With the rapid development of science, technology and industrial economy in recent years, aluminum alloys have been widely used in aviation, aerospace, automobiles, machinery manufacturing, shipbuilding and chemical industries. It is the most widely used non-ferrous metal structural material in the industry.

Due to its superior mechanical properties, physical properties and corrosion resistance, aluminum alloy is one of the most commonly used materials for machining. Commonly used aluminum alloy machining materials generally fall into the following two categories: Customers in the aviation industry use aluminum:

2000 series aluminum alloys, such as: 2024, 2A16 (LY16), 2A02 (LY6) are characterized by high hardness, among which the copper content is the highest, about 3-5%. 7000 series aluminum alloys, such as: 7075, which is aluminum Magnesium-zinc-copper alloy is a heat-treatable alloy. It is a superhard aluminum alloy and has good wear resistance and good weldability. Aluminum used by customers in other general industries:

5000 series aluminum alloys, such as 5052 and 5083, the main element is magnesium, and the magnesium content is between 3-5%. It can also be called aluminum-magnesium alloy. The main features are low density, high tensile strength, high elongation and good fatigue strength.

6000 series aluminum alloys, such as 6061, mainly contain magnesium and silicon, and are suitable for applications requiring high corrosion resistance and oxidation resistance. Good workability, easy coating and good processability.

Aluminum alloy machined products are used in a wide range of applications, such as cavities, casings, heat sinks, internal small parts, etc.
