Copper tungsten bars are a combination of two high-performance metals that deliver superior wear-resistance, arc and wear resistance, high physical properties at elevated temperatures, and good electrical and thermal conductivity. They are widely used in various industrial applications, most notably spark erosion and electro-chemical machining.
Spark erosion is a non-conventional machining process that utilizes a series of high-voltage electrical discharges to remove material from a conductive workpiece. This technique is widely used in the manufacturing of precision parts that require high accuracy, complex geometries, and excellent surface finish. In spark erosion, copper tungsten bars are used as electrodes because of their outstanding wear resistance, good electrical conductivity, and low electrode wear.
Electro-chemical machining, on the other hand, is a non-traditional machining process that uses an electrolyte and an electrode to dissolve metal from a workpiece. This technique is particularly useful in the machining of complex geometries, hard-to-machine materials, and delicate parts that are easily damaged by conventional machining methods. Copper tungsten bars are commonly used as electrodes in electro-chemical machining because they offer excellent wear resistance, high thermal conductivity, and resistance to chemical attack.
In both techniques, copper tungsten bars play a critical role in delivering high-precision, high-quality parts. They offer several advantages over traditional electrode materials such as graphite, brass, and copper. For instance, copper tungsten bars have a higher melting point than pure copper, making them ideal for high-temperature applications. They are also more wear-resistant than brass and have better electrical conductivity than graphite.
