Best Aluminum for Machining

6061 Aluminum

  • Features: Excellent balance of strength, machinability, and weldability.
  • Advantages: Versatile for a wide range of applications, offering good corrosion resistance and finishability.
  • Considerations: While highly versatile, it may not be suitable for more demanding, high-strength applications.

7075 Aluminum

  • Features: High strength-to-weight ratio, better for high-stress applications.
  • Advantages: Ideal for aerospace and other industries where superior strength is critical.
  • Considerations: Less weldable and more costly than other aluminum alloys like 6061.

2024 Aluminum

  • Features: Known for high strength and good fatigue resistance.
  • Advantages: Particularly suited for applications that endure periodic stress, like in aerospace components.
  • Considerations: Not as corrosion-resistant as other alloys, often requiring protective coatings.

6 Surface Finishes for CNC Aluminum Parts

Several surface finishes are commonly used for CNC machined aluminum parts, each providing different aesthetic and functional benefits:

Anodizing
A process that electrochemically converts the aluminum surface into a durable, corrosion-resistant, anodic oxide finish. This not only enhances durability but also allows for color customization.
Bead Blasting
Involves propelling fine beads at high pressure to achieve a uniform, non-reflective, matte finish. This technique is particularly effective in obscuring machining marks and improving surface consistency.
Powder Coating
Applies a polymer resin, mixed with color pigments and other additives, which is then cured to form a protective and decorative layer. This method offers enhanced resistance to corrosion, impact, and wear.
Electropolishing
An electrochemical process that removes surface material, resulting in a smoothed, polished, and brightened finish. This also improves corrosion resistance and cleans the surface of impurities.
Brushed Finish
Produces a unidirectional satin finish through abrasive brushing, which enhances the visual appeal and reduces the visibility of machining marks.
Polishing
A mechanical process that creates a highly reflective and smooth surface. It’s particularly desirable for parts that require a mirror-like aesthetic.
