Benefits of Aluminum for CNC Machining
Low Density: Aluminum’s low density makes it ideal for applications where weight matters. From aerospace components to consumer electronics, aluminum parts contribute to overall weight reduction.
Mechanical Properties: Aluminum alloys, such as 6061-T651, 7075-T651, and 2024-T351, strike a balance between strength, machinability, and cost. These alloys offer excellent mechanical properties.
Thermal and Electrical Conductivity: Aluminum conducts heat and electricity efficiently, making it suitable for heat sinks, electrical enclosures, and connectors.
Corrosion Resistance: Aluminum naturally forms a protective oxide layer, preventing corrosion. Anodizing further enhances this property.
Common Aluminum Alloys for CNC Machining
Aluminum 7075 T651 and T7: Known for high strength, hardness, and heat tolerance, this alloy is used in aerospace, automotive, and industrial applications.
Aluminum 2024 T3: With a high strength-to-weight ratio and excellent corrosion resistance, this alloy is popular for structural components.
Aluminum 6061 T651: Although not as strong as other alloys, it offers superior corrosion resistance and an attractive appearance after anodizing.
Finishing Options
Anodizing is a common finishing technique for aluminum parts. Here are the three types available:

Type I - Chromic Acid: Provides a thin but durable coating. It’s commonly used for welded parts and as a primer before painting.
Type II - Sulfuric Acid: Harder than Type I, it offers exceptional durability. Examples include carabiner hooks and flashlight handles.
Type III - Hard Anodize or Hardcoat: The thickest and hardest anodize available, suitable for automotive, aerospace, and heavy equipment parts.
