DNV Approved Aluminum Sheet Metal for Fishing Boat
6 series aluminum alloy is an Al-Mg-Si alloy with magnesium and silicon as the main alloying elements, which can be strengthened after heat treatment. Its main aluminum sheet metal grades are 6061, 6063, 6082, 6016, 6101, etc. Compared with 2 series and 7 series, 6 series aluminum alloy has moderate strength, but its Mg and Si alloys have strong corrosion resistance, good oxidation effect, good welding performance, good formability and process performance.
1. 6061 aluminum alloy
6061 aluminum alloy is the most well-known and widely used 6xxx aluminum alloy grade. It has good mechanical properties and can be further strengthened by heat treatment. It also has good corrosion resistance and welding performance.
Main performance:
Tensile strength: 290MPa~310MPa
Yield strength: 240MPa~270MPa
Hardness: 95HB~100HB
6061 aluminum alloy is widely used in the manufacture of aircraft parts, automobile parts, ship structures, etc. It is suitable for occasions requiring high strength and corrosion resistance, especially in the transportation industry, and is favored for its high strength and lightweight characteristics.
2. 6063 aluminum alloy
6063 aluminum alloy is mainly used in the field of architectural aluminum profiles, and its formability and surface treatment performance are excellent. Compared with 6061, 6063 has a slightly lower strength, but has better extrudability and surface finish, so it is often used in door and window frames, building curtain walls, etc.
Main performance:
Tensile strength: 190MPa~210MPa
Yield strength: 150MPa~180MPa
Hardness: 75HB~85HB
6063 aluminum alloy is characterized by simple processing and low cost, and is suitable for architectural aluminum profiles that need to be mass-produced. Its good extrusion performance makes it particularly popular in the construction industry.
3. 6082 aluminum alloy
It is a relatively high-strength 6 series aluminum alloy, mainly used for structural parts and engineering machinery parts with higher requirements. Compared with 6061, 6082 has higher strength, but its machinability is slightly inferior.
Main properties:
Tensile strength: 310MPa~340MPa
Yield strength: 260MPa~290MPa
Hardness: 100HB~110HB
6082 aluminum alloy is often used in heavy structural parts, freight vehicles, shipbuilding and other fields, especially in occasions requiring higher strength and durability.
Features of 6xxx aluminum alloys
Through the above introduction of several common 6 series aluminum alloys, we can summarize some of their common characteristics:
Moderate strength: The strength of 6 series aluminum alloys is slightly lower than that of other series aluminum alloys (such as 7 series aluminum alloys), but it can be significantly improved after heat treatment to meet the needs of most industrial applications.
Good corrosion resistance: The addition of magnesium and silicon makes the 6 series aluminum alloy very good in corrosion resistance, especially suitable for humid, acid-base environments.
Excellent processing performance: 6 series aluminum alloy has good processability and can be easily processed whether it is extrusion, welding or surface treatment (such as anodizing).
Strong heat treatability: After heat treatment, the performance of 6 series aluminum alloy will be significantly improved, which makes it widely used in structural parts, load-bearing parts and other fields.
