Tungsten Copper Linner

Tungsten copper linner combination of high density and ductility of tungsten copper, compared to copper liners have higher power and armor shaped effect. The disadvantage is that tungsten and copper can not dissolve each other, and because of the density difference between the two large, easy to form when gravity segregation caused by compression molding liners inhomogeneous density distribution.

Tungsten copper alloy as an ideal material for liners, but there is more in the preparation process issue, tungsten copper alloy bonding strength is poor, molding material difficulties; its wear deep fried sensitive to high variability, it should only lower Fried use under high conditions.

You can improve the disadvantage of tungsten copper linner by the following:

1, a conventional tungsten copper alloy density difference obtained by the method, the uneven density distribution, a more effective method for mixing powder or the preparation of molding can be used, including isostatic pressing and the like.
2, changing the sintering temperature and obtain better bonding strength.
3, on the layered liners do question whether it will result in poor stability problems.
4, if the density and bond strength can be improved, and then use the company's strengths, the material is rolled into sheets, tungsten copper alloy Liner material prepared by spinning, stamping or forging methods.

90W10Cu Tungsten Copper Sheet

90W10Cu tungsten copper sheet mainly used to suppress the high-speed technology to prepare, and then in 1400 ℃ high temperature hydrogen furnace infiltrated get 90W-10Cu composite. Research repression affect the quality of the pyrometer compacts green density and microstructure of. The results of surface, with the suppression of the temperature rise, the compact density, high-speed suppression obtained at 950 ℃ relative density greater than 80.65% of W skeleton dense tungsten particles connection, distribution, pore connectivity is good. Compacts increases quality, due to the applied energy density is reduced, leading to the green density decreases. By twice the height of repression, the green density further increase; the relative density of 99.5% 90W10Cu materials, thermal conductivity 175W / (mK), tungsten copper alloy 90W10Cu indicators have reached the requirements of the appropriate heat sink material.

90W10Cu Tungsten Copper Sheet Properties Conclusion

1, At 950 ℃ high speed pressing attainable relative density greater than 80.65% of W skeleton, by infiltration get 90W10Cu composites.

2, At room temperature, 600 ℃, 950 ℃ for high-speed tungsten preform pressing, pressing as the temperature rises, the green density increases.

3, High velocity compaction,  powder mass increases, due to the ability of additional density decreases, resulting green density decreases. With the increase in the number of high-speed pressing, green density is improved.

4, Using high-speed pressing technology combined with infiltration of 90W-10Cu preparation material and the thermal expansion coefficient and other indicators have reached the requirements of the appropriate heat sink material.

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.

The following is the picture about our tungsten copper maching method:

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.
