Aluminum


Aluminum alloy materials are favored by engineers in various industries, and it is commonly used material in CNC machining due to its high machinability. Aluminum can be quickly and easily cut by machine tools, and deforms less which leads to higher accuracy. Aluminum is widely used to create specified precision parts in various industries today.


China CNC Aluminum Benefits

Due to the good fluidity and plasticity of aluminum alloy, casting on die casting machine, aluminum parts machining die casting machine CNC machining processing a variety of complex shapes, which can produce higher precision and surface quality. To a large extent, the castings and China aluminum machining services or custom China aluminium machining part are great, and also save electricity, metal materials, and labor costs. Choose China aluminum machining manufacturers, We can offer you cheap custom cost of machining aluminum.


China Machining Aluminum Parts Surface Finishes

CNC aluminum parts are widely popular in almost every industry due to its excellent machinability. Another benefit of aluminum machined parts is that there are many options for its surface treatment, such as:

  • Anodizing

  • Powder spraying

  • Painting

  • Polishing

  • Sandblasting

  • Laser engraving

  • And many more


China Aluminum Machined Grade

Aluminum CNC parts are used in various industries, so choosing the most suitable China machining aluminum is very important. As an expert aluminum machining supplier, we are familiar with the characteristics of each aluminum. Below are some of the aluminum commonly used in our daily machining:


  • AL 2000 series

2011, 2014 2017 2024 


  • AL 3000 series

3004 3018 3104 3105 3105 3040


  • AL 4000 series

4032 4043


  • AL 5000 series

5005 5052 5082 5083


  • AL 6000 series

machining 6061 aluminum, 6063 6040


  • AL 7000 series

7072, machining 7075 aluminum


Aluminum Alloys

  • AL5052 has good seawater corrosion resistance and excellent machinability. Often used in marine environments, such as ship hulls, gangways. and other marine equipment, etc.


  • AL6061 has good weldability, formability and machinability. At the same time, it has medium strength and maintains good operability after annealing. Mainly used in aerospace fixtures, electrical fixtures, communications, etc.


  • AL7075 is one of the strongest commercial alloys. It has strong corrosion resistance and is the best for aviation and marine plates. It's ideal for highly stressed parts. Mainly used in aerospace industry.


Machining 7075 aluminum and machining 6061 aluminum, Which One Should You Choose for Your Aluminum Parts Machining


The main differences between machining 7075 aluminum and machining 6061 aluminum are the following properties.


Aluminum series and chemical composition:machining 6061 aluminum has a higher silicon content, while machining 7075 aluminum has a higher zinc content. When looking at the exact range of data for both aluminum, it can also be seen that both aluminum contain a significant amount of magnesium, although machining 7075 aluminum has a slightly higher magnesium content.


Mechanical Properties: When looking at the two aluminum in the -T6 heat treatment condition, some significant differences can be seen. The first is that the tensile strength of 7075-T6 is almost twice that of 6061-T6. The second is that the shear strength of 7075-T6 is approximately 1.5 times that of 6061-T6.


Fabrication Considerations: The lower hardness and tensile strength make machining 6061 aluminum easier to manufacture than machining 7075 aluminum. machining 6061 aluminum is weldable, while machining 7075 aluminum is generally considered to be non-weldable.


Application Areas: Both aluminum are used for bicycle parts, aerospace parts and architectural structures. However, their specific uses in these areas differ.


Quality Assurance for CNC Aluminum Part


From the outside, different aluminum are indistinguishable by the naked eyes which greatly affects the quality of products. In order to ensure the authenticity of raw materials, LJZ is equipped with spectrometer which is able to strictly detect raw materials with testing report. Moreover, we also provide SGS material certificate according to customer's requirements.

Aluminium Machining Service Processes

  • Swiss CNC Machining is a modern precision manufacturing process, which can produce very small parts quickly with tight tolerances and extreme accuracy. LJZ has 100+ state of the art Swiss turns and this helps us to produce million of swiss turned parts of in every month.


  • Precision CNC machining utilizes various tools and equipment such as CNC Swiss machines, 3,4,5 axis machines, horizontal and vertical milling, CNC turning technologies  to remove raw materials to manufacture certain parts or assemblies.  Which are suitable for machining complex aluminum parts with tight tolerances.


  • EDM uses the electric discharge generated between two electrodes to remove material from the workpiece. Although it can process any conductive materials such as aluminum and stainless steel. But because of cost, it's often used to machine harder and more difficult materials.
