Aluminum is one of the most ordinarily involved materials in CNC machining activities. It gives you unique advantages that make CNC machining easier and save money when making products and parts. Aluminum is an excellent material for CNC machining because of its excellent machinability.
So Why Is Aluminum Ideal for CNC Machining?
Excellent Finishing
There are numerous surface finishing options for aluminum. A smooth, uniform surface finish can be achieved with the help of modern coolants and carbide tooling. A matte finish can also be achieved by bead blasting aluminum. To achieve the ideal, custom appearance, a variety of surface coatings, including painting and anodizing, are available. Aluminum that has been anodized will have a uniform appearance and be more resistant to corrosion.
Easy to Machine
Aluminum is still a strong metal despite having a density about one-third that of steel. Additionally, it is dimensionally stable. Because of these characteristics, it is suitable for CNC machine cutting and shaping operations while still maintaining its residual stress. The lower thickness of aluminum guarantees it won't twist or disfigure under cutting activities. This makes it possible to produce prototypes with tighter tolerances. CNC cutting machines can easily penetrate and cut a variety of aluminum grades.
Resistant to Low Temperatures
Aluminum's exceptional resistance to low temperatures is one of its strengths. Aluminum can be easily machined at low temperatures, whereas steel can be sensitive and delicate in low-temperature welding locations.
Quicker Turn-Around Times
Since aluminum is not difficult to cut, it requires less investment to create parts than different metals like steel or copper. If the situation calls for a quick turnaround and the application permits, aluminum is an excellent choice.
Less Expensive to Machine Than Other Metals
Aluminum is less expensive to machine than other metals because it can be machined faster and frequently does not require additional finishes.
Industrial applications of aluminum alloys
Most industries use aluminum CNC machining. It allows them to manufacture machined parts with ease.
Aerospace industry
Aluminum alloys are ideal for the aviation industry because of their excellent properties. The material is flexible, resistant to corrosion, and has a high strength-to-weight ratio.
Automotive industry
Aluminum can endure the weight and hence is appropriate for the car business. When manufacturing body parts and components, this property is ideal. Aluminum also contributes to emission reduction, which saves energy.
Marine industry
Non-heated alloys are ideal for the marine industry due to their ability to be welded and high resistance to corrosion. Parts that are precisely machined and smaller in size are needed by the marine industry. Material made of aluminum makes it possible.
