custom made circuit breaker 80%w tungsten copper alloy arcing contacts

Product Descriptioncustom made circuit breaker 80%w tungsten copper alloy arcing contacts



copper tungsten arcing contact Owing to the good performance of electrical conductivity, tungsten copper contact can be used as electrical contact material, The high electrical and thermal conductivity of copper are combined with the arc-resistant and non-welding properties of tungsten or their carbides to form an extensive series of compositions. Each is designed to give the best performance for your particular application.
We are able to influence thecopper tungsten arcing contactarc erosion properties by choosing the right mixture of tungsten and copper. With tungsten content reaching at 80 %, we achieve the lowest arc erosion rates. Depending on the voltage and current intensity as well as on economic considerations, we can vary the tungsten content between 50 and 93 % to meet the exact needs of clients' application.
For switch contacts, we also have copper tungsten carbide contacts or CuWC contacts for your inquiry. With high density, high strength and hardness, arc wear resistance, copper tungsten carbide contacts is wildly used as the electrical contact and electrode too.

What's Tungsten Copper Alloy?
Tungsten copper alloy (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.

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 alloy 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.
