Aluminum Grade For CNC Machining

When it comes to machining, picking the right grade of aluminum is crucial. It's important to choose a type of aluminum that can withstand the pressures of your particular manufacturing process and deliver the desired results time after time. Various grades provide different levels of hardness, strength, formability, and weldability—all extremely important when machining aluminum parts for any project.

Aluminum 2024

The 2024 aluminum alloy is a high-strength hard aluminum alloy with a high hardness and outstanding wear resistance. It is primarily utilized in the manufacture of different high-load parts and components, and it may be heat treated and reinforced.

Aluminum 5052

5052 aluminum has good forming and processing properties, as well as corrosion resistance, weldability and medium strength, and can be used to manufacture aircraft fuel tanks, ship sheet metal parts, street light brackets, electrical housings, etc.

Aluminum 6061

Aluminum 6061 is the grade of aluminum most often used in CNC machining. It has very good machining quality, corrosion resistance, high toughness, no deformation after machining, and good anodizing.

Aluminum 6063

Aluminum 6063 has strong mechanical properties, can be heat treated, can be formed into complex shapes, and has a very smooth surface that is ideal for anodizing. It is used in architectural decorative profiles and pipes, such as aluminum housings and aluminum radiators.


Aluminum 6082

Aluminum 6082 is an aluminum alloy sheet that can be strengthened by heat treatment, with medium strength and good welding performance, and corrosion resistance, mainly used in the transportation and structural engineering industry. 

Aluminum 7075

7075 aluminum is extensively used in high-stress technical applications such as aviation and automobile components, as well as sports equipment. 7075 aluminum has a high strength-to-weight ratio, making it appropriate for a wide range of applications.


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.


Color Anodizing machined aluminum parts

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.


Machined Aluminum Applications

Wide range of applications

Machined aluminum components are incredibly flexible and may be used in a wide range of industries. Because of their unusual mix of strength and light weight, they are especially popular in the automobile, aerospace, industrial equipment and machinery, and consumer and computer electronics industries. Machined aluminum applications are also cost-effective due to simple machining methods and shorter lead times.

Aerospace Industry

Machined aluminum for lightweight, high-strength aircraft components.

Electronics Manufacturing

Aluminum casings for optimal heat dissipation and electrical conductivity.

Automotive Sector

Fuel-efficient, corrosion-resistant aluminum parts for vehicle performance.

Robotics Applications
