Product DescriptionHigh conductivity WCu alloy copper tungsten sheet price



What'scopper tungsten sheet?copper tungsten sheet(Copper Tungsten Alloy, CuW, or WCu) is a pseudo-alloy of copper and tungsten. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The alloy combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, high thermal and electrical conductivity, and easy to machine. Parts are made from the WCu alloy by pressing the tungsten particles into a desired shape, sintering the compacted part, then infiltrating with molten copper. Sheets, rods and bars of the alloy are available as well.Tungsten copper parts provided by us are all with these properties. 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.Chemical Composition of ourcopper tungsten sheet

is suitable for EDM machining of those materials.
Advantages: low wear, high contour sharpness,good machinability.
Tungsten copper electrode is a good use of high-purity tungsten metal powder and high purity characteristics of the plasticity of copper powder.
Tungsten copper electrodes can be divided into EDM electrode, high-voltage electrode discharge tube and electronic packaging materials
Tungsten copper alloy sheet/plate/bar
Specification:Thickness>1mm;Width<200mm;Length<300mm; Because of the high eletrical conductivity and low consumption, copper tungsten alloy bar are widely used to make Grid siderod, Lead, Support, Electrode for the Gas discharge lamp
Copper Tungsten Alloy Heat Sink
Copper tungsten alloy is widely used as heat sinks concerning with radiator for car, refrigeration and air conditioning systems, because of its low thermal expansion, heat-resistant, ablate-resistant, excellent thermal and electrical conductivity. WCu heat sinks galvanically plated with Ni or NiAu or electroless Ni plated Semi-finished products: up to 100x100mm with a thickness of 0.5 to 50mm.
Copper Tungsten Alloy Electrical Contacts
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. Our copper tungsten alloy materials are used owing to their unique physical properties.
