Aluminum Properties

Aluminum, the twelfth-most common element of the universe, is a soft and ductile metal. It has a silvery gray outer appearance. The atomic number of this element is 13.

Aluminium is found in the 3rd period of the periodic table and is part of the 13th group. The chemical and physical properties of Aluminum make it very usable in diverse industries.

Let’s take a closer look into the characteristics of Aluminium.

anodizing aluminum parts

Corrosion ResistanceAluminum displays impressive resistance to corrosion, which means it doesn’t easily deteriorate when exposed to environmental elements.

This ability is triggered by a thin layer of Aluminum oxide that covers its outer surface, acting as a protective shield.

This layer of Aluminum oxide is generated as soon as the Aluminum surface comes into direct contact with the air.

In essence, it’s like the Aluminum forms its own natural armor to prevent damage from factors like moisture and oxidation.

Density – Aluminum has a lower density than most of the common metals like steel.

Electrical Conductivity – Its adeptness in conducting electricity makes it a preferred choice for electrical conduction purposes.

This metal finds application in high-voltage power lines, transformers, electric buses, and even socketed light bulbs, owing to its exceptional electrical conductivity.

Reflectivity – Aluminum boasts a remarkable attribute of bouncing back radiant energy across a comprehensive span of wavelengths.

Nearly 80% of light waves get reflected by it. This inherent reflectivity makes Aluminum a staple in illuminative apparatuses.

Efficient Heat Transfer – Aluminum conducts heat three times faster than steel.

This characteristic finds practical application in various fields.

For instance, it’s a popular choice in cookware, enabling even and rapid cooking.

Additionally, its prowess in heat conduction makes it a valuable component in air conditioning systems, ensuring effective temperature regulation.

Why Do Some Customized Aluminum Alloy Products Turn Black After Anodizing?

YIJIN Hardware reminds you that it may be that your aluminum machining material is not selected correctly, such as using aluminum alloy 7075.

As we all know, the oxidation effect of AL6061 is excellent, while the appearance of 6061 and 7075 materials is similar, and it is difficult to distinguish with the naked eye.

If there is no inspection before processing, and AL7075 is mistakenly processed as AL6061, the above problems will occur.

7075 aluminum is a forged alloy, which is synthesized from a variety of materials. During oxidation, due to the different chemical reactions of each material, the oxidation effect is uneven, and there are even some black spots. If the product is an appearance part, the effect will be great discounted.

Therefore, YIJIN Hardware reminds you again that aluminum machining materials, especially those with post-processing requirements, must ensure the authenticity of the raw materials.

As a CNC machining supplier, YIJIN Hardware is specially equipped with a spectrometer that can detect raw materials, so as to ensure the authenticity of the materials.

Overview of CNC Machining and Its Relevance in Modern Manufacturing

CNC machine uses computer programs to instruct different tools around various axes.

Computerized Numerical Control abbreviated as CNC describes a system that controls devices precisely through a computer program.

Computer numerically controlled machines can be a router, grinders, laser cutters, welders, milling machines, and so on.

Types of CNC Machining

  • CNC Milling Machine

This type of CNC machining is used for tapping, drilling, face and shoulder milling, etc.

These mills follow an X, Y, and Z system. A CNC milling machine is controlled by computer programs using letters and numbers.

  • Plasma Cutting Machine

Plasma cutting machines or plasma torches cut metal materials precisely.

This machine produces heat and speed by using compressed air gas and an electrical arc.

  • CNC Turning Machine

This type of programmed machine is used to execute complex designs.

When a manual machine can not cut the material meticulously, lathes or CNC turning machines become useful.

This machine has two axes called X and Z and the material is held on the rotating spindle of this machine to perform the function.

  • Electric Discharge Machine or EDM

EDM has two different models such as wire EDM and sinker EDM.

EDM uses electrodes to create electrical sparks for cutting and shaping materials.

When the gap between the two electrodes reduces, a current flows and removes specific parts of the workpiece.

In this way, EDM works using the spark machining or die sinking technique.

  • Water Jet Cutting Machines

The high-pressure water jets are used to cut hard materials like metal and stone.

Also, it is used on materials that can not tolerate high temperatures.

Relevance of CNC Machining in Modern Manufacturing

  • CNC machining contributes to the evolving mechanism of the manufacturing Industry. It helps in ensuring rapid prototyping of precise parts with detailed surface finishing.
  • CNC machining is used to make high-precision parts on large volumes.
