Aluminum CNC Machining Services

Aluminum stands out for its high machinability, durability, lightweight nature, and affordability, making it ideal for various parts across multiple industries.

What value of Choosing Aluminum for CNC Parts?

Aluminum’s low density, strong mechanical properties, high conductivity, and corrosion resistance make it a top machining choice. Popular alloys like 6061-T651, 7075-T651, and 2024-T351 strike the perfect balance of strength, machinability, and cost in CNC machining.

Key Value

  •  Excellent machinability
  •  High strength and hardness
  • Heat tolerance and corrosion resistance
  • Electrical conductivity
  • Overall versatility
  •  Low cost

Applications

Aluminum parts can be found everywhere, in a range of industries, especially automotive, aerospace, industrial equipment and machinery, and consumer and computer electronics.
• Automotive parts (light-weighting provides high strength-to-weight ratio)
• Housing, brackets, and other components for aerospace use that must support heavy load capacities but be light weight
• Fixtures, calipers, and a variety of other parts for industrial equipment
• Enclosures, panels, consoles, knobs, housing, and other applications for consumer and computer electronics

Aluminum Alloys for Machining

We offers several aluminum alloys in its long list of available manufacturing materials.
Aluminum 7075 T651 and T7: Benefits include high strength, hardness, low weight, corrosion resistance, and high heat tolerance.
Aluminum 2024 T3: This high-strength alloy offers a high strength-to-weight ratio and high corrosion resistance.
Aluminum 6061 T651: Though not as strong as other types of Aluminum, this alloy offers the best corrosion resistance and appearance after anodizing.

Finishing Options for CNC Machined Aluminum Parts

Anodizing is a popular finishing method, delivering robust corrosion resistance and improving the aesthetics of metal components. Techtunecnc offers three types of aluminum anodizing:
  • Type I – Chromic Acid Anodizing creates a thin yet durable coating, ideal for welded parts, assemblies, and as a primer before painting. It’s non-conductive, like other anodized surfaces.
  • Type II – Sulfuric Acid Anodizing provides a harder finish than Type I. It’s used in various applications, such as carabiner hooks, flashlight handles, motorcycle parts, and hydraulic valve bodies.
  • Type III – Hard Anodize (Hardcoat) is the thickest and hardest option. It has extensive applications in automotive, aerospace, heavy equipment, marine, general manufacturing, and military/law enforcement sectors.
