Brass has good ductility, electrical conductivity and thermal conductivity. Various machined copper parts are widely used in automobile, valves, faucets ,gas gun fitting ,aerospace, medical and other industries. And brass is one of the materials that is easy to machine.
The type of metal chosen often determines the time spent machining it. Selecting a metal with low machinability would extend the CNC machining time considerably, as opposed to selecting a metal like aluminum with its high precision machinability. Furthermore, the longer the time spent machining, the more expensive the manufacturing process becomes.
Another factor that determines machining time is the complexity of the parts. A CNC machine would spend more time machining a complex part than a simple part, which also increases CNC machining costs.
The proposed use of CNC machined parts is another factor that would determine the choice of metal. For instance, when making parts that would experience heavy stress and loading, a metal with high strength, like steel alloy, is better than copper.
On the other hand, where the final product should have strength similar to steel but without its weight, like in the manufacturing of aircraft, then titanium might be ideal.
Additionally, the environment in which the part would operate is another factor that should determine the metal used for making the part.
The type of metal selected also determines the finishing and post-processing of the machined parts. For instance, soft metals or hard metals with low machinability often have tooling marks and burs, which finishing and post-processing help remove.
Although finishing and post-processing improve the appearance of a metal part, it also raises the cost of machining significantly. However, knowing the finishing and post-processing required makes it easier to choose the right metal for part metal fabrication. In most cases, it will be a metal with high manufacturability if a high-quality surface finish is important.
