Aluminum Alloys for CNC Machining

The most common aluminum alloys AT-Machining used for cnc milling or cnc turning are 6061 and 7075. 

Both alloys have unique benefits that make them well-suited for different applications. It is important to choose the right alloy for the specific needs of a project.

  • Aluminum 6061 is known for its low cost, versatility, and excellent corrosion resistance. It is also easy to weld and machine, making it a good choice for many projects. Anodizing provides excellent protection against corrosion and gives 6061 aluminum a superior appearance.

 

  • Aluminum 7075 is prized for its high strength and hardness, making it an ideal choice for products that must withstand high loads or extensive wear and tear. 7075 aluminum is also low in weight and resistant to corrosion. Anodizing can further improve the corrosion resistance of 7075 aluminum and give it an attractive appearance.

Rapid Prototyping

CNC Aluminum Prototype Machining

The aluminum CNC prototyping process is a great way to find and solve problems before you mass-produce your product. It allows for more efficient design verification, which means that any issues can be found early on in production – stopping them at the source.

We know that every company has a different budget and schedule. So, we offer our customers the best machining process for their money- it’s all about finding what works! We use state of the art equipment to make sure your prototype aluminum parts meet high standards with minimal downtime or wasted material.

CNC Machined Aluminum Applications

Aluminum parts can be found everywhere, in a range of industries, especially automotive, aerospace, industrial equipment and machinery, and consumer and computer electronics.

Surface Finishes For CNC Machined Aluminum Parts

Many types of surface finishes can be applied to CNC machined aluminum parts. The most common finishes AT-Machining provides are anodizing, powder coating, bead blast and plating. Each of these finishes has unique benefits. Choose the one best suits your needs!

Name Description
aluminum as machined As machined The machined aluminum parts are left with visible tool marks and potentially sharp edges and burrs, which can be removed upon request.
aluminum alloy beadblasted finish Bead Blasted Give the machined parts a smooth and uniform matte surface finish, thereby removing tool marks.
aluminum polished Polishing Creating a smooth and shiny surface by manually polishing in multiple directions or by applying a chemical polish treatment.
aluminum anodizing color Anodizing Type II (Anodizing color or clear) or Type III (Anodizing hard coat) Anodizing does not cover tool marks unless bead blasted beforehand.
aluminum chromate conversion coating Chromate Conversion Coating Increase the part's corrosion resistance while retaining its conductivity. RoHS compliant.
aluminum decoretive plating Decorative Chrome Plating Enhance aesthetics and durability of the cnc aluminum components.
aluminum powder coat Powder Coat Applying powdered paint to the components and then baking it in an oven, which results in a stronger, more wear- and corrosion-resistant layer that is more durable than traditional painting methods.

How much does it cost to CNC aluminum?

The price of aluminum machining can vary depending on the material, size and complexity.

The cost to machine aluminum can be broken down into two categories: material and labor.

For small or complex parts, the processing fee is usually the biggest component of the total cost. On the”other hand, the material cost is usually the most significant factor to consider for large and simple parts. It is important to keep both in mind when budgeting for your project so you have a clear understanding of what the total cost will be.

The labor cost of CNC machining aluminum parts is determined by two factors: the number of hours worked and the rate charged per hour by the machinists directly working on the project. Both must be taken into consideration when calculating the total cost of production. As common, highly skilled labor often comes at a higher price.

What materials can be used to replace aluminum in CNC machining

         Aluminium is an excellent metal, but it’s not perfect. Other similar materials may work better for your project!
         Here’s a list of some potential machining alternatives to aluminum, with an emphasis on their differences and similarities.

Steel & Stainless Steel

Stainless Steel alloys offer a high degree of strength, ductility and wear resistance. They can be easily welded or machined to improve their surface finish if needed – making them perfect for many applications!

Applications: The benefits of using CNC machining for your part are huge, with excellent mechanical properties and accuracy in both metal or plastic. In addition to this 3-axis & 5 axis milling is available which can produce parts

Advantages over aluminum: Strength & Temperature resistance

Disadvantage against aluminum: Machinability & Weight

Titanium

Titanium is a metal with an excellent strength-to-weight ratio, low thermal expansion, and high corrosion resistance that is sterilizable and biocompatible.

Applications: Titanium is a strong, lightweight metal that has many of the same benefits as aluminum. It’s corrosion-resistant and comparable in weight to its counterpart but trades off some other properties for those features – namely strength versus ductility (or flexibility).

Advantages over aluminum: Strength-to-weight ratio

Disadvantage against aluminum: Cost

Copper

Copper offers excellent thermal and electrical conductivity, it’s often used for busbars, wire connectors, and other electrical applications. Copper has a glossy reddish-orange appearance.

Applications: Copper has many material properties that make it similar to aluminum. However, the superior electrical conductivity of copper can be used in various applications where purer metal is preferred or needed for better performance. Many alloys offer machinability on par with popular grades from this family as well

Brass

Brass is a metal alloy with good machinability and excellent electrical conductivity. Ideal for applications that require low friction.

Applications: Low friction, excellent electrical conductivity, golden appearance. Brass is a metal alloy with good machinability and excellent electrical conductivity. Ideal for applications that require low friction.

Advantages over aluminum: Some aesthetic applications
