Overview of Wire cutting wear resistant tungsten steel conductive block alloy material EDM conductive block
Tungsten is a metallic element with the element symbol W and atomic number 74. It is located in the VIB group of the sixth period of the periodic table of elements. In nature, tungsten mainly exists in the form of hexavalent cations. Its ionic radius is small, it has strong polarization ability, and it is easy to form complex anions.
When preparing pure tungsten or tungsten alloy, the main methods include powder metallurgy, smelting (including electron beam melting, vacuum melting, plasma beam melting) and chemical vapor deposition.
Feature of Wire cutting wear resistant tungsten steel conductive block alloy material EDM conductive block
The thermal expansion coefficient of tungsten is very low, only 4.5×10^-6 m/mK, so it has good thermal stability. These properties make tungsten widely used in manufacturing high-temperature components and reliable heat detectors.

Parameters of Wire cutting wear resistant tungsten steel conductive block alloy material EDM conductive block
The parameter for a wire cutting wear-resistant tungsten steel conductive block alloy material for EDM (Electrical Discharge Machining) is not a fixed set, as it can vary depending on the specific requirements of the application, manufacturer, and desired performance characteristics. However, here are some key parameters that you might find in such a material:
1. Composition: Tungsten carbide (WC) content is typically high, often around 90% tungsten carbide with a binder metal like cobalt (Co), iron (Fe), or chromium (Cr). The exact composition can range from WC8% to WC14% for higher wear resistance.
2. Hardness: Vickers hardness (HV) is usually in the range of 650-800 HV, indicating a very hard surface suitable for resisting wear during wire cutting.
3. Electrical Conductivity: Good electrical conductivity is essential for EDM, typically around 50-70% IACS (International Annealed Copper Standard).
4. Thermal Conductivity: A balance between thermal conductivity and heat dissipation is crucial; tungsten carbide has moderate thermal conductivity, which helps maintain tool stability during the EDM process.
5. Wear Resistance: High wear resistance is critical, as the material should withstand the repeated impacts of wire erosion during cutting. This is measured by its ability to maintain edge integrity and minimize tool wear.
6. Machinability: Although tungsten carbide is harder than most materials, it can be machined using EDM, but with slower speeds and higher current densities compared to softer alloys.
7. Dimensional Stability: The material should have good dimensional stability to ensure accurate part geometry after machining.
8. Thermal Expansion Coefficient: Low thermal expansion coefficient to minimize deformation during heating and cooling cycles.
9. Grain Structure: Fine-grained tungsten carbide provides better wear resistance and toughness.
These parameters are guidelines and may differ based on the manufacturer’s specifications and the specific needs of your application. Always consult the material data sheet or supplier for the most accurate information.
