5454 aluminium plates for shipbuilding - haomeialu - 02-24-2018
5454 anti-rust aluminum alloy plates is approximately 20% stronger than alloy 5052, and its properties is roughly similar with 5154. However, in some vicious environment, 5454 has a better corrosion resistance than 5154.
5454 aluminium plates is an alloy in the wrought aluminium-magnesium family (5000 or 5xxx series). It is closely related to 5154 aluminium alloy. As an aluminium-magnesium alloy, it combines moderate-to-high strength with excellent weldability. Like 5154, 5454 aluminium is commonly used in welded structures such as pressure vessels and ships. As a wrought alloy, it can be formed by rolling, extrusion, and forging (although forging is not common), but not casting. It can be cold worked to produce tempers with a higher strength but a lower ductility. It is generally not clad.
- Typical material properties for 5454 aluminum alloy include:[2]Density: 2.69 g/cm3, or 168 lb/ft3.Young's modulus: 70 GPa, or 10 Msi.Electrical conductivity: 34% IACS.Ultimate tensile strength: 240 to 300 MPa, or 35 to 44 ksi.Thermal Conductivity: 130 W/m-K.Thermal Expansion: 22.3 μm/m-K.
