Metal prototyping is also important to many companies, from aerospace to electronic technology products, as effective metal prototyping can lead to better finished products.

Currently, the common processes used for metal prototyping are CNC machining, casting, sheet metal forming and 3D printing, and the common materials used are aluminum and steel. Among them, aluminum is most widely used for the following main reasons.cnc aluminum parts

1. Excellent processability

Aluminum has excellent processability, which is calculated by dividing the current material processing rate by the finished material processing rate.

In addition, aluminum alloy has a wide range of machining processes, such as CNC turning, CNC milling, grinding, polishing, honing, drilling and tapping, EDM, EDM electrochemical machining, grooving, etc.aluminum t profile

2. Extremely high precision and surface finish.

CNC machining of aluminum alloy workpieces we can achieve an optimum surface finish by obtaining an optimum surface finish while achieving precise management of control system tolerances. It is possible to obtain a mirror-like surface by oneself if it is not operated by polishing techniques. Aluminum can be machined to a maximum tolerance of IT8-7 and a surface finish of RA 1.25 µm.led panel aluminum frame

3. Corrosion resistance

Aluminum is uniquely resistant to corrosion. Electrical resistance can form a thin oxide layer on the surface of aluminum as little as 1 mm thick. It serves to protect the metal from harmful external substances. As a result, there is no need for additional paints or coatings on the parts to prevent rusting.

4. Powerful weight-strength ratio

Aluminum alloy is three times lighter than steel, making it very lightweight. At the same time, some aluminum alloys have been improved to provide good strength.

5. Non-magnetic alloy

Aluminum does not react with magnets and can be used to make parts that require resistance to magnetic fields. Also, aluminum is cheaper than other similar alloys.

6. Medical applications

Many people think that aluminum alloys are seldom used for medical treatment, but some aluminum alloys can be used for medical treatment.

7. High conductivity

Copper can often be used for building electrical control components and wiring because of a good electrical conductivity. However, it is soft, expensive and has poor corrosion resistance. Although the conductivity of aluminum is slightly worse than copper, but it is also considered to be very good conductive material material, but also effectively overcome some of the main disadvantages of copper. Therefore, aluminum processing can be used for electric prototypes, especially in the manufacture of technically complex electrodes, CNC machining aluminum parts.

8. Easy to recycle

At present, environmental protection is also a factor that must be considered in industrial production. Although many materials can be recycled and processed for reuse, but the corresponding cost is high. Aluminum alloy can be used again simply by re-melting, the cost is relatively low.
