How Much Does It Cost to CNC Aluminum

Two important factors affecting the cost of CNC machining Aluminum are the complexity and size of the part and the type of Aluminum. LJZ is a professional China aluminium cnc parts supplier, and we would take full account into the cost details of CNC machining aluminum (including design, machinery, labor and raw material costs). Welcome to make an inquiry!

China Aluminum Machined Grade

Aluminium grades should be considered when choosing China aluminum machined technology. In recent years, due to its high strength-to-weight ratio, good corrosion resistance, good formability, and aesthetic appeal, aluminium die casting parts has increased its popularity. Since aluminum CNC parts are used in various industries, so selecting the most suitable China machining aluminum becomes more important.

As an expert aluminum machining supplier, we are familiar with the characteristics of each aluminum. Aluminium machining part supplier LJZ has always steeped ourselves in developing aluminum parts manufacturing. Below are some of the china aluminum machining part commonly used in our daily machining:

CNC Aluminium Cutting


Due to the soft and easy processing characteristics of aluminum profiles, special attention should be paid to deformation during CNC processing.

1. Select reasonable fixtures and control the fixture force.

Reasonable fixture and control force can reduce unnecessary positioning errors.  China aluminum parts supplier LJZ suggested that high-level engineers should be employed to carry out preliminary preparations such as fixture installation. Selecting special fixture tools and controlling the force during clamping can also improve the clamping method of aluminum profiles.

2. Select the appropriate tool and optimize it.

Because the aluminum profile is relatively soft, it is easy to deform during cutting. The material and geometric parameters of cutting tools have an important influence on the cutting force and heat of materials. We suggested that a larger chip space should be provided to ensure the normal operation of the tool, and the teeth number of the tool should be as small as possible.

3. Select a reasonable cutting amount and control the cutting speed.

The cutting speed should be controlled according to the hardness of the aluminum material, cutting state, material type, cutting depth, etc. This will effectively reduce the wear of the machine.

4. Use a special cutting emulsifier for aluminum alloy.

The professional cutting emulsifier can play the role of cooling, lubrication, cleaning, etc. in aluminum parts processing. This will be more helpful for producing aluminum parts.

Aluminum Alloys

Aluminum alloys are produced with so many grades that are mainly based on alloying elements and material properties. The naming convention uses four digits. The first digit of the number identifies the class or series of alloy(ex. 1xxx, 2xx.x, and 3xxx) , and the other three digits describe specific alloys, related hardening processes, and other useful information. Aluminum machined supplier LJZ will introduce you the following types:

2000 series: 2017, 2024, 2A12 etc

Features: It is called duralumin, has high strength, good cutting performance, can be heat treated. 

Applications: aircraft structures, aerospace, weapons, engines, pistons, automobile bodies, ship hulls and stress components, etc.

5000 series: common brands: 5052, 5083, 5754, 5182

Features: The main alloying element is Mg. It has good processing and molding performance, corrosion resistance, welding performance, fatigue strength and marine climate resistance.

Application: It is mainly used for building decoration, pressure vessels, ship structures and offshore facilities, aircraft fuel tanks, automobile fuel tanks, automobile gas reservoirs, containers, etc.

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

6000 series: 6061, 6063, 6082, etc.

Features: The main alloy elements are magnesium and silicon, with medium strength, good corrosion resistance, weldability and oxidation effect.

Example: 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.
