Are you selecting the right materials for your CNC machined parts? You may be overlooking cost-effective alternatives that can satisfy part requirements.

Material affects everything from the design to the strength to the function of a part, so it’s important to get it right. Engineers can make educated decisions about material type, but a machine shop with deep knowledge of material properties can be a great resource for determining the ideal material. Form, function, and even availability are all important factors. 

When you request a quote from Focused on Machining, our Denver machine shop will provide expert material recommendations to reduce cost and lead time while ensuring the integrity of your part. But before we tell you how we can help, let’s bust some common myths about material selection! 

Busting Common Myths About Materials for CNC Machining

Myth #1: Aluminum isn’t very strong.

There’s a popular misconception that aluminum is a weak material, but there are many different grades and some are incredibly strong! Engineers tend to default to steel (or even titanium for aerospace applications) without realizing that aluminum is a cheaper option that can often get the job done.

Recently, one of our aerospace customers wanted a 4130 alloy steel part. After discussing the stresses and forces that would be applied to the part, we determined that an aerospace grade 7075 aluminum would satisfy their part requirements, which saved on cost and cut back lead time for the parts.

Myth #2: 4000 series alloys are only for aerospace applications.

The common assumption in the design world is that 4000 series alloys are only used for aerospace applications. In reality, many of our non-aerospace customers take advantage of the impressive properties of these metals. Across the board, 4000 series alloys have a better strength ratio than carbon steel. They don’t rust easily, and they’re readily available due to the large volume of aerospace work in the United States.

Myth #3: General terms are sufficient when discussing materials.

Did you know that there are well over a dozen different grades of aluminum? There are also many types of titanium, all with varying specifications and properties. Providing the general material type in your RFQ isn’t enough. We’ll want to drill down into the details to make sure we select the specific grade that’s perfect for your part.

How Focused on Machining Helps with Material Selection

There’s no need for guesswork when a skilled machine shop helps you select the right material for your part. 

Here’s what you can expect when you work with our team: 

• Unparalleled knowledge. We know a lot about metal! Our team understands material specifications and properties to make the best recommendation every time.

• Years of experience. We’ve made thousands of parts over the years and have experience working with many materials.

• Insight into material availability. Why put time and energy into selecting the perfect material only to find out that it’s nearly impossible to procure? Rely on us to help you choose a comparable material that’s easy to find or that can be purchased in the right quantity for your order.
