(Al-Mg-Si Series) 5083 shipbuilding aluminum alloy Plate

By mingtaialu More Blogs by This Author


5083 aluminum plate, with thickness more than 6mm and magnesium content between 4.0% - 4.9% by weight, belongs to high-magnesium and non-heat-treatable alloy, and has higher strength and lower formability than 5052 aluminum alloy.
Specification of5083 aluminum sheet
1. Thickness: 0.15-600mm
2. Width: 500-2800mm
3. Length:500-16000mm
4. Temper:H16,H18,H19,H22,H24,H32,H111,H321,etc.
5. Certificate: DNV/ABS/Lioyds/BV
6. Feature: Corrosion resistance, high precision and fatigue resistance.
7. Tensile Strength170360MPa
8. Yield strength (MPa)65
9. Modulus of elasticity(E): 69.370.7Gpa
Applications of 5083 aluminum alloy plates:
1. Shipbuilding: yachts, patrol ships, cargo ships, workboats, fishboats etc.
2. Presure vessels, storage tanks.
3. Vehicle bodies:metro train, tip truck and tank truck bodies etc.
4. Aluminum armor, aircraft welding parts.

The performance of 5083 aluminum sheet
1. Corrosion Resistance
The typical application of 5083 is in the marine environment. with more than 3% mg Mg content, it can be susceptible to stress corrosion cracking, which limits its application temperature to below 65C and also limits the amount of cold work to Hard.
2. Heat Treatment
The 5083 can not be harden by heat treatment. It can be significantly hardened by cold work (cold rolling) and various Htempers are produced most commonly H32 ( Hard) or the similar strength marine tempers H116 and H321 as well as the soft annealed Temper O condition.
3. Welding
It can be Excellent weld-ability by all standard electric, GMAW and GTAW are preferred and widely used to produce structural welds.
