Aluminum alloy is an aluminum-based material made by adding a certain amount of other alloying elements. This type of alloying element usually refers to copper, silicon, magnesium, zinc, manganese, etc. Aluminum alloys are lightweight metal materials with basic properties similar to aluminum but also properties brought by added elements.
Therefore, aluminum alloys have excellent properties. For example, high strength, high pressure bearing capacity, excellent plasticity, excellent electrical and thermal properties, excellent corrosion resistance, etc.
Aluminum alloys are widely used in many industries because of the above excellent properties, including but limited to aerospace, transportation, construction industry, mechanical and electrical products, light industrial products, and daily necessities.

The difference between aluminum alloy and pure aluminum is mainly reflected in the following aspects:
Aluminum alloys are an alloy metal material. They mainly use aluminum as the main material but contain other metal components. The purity of aluminum alloys is not high. However the purity of pure aluminum is 99.7%, and they contain almost no other impurities.
Aluminum alloy has strong toughness and is not easily deformed, but its corrosion resistance is relatively poor. In contrast, pure aluminum has extremely strong corrosion resistance and high purity, so its toughness is relatively poor and it is easy to deform.
Aluminum alloys are currently widely used in many industries. For example, the aerospace industry, chemical industry, marine industry, automotive industry, etc.
The application range of pure aluminum materials is relatively narrow.
The price of aluminum alloy is relatively high, while the price of pure aluminum is relatively low.
Aluminum alloy has good corrosion resistance. When aluminum alloys come into contact with air, a dense oxide film will form on the surface. This oxide film can resist corrosion and play a protective role, so its corrosion resistance is relatively excellent.
The tensile strength of pure aluminum is one-fifth that of mild steel. However, after aluminum alloys are strengthened by heat treatment and alloying, their strength is greatly increased.
Lightweight and easy to transport
Aluminum alloys have excellent machinability properties. Whether it is extrusion, secondary processing, or bending processing, it is relatively easy.
Aluminum alloy has good sealing performance and high processing accuracy.
Aluminum alloy materials can be recycled and are beneficial to environmental protection.
Aluminum alloy materials can be made into various complex profiles through the extrusion process.
Aluminum alloy materials are not easily affected by air pollution and can maintain their inherent color and luster for a long time.
Aluminum alloys can be divided into two major categories if distinguished by processing methods. The first type is deformed aluminum alloy, and the second type is cast aluminum alloy. These two types of materials are further divided into heat-treatable and non-heat-treatable materials.
First of all, the grade of deformed aluminum alloy is represented by a four-digit number, which includes the proportion of alloy components. The 4-digit number after the dash represents the type of heat treatment, such as "6061-T6".
Secondly, cast aluminum alloys use a 4 to 5-digit number with a decimal point. The numbers in the hundreds of digits represent alloy elements, and the decimal point is used to identify whether it is a casting or an aluminum ingot.
