Aluminium alloy is also processed by die casting for structures of various industrial products. Sibai produces variety Aluminium CNC components and also provides aluminium die casting parts.

Types of Aluminium Alloys Machining Processes

Aluminium Machining Grades

  • 1100 Aluminium Alloy

    Aluminum 1100 alloy is ordinary industrial pure aluminum with an aluminum content of 99.0%.

    It can be hardened by cold working, but not by heat treatment. Low strength, but good ductility, formability, weldability and corrosion resistance. It may be suitable for applications that require bending, spinning, drawing, stamping and roll forming.

  • 2024 Aluminium Alloy

    Aluminum 2024 alloy is a kind of high-strength hard aluminum, belonging to the aluminum alloy of Al-Cu-Mg series. Due to its high strength to weight ratio, it is widely used in aerospace applications. It is mainly used to make various high-load parts and components. It can be strengthened by heat treatment and has medium plasticity in quenched and just-quenched states.

  • 5052 Aluminium Alloy

    Aluminum 5052 alloy belongs to Al-Mg alloy, which is widely used, especially the construction industry, which highly inquires this alloy. It is one of the most promising alloys. Good corrosion resistance, excellent weldability, good cold workability, and moderate strength. It is commonly used in a multitude of engineering applications.

  • 5083 Aluminium Alloy

    Aluminum 5083 alloy is a high magnesium alloy with good strength, corrosion resistance and machinability among non-heat treatable alloys. It is highly resistant to attack by seawater and industrial chemicals. It is not recommended for use in temperatures in excess of 65 °C.

  • 6061 Aluminium Alloy

    Aluminum 6061 is a heat-treated reinforced alloy with good formability, weldability, machinability, and moderate strength, which can maintain good operability after annealing. It is one of the most common alloys for general purpose use. 6061 aluminum alloy can be heat treated.

  • 7075 Aluminium Alloy

    Aluminum 7075 alloy is a cold-treated forged alloy with high strength, far superior to mild steel. 7075 is one of the strongest alloys commercially available. 7075 aluminum alloy has a compact structure and strong corrosion resistance, which is the best for aviation and marine plates. Normal corrosion resistance, good mechanical properties and anodic reaction.

  • 6063 Aluminium Alloy

    Aluminum 6063 alloy is widely used in the frame of building aluminum doors and windows and curtain walls. It is a common aluminum alloy model. It allows complex shapes to be formed with very smooth surfaces fit for anodizing.

  • 6082 Aluminium Alloy

    Aluminum 6082 alloy belongs to the 6th series (Al-Mg-Si) alloy aluminum plate, which is an aluminum alloy plate that can be strengthened by heat treatment. It has medium strength, good welding performance and corrosion resistance. It is mainly used in transportation and structural engineering industry.


An aluminium alloy  is an alloy in which aluminium is the predominant metal.  There are two principal classifications, namely casting alloys and wrought alloys, both of which are further subdivided into the categories heat-treatable and non-heat-treatable.

Machining Processes Available For Aluminium Alloys

Machining Processes Available For Aluminium Alloys

Aluminium is the most common material in the machining. About 60% of Sibai's machining is to machine the material of Aluminium. Sibai has equipped with advanced fast speed swiss automatic lathe and 5 Axis machiningcenters to produce complicated designed and curve designed components. In addition, we also offer secondary processing, surface finishings as well as assembly of finished products, which can provide customers the best one-stop service by Sibai. 

Most of the machined CNC components request anodizing finish or sandblasted anodizing finish to realise the surface protection and color appearance.
