Electronic copper parts

The characteristics of turning copper parts

Copper alloy machining (turning, milling) has excellent performance and low resistivity. Good ductility, high thermal and electrical conductivity, so it is the most commonly used material in cables, connectors, and electrical and electronic components. It can also be used as a building material and can be composed of many kinds of alloys. The most important of these are: beryllium copper, phosphor bronze, bronze and brass. In addition, copper is also a durable metal that can be recycled many times without compromising its mechanical turning and milling performance.

CNC machining of copper electrode

During EDM machining, the copper electrode and the workpiece are respectively connected to the two poles of the pulse power supply. The pulse voltage applied to the copper electrode and the workpiece generates spark discharge. The instantaneous temperature of the discharge can be as high as 10,000 degrees Celsius, and the high temperature makes the surface of the workpiece partially vaporized or melted.
