Aluminum
Aluminum is a lightweight, non-magnetic, silver-colored metal that can be formed into almost any shape. It can be rolled into thick plates for armored tanks or thin foil for wrappers. It can also be drawn into wire and made into cans.
Pure aluminum is soft and has limited strength. Small amounts of elements such as copper, magnesium, and zinc are often added to increase strength.
Aluminum is a comparatively new industrial metal that has been produced in commercial quantities for just over 100 years.
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 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 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 we provides are anodizing, powder coating, bead blast and plating. Each of these finishes has unique benefits. Choose the one best suits your needs!
| Photo | 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. |
