Can marine grade aluminum 6061 replace 6082 aluminium sheet?
Marine grade aluminum 6061 and 6082 about specifications
Taking Mingtai Aluminum Industry Co., Ltd. as an example, the thickness of marine-grade aluminum 6061 and 6082 currently produced is more than 0.3mm. It is worth mentioning that the width of marine aluminum 6061 can reach 2600mm, which is one of the few China aluminum plate manufacturers with such production capacity. Customize on demand to make your products unique.
Marine grade aluminum 6061 and 6082 about chemical composition
You should know that most of the performance of aluminum alloys is determined by the chemical composition, so the chemical composition is also important. Their chemical composition is as follows:
Marine grade aluminum 6061: Si 0.40-0.8 Fe 0.7 Cu 0.15-0.40 Mn 0.15 Mg 0.8-1.2 Cr 0.04-0.35 Zn 0.25 Ti 0.15 Al balance.
6082 aluminium sheet: Si 0.7-1.3 Fe 0.5 Cu 0.10 Mn 0.4-1.0 Mg 0.6-1.2 Cr 0.25 Zn 0.20 Ti 0.10 Al balance.
From the chemical composition, it can be seen that the main difference is that the composition ratio of the silicon magnesium of marine grade aluminum 6061 and 6082 is different.
Marine grade aluminum 6061 and 6082 about characteristics
1. The quench sensitivity of 6082 aluminium sheet is higher (compared to 6061 aluminum sheet).
2. Since the composition of 6082 aluminium sheet contains Mn, the corrosion resistance and welding performance are better. Marine grade aluminum, such as shipboards and components on ships, uses it more.
3. 6061 aluminum sheet and 6082 aluminium sheet have similar but not identical mechanical properties. Marine grade aluminum 6061 has good plasticity and weldability. Also has medium strength. It also has excellent corrosion resistance, especially stress-free corrosion cracking tendency.
4. 6061 aluminum sheet usually has good cold working characteristics. It can be anodized and colored, or it can be painted with enamel, suitable for building decoration materials.
5. 6061-T6 temper has the highest value in terms of strength and hardness. 6082-T6 temper has high mechanical properties.
Marine grade aluminum 6061 6082 uses
Marine grade aluminum 6061 and 6082 can be used for marine grade aluminum due to their good corrosion resistance. In addition, they have different uses.
6061 aluminum sheet
The small thickness is widely used in 3C fields such as mobile phone card slots, buttons, computer brackets and computer shells. And the field of trolley cases, aluminum furniture, door panels and door handles; thicker, widely used in underwear molds, shoe molds, precision machining, passenger car decorative plates, pattern plates, car chassis protection parts, four doors and two covers for cars, Automotive wheels, car seats and other fields.
6082 aluminium sheet
Mainly used in transportation and structural engineering industries. Such as bridges, cranes, roof frames, transport planes and transport ships, are ideal materials for manufacturing high-speed ship components. In addition, it can also be applied to camera lenses, couplers, marine accessories and hardware, electronic accessories, etc. Air conditioning tubes, automotive special aluminum, etc.
