Although copper and copper alloys are cheap and easy to use, because copper and copper alloy electrodes are not resistant to spark ablation, the electrode consumption is large and the processing accuracy is poor, sometimes requiring multiple processing. As the accuracy of molds and the use of many difficult-to-machine material components continue to increase, as well as the EDM process becoming increasingly mature, the use of tungsten copper materials as EDM electrodes is increasing day by day. At present, tungsten copper alloy can be used as electrode materials such as resistance welding electrodes, EDM electrodes, and plasma electrodes. During the EDM process, the role of the electrode material is to deliver processing pulses and remove the workpiece with minimal loss. Tungsten copper material has the characteristics of fast processing speed, high processing quality and low electrode material loss. Therefore, it has obvious advantages for finishing machining of high-speed tools and molds and difficult-to-machine materials. As an EDM electrode, tungsten copper material is required to have good electrical and thermal conductivity, as well as good resistance to spark corrosion, and the material structure must be very uniform and dense.
FAQs about silver tungsten and tungsten copper:
[Boyang Company] [Precautions for the use of tungsten, copper, silver and tungsten]
Please confirm that there are no defects, cracks or other abnormalities in the product when opening it.
Tungsten, copper, silver and tungsten have a larger specific gravity than steel products. Please pay full attention when using it to prevent the product from falling and injuring your hands or feet.
[Boyang Company] [Precautions on product shape]
The appearance of tungsten copper products after milling machine shaping, lathe shaping processing, and grinding machine processing is different, which is normal imagination.
[Boyang Company] [Tungsten Copper Silver Tungsten Processing Precautions]
.Cutting Processing
Tungsten copper silver tungsten alloy may be damaged due to impact or excessive processing when making thin walls with sharp corners. Deficiency occurs due to load. When drilling through holes of tungsten copper silver tungsten alloy products, please pay attention to the feed load force when the hole is about to be drilled to avoid processing defects.
Tungsten copper-silver tungsten alloy is non-magnetic. Please confirm that the product is firmly fixed before operation.
.Electrical discharge machining, wire cutting
The discharge and wire cutting speed of tungsten, copper, silver and tungsten products are relatively slow, which is a normal phenomenon.
[Tungsten Copper Silver Tungsten Electroplating Precautions]
Tungsten copper silver tungsten alloy is a metal powder crystal. Please avoid strong acid and strong alkaline cleaning before electroplating to avoid surface metal particles falling off and affecting the electroplating effect.
[Tungsten copper, silver and tungsten plating precautions]
According to the B/3 standard requirements, the hole detection of tungsten copper and silver tungsten alloy products is carried out with a magnifying glass. In any field of view, up to three holes larger than or equal to Aggregations that are equal to but less than, pores or aggregates that are greater than or equal to but less than.
Tungsten-copper (silver) alloy combines the advantages of metal tungsten and copper (silver). Among them, tungsten has a high melting point (the melting point of tungsten is 3℃ and the melting point of iron is 3℃) and high density (the density of tungsten is .3/3 , the density of iron is ./3) Copper (silver) has excellent electrical and thermal conductivity, and tungsten copper (silver) alloy (composition generally ranges from ~) has uniform microstructure, high temperature resistance, high strength, arc ablation resistance, high density, electrical conductivity, It has moderate thermal conductivity and is widely used in high-temperature resistant materials, electrical alloys for high-voltage switches, electrical machining electrodes, and microelectronic materials. As parts and components, it is widely used in aerospace, aviation, electronics, electricity, metallurgy, machinery, sports equipment, etc. industry.
A two-phase structure pseudo-alloy composed mainly of tungsten and copper (silver) elements. It is a metal matrix composite material. Since the physical properties of metal copper (silver) and tungsten are quite different, they cannot be produced by melting and casting. Nowadays, powder alloy technology is generally used to obtain them. The technological process of producing tungsten-copper alloy using powder metallurgy method is mixing of ingredients, pressing, forming, sintering, dissolution, infiltration and cold processing.

A very important application of tungsten copper material is as a switch for high-voltage electrical appliances. contacts. Electrical contact materials, also known as contacts or contacts, are key components of high and low voltage electrical appliances. They are responsible for connecting and breaking current, and directly affect the reliability and service life of switches and electrical appliances. During the arcing process of the tungsten-copper alloy contact, the copper with a low melting point on the surface melts first and is adsorbed in the capillary holes of the tungsten skeleton due to capillary action. It evaporates under the high temperature of the arc and takes away a large amount of heat, cooling the tungsten skeleton, thus making the contact The contacts have good breaking performance. Due to the high melting point of the tungsten skeleton, the ablation in the arc is minimal, and welding will not occur even if the local temperature is too high, thus ensuring the stability, reliability and long life of the switch performance. Moreover, the higher the tungsten content, the better the anti-burning performance, but the conductivity is low, and specific choices must be made for specific uses.
