Products Description
Copper tungsten EDM Electrode is made of Tungsten copper alloy which combines the advantages of tungsten and copper. Tungsten has a high melting point (3410°C) and density, while copper possesses excellent electrical and thermal conductivity. Therefore, tungsten copper alloy exhibits characteristics such as high-temperature resistance, high strength, arc erosion resistance, high density, and excellent electrical and thermal conductivity.
In electrical discharge machining (EDM), electrodes transmit machining pulses and erode workpieces with minimal loss. By utilizing the high electrical conductivity, high melting point, and low thermal expansion of tungsten copper alloy, EDM can effectively save electrode materials, improve machining speed, enhance mold accuracy, and reduce tooling costs and maintenance expenses.
features
High Melting Point and High Density: Tungsten's high melting point and density give copper-tungsten electrodes excellent heat resistance and arc erosion resistance. This allows them to maintain stable performance even in high-temperature environments.
Excellent Thermoelectric Properties: The addition of copper significantly improves the material's electrical and thermal conductivity. This helps increase the material removal rate (MRR) and keeps the electrode wear rate (EWR) low.
Good Machinability: Compared to pure tungsten or pure copper, copper-tungsten composites are easier to machine. This reduces processing issues like the brittleness of tungsten and the stickiness of copper.
High Wear Resistance: Even under poor flushing conditions, copper-tungsten electrodes show outstanding wear resistance. This is due to tungsten's high melting point and density.
High-Quality Surface Finish: The uniform distribution of copper enhances the structural integrity of tungsten-copper electrodes. Through advanced powder metallurgy processes, molten copper evenly infiltrates the pre-sintered tungsten framework. As a result, a high-quality surface finish is achieved on the machined workpiece.
applications
Hard Alloy Machining: Copper-tungsten electrodes perform exceptionally well in machining hard alloys (such as tungsten carbide). They achieve high material removal efficiency while keeping electrode wear rates low.
Micro-Hole Drilling: In micro-hole drilling, copper-tungsten electrodes are preferred for their high precision and stability. They can produce small, complex holes with accurate dimensions.
Complex Shape Machining: For workpieces with intricate shapes, copper-tungsten electrodes enable high-precision machining, ensuring accurate dimensions and excellent surface quality.
Aerospace Applications: In the aerospace industry, copper-tungsten electrodes are used to machine high-temperature alloys and difficult-to-cut materials. They help manufacture critical components like nozzles and combustion chambers.
Automotive Manufacturing: In automotive production, copper-tungsten electrodes are used to machine engine and transmission parts, improving both efficiency and machining quality.
