5083 aluminum sheet belongs to the 5000 series Al-Mg alloy family. It offers exceptional corrosion resistance, high mechanical strength, and excellent weldability.
The alloy performs reliably in marine, transportation, and industrial applications exposed to seawater, harsh environments, or low temperatures. Its combination of strength and durability makes it one of the most widely used marine-grade aluminum alloys.
5083 aluminum sheet is a high-strength non-heat treatable Al-Mg-Mn alloy renowned for its exceptional corrosion resistance in marine and chemical environments. It provides outstanding fatigue strength, superior weldability, and excellent mechanical performance at cryogenic temperatures, making it a critical material for heavy-duty structural engineering.
At XQJ Metal, we process and supply certified 5083 aluminum sheets manufactured under strict quality systems in accordance with ASTM B209 and EN 485. We offer custom shearing, cut-to-size dimensions, and protective laser film application for global industrial clients.

Q1: What is the difference between 5083 H116 and H321 tempers?
A: Both H116 and H321 tempers are specifically developed for marine applications, offering superior resistance to intergranular corrosion and exfoliation corrosion.
Q2: What is your Minimum Order Quantity (MOQ) for 5083 aluminum sheet?
A: Our standard MOQ is 1 metric ton per size. Small trial orders or cut-to-length samples can be arranged for standard stock items.
Q3: Can you provide laser-safe PVC film for CNC cutting?
A: Yes, we apply high-quality single-sided or double-sided PE or laser-safe PVC protective film to protect the sheet surface during laser cutting and bending.
