM Electrodes:

Thermal and electrical conductivity up to a high limit

Available in both finished and semi finished shape

Our product range also comprises of tungsten copper bar, tungsten copper blocks and other tungsten copper products. And if you have any other inquiries about our products, please do not hesitate to contact us with: sales@chinatungsten.com

Tungsten Copper Electrical Contacts

Tungsten copper electrical contacts have 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.

The high Electrical & thermal conductivity of copper are combined with the arc-resistant & no-welding properties of Tungsten or their carbides to form an extensive series of compositions each designed to give the best performance for your particular application. 

Tungsten copper 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 Iron Composite

Tungsten copper iron composite electrode also called tungsten copper petiole electrode. One end of the material is tungsten copper alloy, the other end is a relatively high tensile strength steel.

Tungsten copper with iron composite is developed in response to customer requirements, a new process technology, using a complex method of manufacturing the pressure. Combined with the end face of tungsten, copper and iron close no holes, the overall low contact resistance, and high tensile strength.

Tungsten copper composite electrode material is copper, steel two materials by explosive welding composite, combined with high strength, good electrical conductivity, direct sawing, milling and grinding. In the discharge machining precision parts IC, which is a good overall performance copper electrode can not be replaced, to improve the processing accuracy of parts and reduce overall costs is the most important feature of this material. This material has been widely used in foreign countries, our company can be customized with different ways of complex products according to customer requirements.                 

Tungsten Copper Rod Description

Tungsten copper rod is a kind of round rod. The grade of tungsten copper rod include WD10070、WD10075 and WD10080. the choice of tungsten copper content are depend of the application of tungsten copper rod, but if you do not know the detail application of the material, you can choice the content according to GB/T8320-2003.

Tungsten copper rod is a kind of composite material, which is manufactured by high-purity tungsten powder and high conductivity copper powder with the production process of isostatic pressing, sintering temperature and copper infiltrated.

Tungsten copper rod properties include breaking arc performance, good thermal conductivity, low thermal expansion, in high temperature will not soften, high strength, high density and high hardnes.

Tungsten copper rods are mainly used in resistance welding electrodes, EDM electrodes, high-voltage discharge electrodes and electronic packaging materials.

Tungsten Copper Spring Contacts

Tungsten copper spring contacts is suitable for using the circuit up to the rated voltage 660V AC 50HZ or 60HZ, rated current up to 95A, for making, breaking, frequently starting and controlling the AC motor. Combined with the auxiliary contact block, timer delay and machine interlocking device etc. it becomes the delay contactor, mechanical interlocking contactor, star-delta starter. It is combined into the electromagnetic starter.

On account of their excellent properties, tungsten copper spring contacts materials have found a wide field of applications. Tungsten copper spring contactss are used successfully with high tungsten content as burn-off contacts for large low-voltage circuit breakers and with lower contents as contacts carrying a steady line current for molded case circuit breakers and in various protective circuit breakers. These tungsten copper spring contactss are also used in high current contactors where resistance to contact welding and arc erosion are required. 

The copper and tungsten composite group combines the high thermal and electrical conductivity of copper with the high erosion resistance of the high melting tungsten. These materials are also characterized by their high strength and their resistance to welding or sticking. They are principally made by infiltration and the nominal copper content varies from 10-50%. By increasing the amount of tungsten, the hardness and welding is reduced. This composite group of alloys is specially preferred for use in air.
