Tungsten needles can be used for electrical discharge machining (EDM). EDM is a manufacturing process that uses a series of electric sparks to erode material from a workpiece. Tungsten is an ideal material for EDM electrodes because it has a high melting point, high thermal conductivity, and excellent resistance to wear and deformation. Tungsten electrodes can be machined to precise shapes and sizes, making them suitable for a variety of EDM applications.
