Copper Tungsten PCD Disk Electrode
Copper Tungsten PCD Disk Electrode Description
Material selection and processing
The ratio of tungsten and copper is determined according to the specific requirements, and then it is processed by forging, turning, grinding, drilling, surface treatment, etc. We have the most advanced production equipment and a professional technical team, and all products will undergo comprehensive quality inspection before shipment.
Characteristics
- Excellent electrical and thermal conductivity, low electrode loss, and high welding efficiency.
- High hardness, good wear resistance, strong anti-deformation ability, and long service life.
- High melting point, good dimensional stability under high temperature environment.
- Good anti-adhesion, fewer welding defects, and improved welding quality.
Application
- Electrospark machining (EDM): In the production process of PCD tools, EDM is often used to accurately shape and process PCD materials. As an EDM electrode, the tungsten-copper alloy seam welding electrode wheel can quickly conduct current and heat, achieve efficient electric spark discharge, and accurately remove PCD materials to process tools of various shapes and sizes. It can also be used for the EDM repair process of PCD tools to restore them to a good cutting state and extend the service life of the tool.
- Metal processing: Used for seam welding of various metal pipes, such as stainless steel pipes, copper pipes, etc. Its good electrical conductivity and thermal conductivity can make the welding process more stable and improve the welding quality and pressure resistance of the pipe.
- Automobile manufacturing: Used for sealing and welding of parts such as body structures, engines or transmissions to meet the high precision and reliability requirements of automotive parts and improve service life.
- Electronics and electrical appliances: Used for welding precision electronic devices, housings of electrical equipment, etc., can quickly conduct welding current and heat to ensure the performance and quality of electronic components.
- Aerospace: Used for welding aircraft structural parts and engine components. It can maintain a stable shape and dimensional accuracy during the welding process and meet the high-precision welding requirements of this industry.
