1. What is the difference between Aluminium 5083 O plate and Aluminium 5083 H111 plate?
Aluminium 5083 O plate is in the fully annealed condition, offering maximum ductility and the best possible formability. It is ideal for deep drawing, bending, and shaping processes.
Aluminium 5083 H111 plate is partially strain-hardened after annealing, providing slightly higher strength than the O temper while still maintaining good workability.
Both belong to the Al-Mg-Mn series and are equivalent to grades such as AlMg4.5Mn0.7 in DIN standards and EN AW-5083 in European standards.
2. What are the main properties of Aluminium 5083 O and 5083 H111 plates?
5083 O aluminum plate:
Tensile strength: ~ 270 MPa
Excellent elongation for forming operations
Exceptional corrosion resistance in saltwater environments
5083 H111 aluminum plate:
Tensile strength: ~ 275–320 MPa
Slightly stronger than O temper
Maintains good welding and forming capabilities
GNEE's 5083 O marine aluminum plate and 5083 H111 marine grade plate meet international standards like ASTM B209, EN 485, and ISO for consistent performance.
3. Where are Aluminium 5083 O and 5083 H111 plates used?
5083 O plate: Ship superstructures, cryogenic storage tanks, vehicle body panels, chemical containers.
5083 H111 plate: Hull plating, marine decks, bulkheads, industrial pressure vessels, offshore platforms.
GNEE supplies 5083 O aluminum plate and 5083 H111 aluminum plate to shipyards, engineering contractors, and industrial manufacturers worldwide.
4. How do 5083 O and 5083 H111 perform in marine environments?
Both tempers of 5083 aluminum alloy show outstanding resistance to seawater corrosion, pitting, and stress corrosion cracking.
5083 O marine grade plate is preferred when extensive forming or shaping is needed before final assembly.
5083 H111 marine grade plate is chosen when both strength and formability are required for the marine structure.
GNEE applies strict quality control and advanced surface treatment to enhance corrosion resistance.
