Comparison of the cost of CNC machining aluminum profiles

Price has always been an important consideration in material selection, especially in large production. Here are the average prices of the four aluminum models:

  • 6061 Aluminum alloy: $2.5-3.50 / lb.
  • 7075 aluminum alloy: $4- $5 / lb.
    -2024 aluminum alloy: $3- $4 / lb.
  • 5083 aluminum alloy: $5- $6 / lb.

Cost analysis of traditional machining and CNC machining of aluminum profile

The traditional machining method is mainly to use human or mechanical directly machining aluminum profile. CNC machining is through the computer to the aluminum machining command control.

First, let’s look at the cost analysis of traditional machining methods. Traditional machining method has high labor cost for aluminum production process, which requires hiring workers, machinery and equipment, and the cost of these factors is also very significant, so the cost of traditional machining method is relatively high.

In contrast, CNC machining is more efficient and sustainable in the machining of aluminum. CNC machining equipment can last for several days, or even up to a week or more. In addition, CNC technology can be through its unique computer control, so that aluminum profiles can be more accurate machining. This can make the final output of aluminum profile more perfect and accurate. In other words, CNC machining has higher production efficiency and lower cost than traditional machining.

In the final cost analysis, we found that CNC machining aluminum profiles has more advantages than traditional machining methods in both labor cost and material cost. In addition, machining aluminum profiles through CNC machining has more advantages in precision. Therefore, in the production of aluminum profiles, we recommend the use of CNC machining.

If you think CNC machining of aluminum is more suitable for your plant or use scenario, consider a better CNC machining equipment. If you have any questions or need to consult, please contact us. We will provide you with the best technical support.

Cnc machining aluminum model advantages and disadvantages

It is important to know the advantages and disadvantages of the material you want to use before proceeding to CNC machining aluminum. This helps you select the best materials for your project, improve product quality and reduce costs. Let’s take a look at the pros and cons of each type of aluminum.

6061: This aluminum is very common in CNC machining and has a wide range of uses. Although the 6061 has good toughness and strength, it has the disadvantage that it is not easy to weld and has a high corrosion rate with other metals. The most suitable applications are those requiring high strength and durability.

7075: This is a radical high strength aluminum for durable and demanding high strength projects. However, compared with 6061, 7075 is more difficult to process and is more prone to cracking and microcracks. If your project needs high performance, then 7075 is a good choice.

2024: This aluminum is very lightweight and is used for projects that require light weight. However, 2024 is not as strong as 6061 and 7075 and is more brittle. Best suited for applications in medium load and very light applications.

2024-T3: This aluminum is stronger than 2024 and has higher corrosion resistance. Although the machining difficulty is not as good as 7075, it is relatively stable. This is a very suitable material for use in aviation.

5083-H321: This aluminum is resistant to corrosion and water and can be used in Marine and other saline environments. This is a very good choice of material that can be used to make vessels.

6061-T6: This aluminum has higher strength and better corrosion resistance than 6061. It is relatively stable in structure, but it requires higher production cost due to its poor weldability.

7075-T6: This is one of the most commonly used high-strength aluminum, showing excellent performance while also having strong corrosion resistance. Because of its light weight, high strength, hardness and other characteristics, can be used to manufacture a variety of products. However, it is also more difficult to process than other aluminum. Therefore, if you encounter problems in machining, it is recommended to consult professional processing manufacturers.

In general, different types of aluminum have their own unique advantages and characteristics, the selection of appropriate aluminum materials will help to improve product quality and reduce costs. Therefore, the selection of aluminum needs to consider the use of environment and machining methods. The trade-off between cost, strength and corrosion resistance is very important. Please remember to carefully weigh each factor in the selection to make your machining results better.
