Aluminum Material Grade Avaibale:

Aluminum Grade




This grade is mainly contains magnesium and silicon, so it concentrates the advantages of the aluminum of 4000 series and 5000 Series,6061 is a cold-treated aluminium forging product, which is suitable for applications requiring high corrosion resistance and oxidation resistance. It has good usability, easy coating and good workability.



This is commonly known as "super hard aluminium",one of the highest strength aluminum alloys.Good mechanical properties and anodize reaction,but it is not weldable and has limited resistance to corrosion ,it is ideally used for highly stressed parts,, representative uses are aerospace, die processing, mechanical equipment, tooling fixtures, especially for manufacturing. Aircraft structures and other high-stress structures requiring high strength.



Commonly known as an architectural alloy. It is suitable for all kinds of industrial structural parts with high strength and corrosion resistance, such as trucks, tower buildings, ships, trams, railway vehicles, furniture, machinery parts, precision die manufacturing, electronic parts and precision instruments, SMT, PC board soldering tin carrier electronics, etc.



The main characteristics are low density, high tensile strength and high elongation.It can be easily drawn or formed into intricate shapes,Suitable for bending and welding.



The characteristics of aluminium2024 is high hardness,also the content of copper is the highest, about 3-5%. 2024 series aluminium bar most common used for Aviation material, which is not often used in conventional industry at present.

Surface Treatment:
Zinc/Nickel/Chrome plating,hot galvanized, painting, powder, coating, anodize, vacuum plating, polishing, 

electrolytic polishing, steel blue, sank without electricity nickel, silver-plated, gold-plated, and so on.

(with the technical drawing taking precedence).

3. All parts have had sharp edges and burrs removed.                                

4. All thread holes are accounted for and tapped as per the technical drawing

(where applicable as indicated on the Purchase Order).

5. All tolerances are within specification as per the technical drawing  

(where applicable as indicated on the Purchase Order).

6. All part surface finishes have been applied and are consistent and free of any chips or scratches (where applicable as indicated on the Purchase Order).

7. Relevant QA/QC documentation is included with the order  

(where applicable as indicated on the Purchase Order)

8. All parts are correctly packed to ensure parts are not damaged while in transit

Q:How much does it cost to CNC aluminum?

A:The cost of CNC machining aluminum is mainly determined by the size and structure of the product. If you want to know the specific cost of your product, please contact us for a quick quotation now.

Q:How does CNC machining work?

A:CNC machining refers to machining performed with CNC machining tools. The CNC index-controlled machine tool is programmed and controlled by the CNC machining language. The CNC machining G code language tells the CNC machine tool what kind of Cartesian position coordinates the tool uses, and controls the tool feed speed and spindle speed, as well as tool converters, coolant, etc. CNC machining has great advantages over manual machining. For example, the parts produced by CNC machining are very accurate and repeatable; CNC machining can produce parts with complex shapes that cannot be manually processed. CNC machining technology has been widely promoted. Most machining workshops have CNC machining capabilities. The most common CNC machining methods in typical machining workshops include CNC milling, CNC lathe, and CNC EDM wire cutting (EDM wire cutting).

Q:How can you tell the difference between 6061 and 7075 aluminum?

A:1)The alloy composition is different.The 7075 aluminum plate is a super-hard aluminum plate, and the hardness is much higher than 6061.
2)Different applications, 6061 alloy aluminum plate requires a variety of industrial structures with certain strength, weldability and high corrosion resistance, such as the manufacture of pipes for trucks, tower buildings, ships, trams, furniture, mechanical parts, precision machining, etc. Rods, profiles, plates. 7075 aluminum plates are used to manufacture aircraft structures and other high-stress structural parts and molds that require high strength and strong corrosion resistance.
3)The price is different, and the price of 7075 aluminum plate is much higher than that of 6061 aluminum plate under conventional specifications.

Q:What is a 5 axis CNC machine?

A:5 Axis CNC Machining refers to the x, y, and z movement axes plus any two rotation axes. Compared with the common three-axis (x, y, z three degrees of freedom) machining, five-axis machining refers to the processing of parts with more complex geometric shapes, which requires the machining tool to be positioned and connected in five degrees of freedom. The five-axis machine tool can process different sides of the workpiece without changing the position of the workpiece on the machine tool, which can greatly improve the processing efficiency of the prismatic parts.
