2. Aluminium 5083 Physical Properties:

- Density: 5083 aluminium plate alloy has a density of 2.68g/cm³, which makes it a lightweight material suitable for applications requiring weight reduction.
- Melting point: The melting point is 640°C, which is a relatively high melting point, allowing 5083 aluminium alloy to remain stable in high temperature environments.
- Electrical Conductivity: The electrical conductivity is 31.5-35.5% IACS (International Electrotechnical Commission Standard for Electrical Conductivity), which makes 5083 aluminium alloy potentially valuable for electrical applications.
- Coefficient of Linear Expansion: The coefficient of linear expansion is 23 x 10-⁶/K (20-100°C), which reflects the material's dimensional stability during temperature changes.
- Thermal conductivity : 120-160W/(m-K),.

2. Aluminium 5083 Chemical Properties:

Main Chemical Composition: The main chemical composition of 5083 aluminium alloy includes.
- Aluminium (Al): Remainder
- Magnesium (Mg): 4.0-4.9 per cent.
- Magnesium (Mg): 4.0-4.9% Manganese (Mn): 0.40-1.0%
- Chromium (Cr): 0.05-0.25 per cent
- Iron (Fe): ≤0.4%
- Zirconium (Zr): ≤0.25
- Titanium (Ti): ≤0.15
- Copper (Cu): ≤ 0.1%
- Tin (Sn): ≤0.1%
- Silicon (Si): ≤ 0.4

Corrosion resistance: 5083 aluminium alloy has good corrosion resistance and can maintain good performance in seawater and various acidic environments. This makes it the material of choice for shipbuilding and other fields that require seawater corrosion resistance and resistance to seawater corrosion.

5083 aluminium alloy has excellent corrosion resistance, weldability and machinability, and is suitable for shipbuilding in seawater environments, aircraft structures in the aerospace field, and the manufacture of automobiles and railway vehicles. Due to its light weight, high strength and corrosion resistance, 5083 aluminium alloy is widely used in the engineering field.
