How to choose the right materials for your CNC machine parts

Did you pick the right material for your CNC machine parts? You may have overlooked a low-cost alternative that can meet the demand for parts.


Materials almost influence everything from design to strength to function, so it’s important to use them correctly. Engineers can make informed decisions about material types, but machine shops with a deep understanding of material properties can be an important resource for determining the ideal material. Form, function, and even usability are all important factors.


When you request a quote that focuses on machining, our Forlong precision machining Ltd will provide expert material advice to reduce costs and lead time while ensuring your partial integrity. But before we tell you what we can do, let’s break down some common misconceptions about material selection!


Breaking a common myth about CNC materials

  • Myth# 1: Aluminum is not very strong, there is a popular misconception that aluminum is a weak material, but there are many different grades, some are very strong! Engineers often use steel (or even titanium for aerospace applications) by default, unaware that aluminium is often a cheap alternative to getting the job done. Recently, one of our aerospace clients wanted a 4130 alloy steel part. After discussing the stresses and stresses on the part, we determined that aerospace grade 7075 Aluminium Alloy would meet their part requirements, thus saving costs and shortening part delivery times. In fact, many of our non-aerospace customers take advantage of the impressive properties of these metals.

  • Myth # 2 In general, the strength ratio of the 4000 series is higher than that of carbon steel. They do not rust easily, and because of the extensive aerospace work in the United States, they are readily available.

  • Myth # 3: Is General Terminology Sufficient when discussing material? There are many types of titanium, all with different specifications and properties. It is not enough to provide a general type of material on your inquiry sheet.

  • Focusing on machining helps in material selection when a skilled machine shop helps you choose the right material for your parts, there is no need to guess.
