A Guide to CNC Machined Aluminum and its Applications – DMTC

Aluminum alloy is a widely used and popular material. It completely changes industries such as aerospace and architecture. They are lightweight and strong, CNC machined aluminum has become the first choice for many manufacturers worldwide.


What is aluminum alloy?

Aluminum alloy is a metal that combines aluminum with other elements to create a material with unique performance. The aluminum adds copper, zinc, or magnesium, and the resulting combination creates a material with higher intensity and durability compared to pure aluminum. High-strength weight ratio. This makes it very suitable for aerospace engineering or automotive manufacturing. It can withstand harsh environmental conditions without degenerating over time due to its strong corrosion resistance.

Different types of aluminum alloy

Aluminum alloys are classified according to their chemical composition and elements. Different types of aluminum alloy include:

1. 1000 series:

These are pure aluminum and aluminum can reach more than 99%. There is excellent corrosion resistance, high thermal conductivity, and good processability of aluminum. Such as commonly used for car insulation boards, billboards, and machine parts with little force.

2. 2000 series:

These alloys contain copper as the main alloy element, which makes them stronger but poorer than other alloys. It is mainly used in aircraft structures, aerospace, engines, automotive bodies, ship hulls, and stress components.

3. 3000 series:

These alloys contain manganese, which can improve strength but reduce corrosion resistance. They are used for heat sinks, home appliances such as air conditioners, refrigerators, washing machines, and other fields.

4. 4000 series:

These are aluminum and silicon alloys with good welding performance but low strength. It belongs to construction materials, mechanical parts, and forging materials, there are low melting points and good corrosion resistance of aluminum.

5. 5000 series:

These alloys contain magnesium, which can improve strength, weldability, and corrosion resistance. It can be applied to the handle of the grass-cutting machine, the fuel tank catheter, the bulletproof coat, etc.

6. 6000 series:

These are thermal treatment alloys containing silicon and magnesium, with excellent molding, weldability, and mechanical processing. It is mainly used in construction, ships, rail vehicles, electrical electronics, durable consumer goods, and other fields.

7. 7000 series:

These are the strongest aluminum alloys. They use zinc as the main alloy element to provide excellent strength for the aircraft structure. There is excellent corrosion resistance, high heating, and good processing of these aluminum alloys. Application scope includes such as aircraft bearing components, landing gear, rockets, propellers, and aerial spacecraft.

Each type of aluminum alloy owns its unique characteristics. DMTC CNC machined aluminum can machine aluminum according to the needs of different industries. It can machine parts with complex shapes, and there is high precision, high efficiency, and other advantages of aluminum.

The advantages of CNC machined aluminum

1: It can reduce the number of workers in large quantities, and complicated parts of machining shapes do not require a complex workflow. If you want to change the shape and size of the parts, you only need to modify the parts processing program, which is suitable for the development and modification of new products.

2: The quality of machining is stable, the machining accuracy is high, and the machining requirements of the aircraft are met.

3: Multi-varieties and small batches of production efficiency are high, which can reduce the time for production preparation, machine tool adjustment, and process inspection, and reduce the cutting time because of the best cutting amount.

4: It can machine complex surfaces and even machine some unobservable processing places.

CNC machined aluminum with its high-precision,high-strength weight ratio, and super-strong corrosion resistance. They are widely used in aviation, automotive, medical, and other fields.

Applications of CNC machined aluminum

Aviation industry

High-intensity weight ratio, excellent ductility, and high corrosion resistance are the three important factors for aluminum alloy to become a commonly used alloy in the aviation industry. Because the intensity of aluminum is equivalent to steel, and the weight is far less than steel, the use of aluminum in aircraft manufacturing can make the aircraft weigh lighter, so that the aircraft can carry more goods and passengers, and also improves fuel efficiency. The highly resistant corrosionability of aluminum also helps ensure the safety of aircraft and passengers, which is one of its most basic guarantees in aviation travel. Therefore, CNC-machined aluminum is widely used in aircraft parts and aerospace components.

Shipping field

The lighter of the hull is the pursuit of the ancient construction of the ship, especially for freight ships. The lightweight and high-intensity aluminum is the best choice for building ships. In addition to tankers and large ships, CNC-machined aluminum is also used to build yachts, speedboats, and submarines. Most of them are also aluminum. Aluminum keels and masts can give rowing row a speed advantage in the game and increase the stimulation of leisure activities.

Medical field

Due to the advantages of high precision, CNC machined aluminum is widely used in the medical industry, such as main framework, medical equipment, medical stretcher bed framework, etc.

CNC-machined aluminum is not only used in aviation, ships, and the medical field. But also widely used in the building industry, and industrial production equipment, such as equipment hoods, automatic mechanical equipment, etc.
