Selection of electrode wires
Electrode wires are essential for wire EDM. They must have good conductivity, good erosion resistance, high tensile strength and uniform material. Common materials are molybdenum wire, tungsten wire, tungsten-molybdenum alloy wire, brass wire and copper-tungsten wire.

Tungsten Wire : High tensile strength, diameter between 0.03 and 0.1 mm, generally used for fine cutting but expensive.
Brass wire : Suitable for slow speed processing, has good surface finish and straightness, but has low tensile strength and high wear, with diameters of 0.1-0.3mm.
Molybdenum wire : High tensile strength, used for forex dataset high speed wire cutting, with diameters of 0.08 to 0.2 mm.
The choice of electrode wire diameter should depend on the width of the cut, the thickness of the part and the size of the corner. For small molds with sharp corners and narrow cuts, it is better to use thinner wires. For thick parts or high current cuts, thicker wires should be used.

Wire cutting, or EDM wire cutting, can be compared to laser cutting, water cutting and plasma cutting:

Laser cutting : Uses a focused laser beam to melt, vaporize, or burn material, using a high-power laser. CO2 pulse lasers are commonly used for precise cuts.

Water cutting : Uses high-pressure water jets, which can cut any material with minimal thermal impact. There are two types: ordinary water cutting and abrasive water cutting.

Plasma cutting : It uses high-temperature plasma arcs to melt and eject material, allowing various metals to be cut with noticeable thermal effects.

1. Comparison of application areas
Laser Cutting : Widely applicable to metals and non-metals. Suitable for cutting fabrics, leather and metals, with CO2 lasers for non-metals and fiber lasers for metals.

Water cutting : Suitable for all materials without thermal deformation, with good cutting quality and flexible dimensions, suitable for all materials to be drilled and cut.

Plasma cutting : Suitable for metals such as stainless steel, aluminum, copper, cast iron and carbon steel, with significant thermal effects and lower precision.
