Aluminum Machining Services
Aluminum is particularly easy to shape and recycle, making it one of the most popular material choices for CNC machining. This material is malleable and durable, offering longevity while still being lightweight. At McCormick Industries, we utilize Swiss-style turning centers to achieve incredibly precise tolerances. Our aluminum machining services are highly efficient and cost-effective thanks to the use of live tooling and multi-axis machining.
The Benefits of Machining Aluminum Parts
Aluminum has a variety of properties that make it ideally suited for CNC machining. The following are some of the biggest advantages of working with this material.
High Strength-to-Weight Ratio
Two of aluminum’s most important properties are its light weight and high strength. This combination of factors make aluminum ideal for high-performance machined parts such as those in the automotive, marine, and aerospace industries.
This material is very easy to shape due to the fact that it chips fairly easily. As such, manufacturers utilizing aluminum for CNC machining are able to create high precision parts rapidly and accurately. When machining aluminum, speeds and feeds are typically 3 – 4 times faster than when machining steel.
This material comes in many grades, each offering different degrees of corrosion resistance. This gives manufacturers flexibility in choosing the appropriate option, with many grades offering significant corrosion resistance properties.
With an electrical conductivity of approximately 37.7 million siemens per meter at room temperature, pure aluminum is more conductive than most other commonly machined materials. As such, aluminum is often the material of choice for electrical components.
CNC machining naturally produces a fair amount of waste as it chips material away from the workpiece. Aluminum is fortunately very easy to recycle, thus saving money and reducing the environmental impact of production.
Surface Finishing and Anodization Potential
Many products require an additional finishing process, either for aesthetic or functional purposes. Aluminum offers the option of numerous surface treatments, including painting and anodization.
Aluminum is more affordable than some other machining materials, such as titanium and brass. Its recyclability contributes further to cost savings, and its light weight means that transportation is less costly.
Aluminum Machining Applications
The many advantages of working with aluminum make it an ideal choice for a range of industries including:
- Electrical and Electronics
Aluminum’s durability, electrical conductivity, and lightweight nature mean that it is well-suited for components that require a high degree of precision and strength. Although this material can be found in a wide array of components, some of the most common applications for aluminum include:
- Dowel pins
- Custom ferrules
- Medical devices
- Spline shafts
- Auto parts
- Aerospace components
- Construction tools
- Handles and knobs
Types of Aluminum for Machining
The many grades of aluminum provide manufacturers with some flexibility in determining the qualities that are most important for each project. Every aluminum grade offers varying degrees of corrosion resistance, strength, machinability, and weldability. When choosing the appropriate grade, it is helpful to consider the product’s intended use and choose the properties that are most important for success. While 6061 is the most common type of aluminum alloy used in machining, a few of the most popular aluminum grades include:
- 2011 Aluminum
- 2024 Aluminum
- 3003 Aluminum
- 5052 Aluminum
- 6061 Aluminum
- 6082 Aluminum
- 6063 Aluminum
- 7075 Aluminum
