6000 series aluminum alloys are mainly aluminum-magnesium-silicon alloys, which have good mechanical properties, weldability and corrosion resistance. This type of aluminum alloy can be strengthened by heat treatment and is very popular in construction, bridges, vehicle manufacturing and various applications that require good formability.
Chemical composition and characteristics
- Main alloying elements: 6000 series aluminum alloys use magnesium and silicon as the main alloying elements, such as 6061 alloy, which concentrates the advantages of 4000 series and 5000 series aluminum alloy.
- Characteristics:
Medium strength: 6000 series aluminum alloys have moderate strength and are suitable for a variety of structural parts.
Good corrosion resistance: It can show good corrosion resistance in a variety of environments.
Good welding performance: It is easy to carry out welding processing and the weld quality is high.
Good process performance: It is easy to extrude and can be processed into various complex shapes.
Good oxidation coloring performance: The surface can be anodized to improve the appearance and corrosion resistance.
Common 6000 series aluminum alloys include but are not limited to the following:
- 6061: This is a very versatile aluminum alloy with good mechanical properties, corrosion resistance, machinability and weldability. It is often used to manufacture aircraft parts, bridges, ship structures, pipelines, bridges and truck frames, etc.
- 6063: This alloy is mainly used in the construction industry, such as window frames, door frames, sign brackets and other decorative or structural profiles. It has a good surface finish and is suitable for anodizing.
- 6082: This alloy is suitable for applications requiring higher strength, such as bridge structures, towers, train carriages, etc. It is particularly popular in the European market.
The most commonly used 6000 series aluminum alloys are probably 6061 and 6063. 6061 aluminum is widely used due to its versatility and wide applicability; while 6063 aluminum is very common in the construction industry due to its excellent surface treatment characteristics and appropriate mechanical properties.
