Available Aluminum Alloys for CNC Machining

Common aluminum alloys for CNC milling or turning include 6061, 7075, 6082, and 5083-H111. 6061 offers corrosion resistance and weldability; 7075 boasts high strength; 6082 provides balanced properties with good machinability; and 5083-H111, with exceptional seawater resistance, is perfect for marine and transport applications.

Each alloy has unique benefits that make them well-suited for different CNC machining applications.

Aluminum 6061-T6

Aluminum 6061-T6 is a heat-treatable alloy boasting high strength and corrosion resistance. Contains magnesium and silicon as main alloying elements. T6 signifies solution heat-treated and artificially aged. Ideal for aerospace, automotive, and structural uses. Known for its weldability and durability.

Aluminum 7075-T6

Aluminum 7075 is prized for its high strength and hardness, making it an ideal choice for products that must withstand high loads or extensive wear and tear. 7075 aluminum is also low in weight and resistant to corrosion. Anodizing can further improve the corrosion resistance of 7075 aluminum and give it an attractive appearance.

Aluminum 5083-H111

Aluminum 5083 H111 is a non-heat-treatable, strain hardened and thermally stabilized aluminum alloy with excellent corrosion resistance, especially to seawater. It has moderate strength, good weldability and ductility making it well suited for marine applications, unfired pressure vessels, cryogenic storage tanks, and transportation equipment.

Aluminum 6082

Aluminum 6082 is a medium-strength alloy with excellent corrosion resistance. It contains magnesium and silicon as main alloying components. Often used in highly stressed applications, it’s weldable and exhibits good formability. Popular in structural engineering, especially in bridges and transport vehicles.

CNC Machined Aluminum 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

Surface Finishes For CNC Machined Aluminum Parts

Many types of surface finishes can be applied to CNC machined aluminum parts. The most common finishes AT-Machining provides are anodizing, powder coating, bead blast and plating. Each of these finishes has unique benefits. Choose the one best suits your needs!

	Name	Description
	As machined	The machined aluminum parts are left with visible tool marks and potentially sharp edges and burrs, which can be removed upon request.
	Bead Blasted	Give the machined parts a smooth and uniform matte surface finish, thereby removing tool marks.
	Polishing	Creating a smooth and shiny surface by manually polishing in multiple directions or by applying a chemical polish treatment.
	Anodizing	Type II (Anodizing color or clear) or Type III (Anodizing hard coat) Anodizing does not cover tool marks unless bead blasted beforehand.
	Chromate Conversion Coating	Increase the part's corrosion resistance while retaining its conductivity. RoHS compliant.
	Decorative Chrome Plating	Enhance aesthetics and durability of the cnc aluminum components.
	Powder Coat	Applying powdered paint to the components and then baking it in an oven, which results in a stronger, more wear- and corrosion-resistant layer that is more durable than traditional painting methods.
