Available Grade for CNC Aluminum Parts

Aluminum, known for its lightweight nature, corrosion resistance, and strength, is extensively used in CNC machining. Depending on the specific application, various aluminum grades offer unique benefits. Here are some commonly used grades for CNC aluminum parts:

Aluminum 6061

A go-to choice for its versatility, 6061 offers excellent corrosion resistance, weldability, and medium strength. It's widely utilized for  camera lens mounts, couplings.

Aluminum 5083

Recognized for its excellent corrosion resistance, especially in marine environments, 5083 is often chosen for shipbuilding.

Aluminum 7071

Known for its high strength, 7075 is often used in aerospace and military applications. While not as weldable as 6061, its strength-to-weight ratio is impressive.

Aluminum 6063

Commonly used in architectural applications, 6063 offers good extrudability and a high-quality surface finish.

Aluminum 5052

With excellent formability, corrosion resistance, and weldability, 5052 is a favorite for sheet metal fabrication, including housings and enclosures.

Aluminum 2024

Primarily utilized in aerospace applications, this grade offers high strength and fatigue resistance but has poorer corrosion resistance.

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.
