A look at what influences the cost of CNC machining metals and what the most cost-effective options are.

When it comes to the cost of CNC machining, there are a number of factors that need to be taken into consideration. For instance, in a previous blog post, we looked at how part design can influence the cost of CNC machining. Today, we’ll look at how material choice, and specifically metals, can have an impact on the price of machining.

Metals suitable for CNC machining are each distinguished by different mechanical properties—like strength, ductility, corrosion-resistance, and others. These properties result in a range of machinability factors, meaning that some materials (with good machinability) are easier to mill and machine than others.

Generally, the easier the material is to be machined, the cheaper it is to work with. This is because highly machinable metals can be processed more quickly, which drives down CNC costs. However, the cost of raw materials must also be taken into account, as it can affect the overall cost of machining.

At RapidDirect, we offer a comprehensive metal material selection for CNC machining, including many of the most popular CNC materials and more specialized options. Our range of available materials, which can be consulted in full here, covers various applications. Below, we’ll take a look at the most cost-effective metals to the CNC machine.
