www.fotmacarbide.com provide Customized Tungsten Copper Alloy Tubes / Pipes Surface Machined For Spark Erosion

Tungsten copper tubes are widely used in machinery, electronics, and aviation, aerospace, military and other fields.

Copper Tungsten Alloy uses the excellent metal characteristics of the high pure tungsten powder and the plasticity and high conductivity of the high pure copper powder to produce composite materials with static pressure molding, high temperature sintering and the the solution process of the copper infiltration technology.

These materials have some advantages: the arc ablation resistance, good thermal conductivity, and small thermal expansion, not soften in high temperature, softening, high strength, high density, high hardness etc.

Advantages of Copper Tungsten Tubes:

High arc resistance combined with good electrical conductivity
Low thermal expansion.
Strong hardness(86~93.5HRA)

High thermal conductivity

Applicatioins of Tungsten Copper Alloy:

Copper tungsten is very popular used in the EDM, since it has both tungsten and copper's character so it has very good wear resistance. Our copper tungsten alloy is made by vacuum infiltration technology. which has very good physical and mechanical propertie.

Electrodes for Resistance Welding

Arcing contacts and vaccum contacts in high and medium voltage breakers or vaccum interruptors

Electrodes in electric spark erosion cutting machines

Heat sinks as passive cooling elements of electronic devices

For the spark erosion of dies or cemented carbide making for high speed steel and switches and contacts in high and low voltage electrical devices.

Special shape products are produced as per customer's drawing.

Uses are as electrodes, heating elements and field emitters, and as filaments in light bulbs and cathode ray tubes. Tungsten is commonly used in heavy metal alloys such as high speed steel, from which cutting tools are manufactured. It is also used in the so-called 'superalloys' to form wear-resistant coatings

Both raw and finished Tungsten are available
