What is edm wire made of?

Wire EDM machines play an important role in modern manufacturing, especially in fields such as mold making or metal processing. The material of the electrode wire directly affects the efficiency and quality of wire cutting. This article will discuss the different materials of electrode wires for wire EDM machines and their characteristics.

Common electrode wire materials and their advantages and disadvantages.

Copper electrode wire.

• Advantages: Good electrical and thermal conductivity, suitable for processing high hardness materials, maintains good cutting performance at high temperatures.
• Disadvantages: Higher cost, limiting its range of applications.

Molybdenum electrode wire.

Molybdenum electrode wire is widely used in precision machining fields due to its high hardness and wear resistance. It is particularly suitable for processing hard materials requiring high precision. The use of molybdenum wire plays an important role in improving cutting precision and surface quality, but it is relatively expensive.

Copper-nickel alloy electrode wire.

• Advantages: Good wear resistance, suitable for processing thin plates and thicker hard materials, fast cutting speed, high quality.
• Disadvantages: Relatively new material, may have limitations in certain specific applications.

Iron electrode wire.

• Advantages: Sturdy and durable, less prone to vibration.
• Disadvantages: Poor electrical and thermal conductivity, suitable for processing low hardness materials.

Carbide electrode wire.

• Advantages: High hardness, good wear resistance, fast cutting speed, high quality.
• Disadvantages: Higher cost, limiting its widespread use.

Common cutting wire materials for fast, medium, and slow wire cutting.

Fast wire cutting.

• Material: Usually uses molybdenum wire, cost-effective.
• Application: Suitable for scenarios with relatively lower precision requirements and not high surface roughness.

Medium wire cutting.

• Material: Often uses brass wire, balancing cost and performance.
• Application: Suitable for general precision and surface quality requirements.

Slow wire cutting.

• Material: Disposable copper wire, more expensive, but offers better cutting precision and surface quality.
• Application: Suitable for tasks requiring high precision and high surface quality.
