Aluminum Alloys for Machining

When it comes to CNC machining, the choice of material significantly impacts the final product's quality, functionality, and applicability. Aluminum alloys, known for their excellent machinability, strength-to-weight ratio, and corrosion resistance, are among the most favored materials in precision machining projects.

6061 Aluminum Alloy

  • Characteristics: 6061 is a versatile, heat-treatable alloy with good corrosion resistance. It combines magnesium and silicon, which makes it preferable for applications requiring toughness and light weight.
  • Applications: Widely used in automotive parts, aircraft and marine fittings, electronic components, and construction.

7075 Aluminum Alloy

  • Characteristics: Known for its high strength, 7075 is a zinc alloy that offers one of the highest strength compositions available for aluminum alloys. It is not as resistant to corrosion as other alloys but stands out for its toughness.
  • Applications: Commonly used in aerospace components, defense machinery, and high-stress applications where strength is crucial.

6063 Aluminum Alloy

  • Characteristics: 6063 is often referred to as an architectural alloy, offering a good surface finish, high corrosion resistance, and is easily welded.
  • Applications: Used for architectural applications, door frames, windows, roofs, and sign frames.

5052 Aluminum Alloy

  • Characteristics: This alloy has excellent corrosion resistance, making it suitable for marine environments. It's also non-heat treatable but can be welded and formed easily.
  • Applications: Used in sheet metal work, marine environments, appliances, and fencing.

2024 Aluminum Alloy

  • Characteristics: 2024 aluminum alloy is known for its high strength and fatigue resistance but has lower corrosion resistance. It is often used with a coating or cladding to protect it from oxidation.
  • Applications: Primarily used in aircraft structures, rivets, truck wheels, and many other structural applications requiring a strong material.

6082 Aluminum Alloy

  • Characteristics: Similar to 6061 but with slightly higher strength. It has good weldability, resistance to corrosion, and is heat treatable.
  • Applications: Often used in structural applications, bridges, cranes, trusses, and other high-stress structures.

Anodizing Options for CNC Machined Aluminum Parts

Anodizing is a popular surface finishing technique for aluminum parts, enhancing corrosion resistance, surface hardness, and wear resistance, while also allowing for color customization. This electrochemical process converts the metal surface into a durable, corrosion-resistant, anodic oxide finish.

Type II Anodizing (Conventional Anodizing)

Type II Anodizing (Conventional Anodizing)

  • Characteristics: Produces a thin oxide layer that can be dyed in various colors, enhancing aesthetic appeal and corrosion resistance. The thickness of the anodic coating typically ranges from 0.5 to 25 micrometers.
  • Applications: Ideal for cosmetic applications where visual appeal is a priority, including consumer electronics, automotive trim, and decorative items.

Type III Anodizing (Hardcoat Anodizing)

  • Characteristics: Generates a thicker oxide layer (25 to 125 micrometers), significantly increasing abrasion resistance and durability. The finish is more wear-resistant and provides better insulation.
  • Applications: Suited for industrial and mechanical parts exposed to harsh environments or where increased wear resistance is required, such as gears, valves, and aerospace components.

Surface Finish of Machined Aluminum Parts

The ability to achieve a precise surface quality on machined aluminum components is frequently vital to the success of any mechanical system or application. It has an impact on the visual look, durability, and protective features of machined items, as well as their cost-effectiveness.

As-machined aluminum parts

Machined finishes are surface treatments applied to aluminum alloys by grinding and polishing, which are methods of abrasion. This grinding process removes the surface layer of the metal to create the desired texture.

Sandblasted machined aluminum parts
Sand blasting

Sandblasting gives the machined item a uniform matte or satin finish, which eliminates signs of machining and gives a smoother surface. It works by blasting the part with small glass beads using a pressurized air gun.

Anodizing is a direct electrochemical technique that results in the formation of a protective layer of aluminum oxide on the surface of the metal, which has good insulating, aesthetic and wear resistance properties.

Nickel Plated Machined Aluminum Parts

After plating various metals on the surface of aluminum products, the physical or chemical properties of the surface can be obviously improved. Common types of aluminum plating are nickel plating, silver plating, zinc plating, chrome plating, etc.

Powder coated machined aluminum parts
Powder Coating

Powder coating is the application of paint that is devoid of solvents. The mixture is applied to the metal with a spray cannon to create a smooth covering. Matte or glossy coatings mimic the ornamental look of paint while being more durable.

Brushing Machined Aluminum Part
Metal Brushing

Metal brushing is the process of constantly scraping lines with sandpaper in the machined areas of the surface of the metal part to be treated. This process shows every trace of the fine lines, giving the metal a shine.
