EN AW 5083 H321 Marine Grade Aluminum Plate Heavy Gauge 8-260mm MTC EN 10204 3.1

This heavy gauge plate is rolled from EN AW 5083 (AlMg4.5Mn) ingot and supplied in H321 strain-hardened and stabilised temper, the standard condition for hull, offshore and pressure equipment work. Every lot ships with a Mill Test Certificate per EN 10204 3.1 showing heat number, chemical composition and mechanical properties, so your engineering team can file the material traceability package without extra testing.

• Typical tensile strength 305-385 MPa, yield strength 215-295 MPa, elongation 12-16% in H321 temper
• Excellent seawater and salt spray corrosion resistance, no stress corrosion cracking in welded structures
• Superior weldability by MIG / TIG with 5183 or 5356 filler, bendable and machinable after welding
• Suitable for hull plating, deck, superstructure, offshore platform walkways and workboats
